11 # ADVANCE WARNING OF FEATURES TO BE REMOVED OR CHANGED IN FUTURE VERSIONS
12 (There are no plans to remove features from a 6.3.X release, but they may be
13 removed from a 6.4.0 or newer release.)
14 * The MX and host alias DNS lookups that fetchmail performs in multidrop mode
15 are based on assumptions that are rarely met in practice, somewhat defective,
16 deprecated and may be removed from a future fetchmail version.
17 They have never supported IPv6 (including IPv6-mapped IPv4).
18 Non-DNS based alias keywords such as "aka" will remain in fetchmail.
19 * The monitor and interface options may be removed from a future fetchmail
20 version as they are not reasonably portable across operating systems.
21 * POP2 is obsolete, support will be removed from a future fetchmail version.
22 * IMAP2 and IMAP4 (not IMAP4r1) are obsolete, support may be removed from a
23 future fetchmail version.
24 * RPOP is obsolete, support will be removed from a future fetchmail release.
25 * --sslcertck will become a default setting in a future fetchmail version.
26 * The multidrop To/Cc guessing code along with the fragile duplicate suppressor
27 is deprecated and may be removed from a future release.
28 * The "envelope Received" option may be removed from a future release, because
29 the Received header was never meant to be machine-readable, the format varies
30 widely, and various other differences in behavior make parsing Received an
31 unreliable undertaking. The envelope option as such will remain though, in
32 order to support Delivered-To, X-Envelope-To, X-Original-To and similar.
33 See also <http://home.pages.de/~mandree/mail/multidrop>.
34 * The --enable-fallback (fall back to MDA if MTA unavailable) will be removed
35 from a future fetchmail release, because it makes fetchmail's behavior
36 inconsistent and confusing.
37 * The "protocol auto" default inside fetchmail may be removed from a future
38 fetchmail release. Explicit configuration of the protocol is recommended.
39 * Kerberos IV support may be removed from a future fetchmail release.
40 * Kerberos 5 support may be removed from a future fetchmail release.
41 * The --principal option may be removed from a future fetchmail release.
42 * SIGHUP wakeup support may be removed from a future fetchmail release and
43 cause fetchmail to terminate - it was broken for many years.
44 * Support for operating systems that are not sufficiently POSIX compliant may be
45 removed or operation on such systems may be suboptimal for future releases.
46 This means that fetchmail may only continue to work on C99 and POSIX 2001
48 * The maintainer may migrate fetchmail to C++ with STL or C#, and impose further
49 requirements (dependencies), such as Boost or other class libraries.
50 * The softbounce option default will change to "false" in the next release.
51 * The --bsmtp - mode of operation may be removed in a future release.
52 * Given that OpenSSL is severely underdocumented, and needs license exceptions,
53 fetchmail may switch to a different SSL library.
54 * SSLv2 support will be removed from a future fetchmail release. It has been
55 obsolete for more than a decade.
57 --------------------------------------------------------------------------------
59 fetchmail-6.3.23 (not yet released)
62 * Fix compilation with OpenSSL implementations before 0.9.8m that lack
63 SSL_CTX_clear_options. Patch by Earl Chew.
64 Note that the use of older OpenSSL versions with fetchmail is unsupported and
68 fetchmail-6.3.22 (released 2012-08-29, 26077 LoC):
72 NTLM: fetchmail mistook an error message that the server sent in response to
73 an NTLM request for protocol exchange, tried to decode it, and crashed while
74 reading from a bad memory location.
75 Also, with a carefully crafted NTLM challenge packet sent from the server, it
76 would be possible that fetchmail conveyed confidential data not meant for the
77 server through the NTLM response packet.
78 Fix: Detect base64 decoding errors, validate the NTLM challenge, and abort
79 NTLM authentication in case of error.
80 See fetchmail-SA-2012-02.txt for further details.
81 Reported by J. Porter Clark.
84 SSL/TLS (wrapped and STARTTLS): fetchmail used to disable a countermeasure
85 against a certain kind of attack against cipher block chaining initialization
86 vectors (SSL_OP_DONT_INSERT_EMPTY_FRAGMENTS).
87 Whether this creates an exploitable situation, depends on the server and the
89 As a precaution, fetchmail 6.3.22 enables the countermeasure, by clearing
90 SSL_OP_DONT_INSERT_EMPTY_FRAGMENTS.
92 NOTE that this can cause connections to certain non-conforming servers to
93 fail, in which case you can set the environment variable
94 FETCHMAIL_DISABLE_CBC_IV_COUNTERMEASURE to any non-empty value when starting
95 fetchmail to re-instate the compatibility option at the expense of security.
97 Reported by Apple Product Security.
99 For technical details, refer to <http://www.openssl.org/~bodo/tls-cbc.txt>.
100 See fetchmail-SA-2012-01.txt for further details.
103 * The Server certificate: message in verbose mode now appears on stdout like the
104 remainder of the output. Reported by Henry Jensen, to fix Debian Bug #639807.
106 * The GSSAPI-related autoconf code now matches gssapi.c better, and uses
107 a different check to look for GSS_C_NT_HOSTBASED_SERVICE.
108 This fixes the GSSAPI-enabled build on NetBSD 6 Beta.
111 * On systems where SSLv2_client_method isn't defined in OpenSSL (such as
112 newer Debian, and Ubuntu starting with 11.10 oneiric ocelot), don't
113 reference it (to fix the build) and if configured, print a run-time error
114 that the OS does not support SSLv2. Fixes Debian Bug #622054,
115 but note that that bug report has a more thorough patch that does away with
118 * The security and errata notices fetchmail-{EN,SA}-20??-??.txt are now
119 under the more relaxed CC BY-ND 3.0 license (the noncommercial clause
120 was dropped). The Creative Commons address was updated.
122 * The Python-related Makefile.am parts were simplified to avoid an automake
123 1.11.X bug around noinst_PYTHON, Automake Bug #10995.
125 * Configuring fetchmail without SSL now triggers a configure warning,
126 and asks the user to consider running configure --with-ssl.
129 * Some servers, notably Zimbra, return A1234 987 FETCH () in response to
130 a header request, in the face of message corruption. fetchmail now treats
131 these as temporary errors. Report and Patch by Mikulas Patocka, Red Hat.
133 * Some servers, notably Microsoft Exchange, return "A0009 OK FETCH completed."
134 without any header in response to a header request for meeting reminder
135 messages (with a "meeting.ics" attachment). fetchmail now treats these as
136 transient errors. Report by John Connett, Patch by Sunil Shetye.

147 # KNOWN BUGS AND WORKAROUNDS
148 (This section floats upwards through the NEWS file so it stays with the
149 current release information)
150 * Fetchmail does not handle messages without Message-ID header well
151 (See sourceforge.net bug #780933)
152 * BSMTP is mostly untested and errors can cause corrupt output.
153 * Sun Workshop 6 (SPARC) is known to miscompile the configuration file lexer in
154 64-bit mode. Either compile 32-bit code or use GCC to compile 64-bit
155 fetchmail. Note that fetchmail doesn't take advantage of 64-bit code,
156 so compiling 32-bit SPARC code should not cause any difficulties.
157 * Fetchmail does not track pending deletes across crashes.
158 * The command line interface is sometimes a bit stubborn, for instance,
159 fetchmail -s doesn't work with a daemon running.
160 * Linux systems may return duplicates of an IP address in some circumstances if
161 no or no global IPv6 addresses are configured.
162 (No workaround. Ubuntu Bug#582585, Novell Bug#606980.)
163 * Kerberos 5 may be broken, particularly on Heimdal, and provide bogus error
164 messages. This will not be fixed, because the maintainer has no Kerberos 5
165 server to test against. Use GSSAPI.
168 fetchmail-6.3.21 (released 2011-08-21, 26011 LoC):
171 * The IMAP client no longer inserts NUL bytes into the last line of a message
172 when it is not closed with a LF or CRLF sequence. Reported by Antoine Levitt.
173 As a side effect of the fix, and in order to avoid a full rewrite, fetchmail
174 will now CRLF-terminate the last line fetched through IMAP, even if it is
175 originally not terminated by LF or CRLF. This bears no relevance if your
176 messages end up in mbox, but adds line termination for storages (like Maildir)
177 that do not require that the last line be LF- or CRLF-terminated.
180 * There is a patch against fetchnews's source, contrib/rawlog.patch, that can
181 log (and hexdump non-printing characters) raw socket data to a file. It proved
182 useful to debug Antoine's bug described above.
185 fetchmail-6.3.20 (released 2011-06-06, 26005 LoC):
189 STARTTLS: Fetchmail runs the IMAP STARTTLS or POP3 STLS negotiation with the
190 set timeout (default five minutes) now. This was reported missing, with
191 observed fetchmail freezes beyond a week, by Thomas Jarosch.
192 SSL-wrapped connections were unaffected by this timeout, so users of older
193 versions can force ssl-wrapped connections -- if supported by the server --
194 with the --ssl command line or ssl rcfile option.
195 See fetchmail-SA-2011-01.txt for further details.
198 * IMAP: Do not search for UNSEEN messages in ranges. Usually, there are very few
199 new messages and most of the range searches result in nothing. Instead, split
200 the long response to make the IMAP driver think that there are multiple lines
201 of response. (Sunil Shetye)
202 * Do not print "skipping message" for old messages even in verbose mode. If
203 there are too many old messages, the logs just get filled without any real
204 activity. (Sunil Shetye) (suggested by Yunfan Jiang)
205 * Build: fetchmail now always uses its own MD5 implementation rather than trying
206 to find a system library with matched header. The library and header variants
207 found on systems are too diverse, and the code size saving is not worth any
208 more wasted user or programmer time.
211 * Call strlen() only once when removing CRLF from a line. (Sunil Shetye)
212 * fetchmail sets Internet domain sockets to "keepalive" mode now. Note that
213 there is no portable way to configure actual timeouts for this mode, and some
214 systems only support a system-wide timeout setting. fetchmail does not
215 attempt to tune the time spans of keepalive mode.

227 fetchmail-6.3.19 (released 2010-12-10, 25945 LoC):
229 # ERRATUM NOTICE ISSUED
230 * fetchmail 6.3.18 contains several bug fixes that were considered sufficiently
231 grave to warrant the issue of an erratum notice, fetchmail-EN-2010-03.txt.
234 * When specifying multiple local multidrop lists, do not lose wildcard flag.
235 (Affects "user foo is bar baz * is joe here")
236 * In multidrop configurations, an asterisk can now appear anywhere in the list
237 of local users, not just at the end.
238 * In multidrop mode, header parsing is now more verbose in -vv mode, so that it
239 becomes possible to see which header is used.
240 * Make --antispam work from command line (these used to work in rcfiles).
241 Reported by Kees Bakker, BerliOS Bug #17599. (Sunil Shetye)
242 * Smoke test XHTML 1.1 validation, and if it fails, skip validating HTML
243 documents. Skip validating Mailbox-Names-UTF7.html. Several systems have
244 broken XHTML 1.1 DTD installations that jeopardize the build.
245 Reported by Mihail Nechkin against FreeBSD port.
246 Workaround for 6.3.18: build in a separate directory, i. e:
247 mkdir build && cd build && ../configure --options-go-here
248 * Send a NOOP only after a failed STARTTLS in IMAP. (Sunil Shetye)
249 * Demote GSSAPI verbose/debug syslog to INFO severity. Requested by Carlos E. R.
250 and Derek Simkowiak via the fetchmail-users@ mailing list.
251 * Do STARTTLS/STLS negotiation in IMAP/POP3 if it is mandatory even if the
252 server capabilities do not show support for upgradation to TLS.
253 To use this, configure --sslproto tls1. (Sunil Shetye)
254 * IMAP: Understand empty strings as FETCH response, seen on Yahoo. Reported by
255 Yasin Malli to fetchmail-users@ 2010-12-10.
256 Note that fetchmail continues to expect literals as FETCH response for now.
259 * The manual page now links to IANA for GSSAPI service names.

269 fetchmail-6.3.18 (released 2010-10-09, 25936 LoC):
271 # SECURITY IMPROVEMENTS TO DEFANG X.509 CERTIFICATE ABUSE
272 * Fetchmail now only accepts wildcard certificate common names and subject
273 alternative names if they start with "*.". Previous versions would accept
274 wildcards even if no period followed immediately.
275 * Fetchmail now disallows wildcards in certificates to match domain literals
276 (such as 10.9.8.7), or wildcards in domain literals ("*.168.23.23").
277 The test is overly picky and triggers if the pattern (after skipping the
278 initial wildcard "*") or domain consists solely of digits and dots, and thus
279 matches more than needed.
280 * Fetchmail now disallows wildcarding top-level domains.
282 # CRITICAL BUG FIXES AND REGRESSION FIXES
283 * Fetchmail 6.3.15, 6.3.16, and 6.3.17 would pick up libmd5 to obtain MD5*
284 functions, as an effect of an undocumented Solaris MD5 fix.
285 This caused all MD5-related functions to malfunction if, for instance,
286 libmd5.so was installed on other operating systems as part of libwww on
287 machines where long isn't 32-bits, i. e. usually on 64-bit computers.
288 Fixes Gentoo Bug #319283, reported, including libwww hint, by Karl Hakimian.
289 Side effect: fetchmail will now use -lmd on Solaris rather than -lmd5.
290 * Fetchmail 6.3.17 warned about insecure SSL/TLS connections even if a matching
291 --sslfingerprint was specified. This is an omission from an SSL usability
292 change made in 6.3.17.
293 Fixes Debian Bug#580796 reported by Roland Stigge.
294 * Fetchmail will now apply timeouts to the authentication stage.
295 This stage encompasses STARTTLS/STLS negotiation in IMAP/POP3.
296 Reported missing by Thomas Jarosch.
297 * Fetchmail now cancels GSSAPI authentication properly when encountering GSS
298 errors, such as no or unsuitable credentials.
299 It now sends an asterisk on a line by its own, as required in SASL.
300 This fixes protocol synchronization issues that cause Authentication
301 failures, often observed with kerberized MS Exchange servers.
302 Fixes Debian Bug #568455 reported by Patrick Rynhart, and Alan Murrell, to the
303 fetchmail-users list. Fix verified by Thomas Voigtmann and Patrick Rynhart.
306 * Fetchmail will no longer print connection attempts and errors for one host
307 in "silent" and "normal" logging modes, unless all connections fail. This
308 should reduce irritation around refused-connection logging if services are
309 only on an IPv4 socket if the host also supports IPv6. Often observed as
310 connections refused to ::1/25 when the subsequent connection to 127.0.0.1/25
311 then - silently - succeeds. Fetchmail, unless in verbose mode, will collect
312 all connect errors and only report them if all of them fail.
313 * Fetchmail will not try GSSAPI authentication automatically, unless it has GSS
314 credentials. However, if GSSAPI authentication is requested explicitly,
315 fetchmail will always try it.
316 * Fetchmail now parses response to "FETCH n:m RFC822.SIZE" and "FETCH n
317 RFC822.HEADER" in a more flexible manner. (Sunil Shetye)
318 * The manual page clearly states that --principal is for Kerberos 4 only, not
319 for Kerberos 5 or GSSAPI. Found by Thomas Voigtmann.
322 * When encountering incorrect headers, fetchmail will refer to the bad-header
323 option in the manpage.
324 Fixes BerliOS Bug #17272, change suggested by Björn Voigt.
325 * Fetchmail now decodes and reports GSSAPI status codes upon errors.
326 * Fetchmail now autoprobes NTLM also for POP3.
327 * The Fetchmail FAQ has a new item #R15 on authentication failures.
330 * The common NTLM authentication code was factored out from pop3.c and imap.c.

344 fetchmail-6.3.17 (released 2010-05-06, 25767 LoC):
347 * CVE-2010-1167: Fetchmail before release 6.3.17 did not properly sanitize
348 external input (mail headers and UID). When a multi-character locale (such as
349 UTF-8) was in use, this could cause memory exhaustion and thus a denial of
350 service, because fetchmail's report.c functions assumed that non-success of
351 [v]snprintf was due to insufficient buffer size allocation. It would then
352 repeatedly reallocate a larger buffer and fail formatting again.
353 See fetchmail-SA-2010-02.txt.
356 * Fetchmail now supports a --sslcertfile <file> option to specify a "CA bundle"
357 file (a file that contains trusted CA certificates). Since these bundled CA
358 files do not require c_rehash to be run, they are easier to use and immune to
359 OpenSSL library updates that affect the hash function.
360 * Fetchmail now supports a FETCHMAIL_INCLUDE_DEFAULT_X509_CA_CERTS
361 environment variable to force loading the default SSL CA certificate
362 locations even if --sslcertfile or --sslcertpath is used.
363 If neither option is in effect, fetchmail loads the default locations.
366 * Fix string handling in rcfile scanner, which caused fetchmail to misparse a
367 run control file in certain circumstances. Fixes BerliOS bug #14257.
368 Patch by Michael Banack. This fixes a regression introduced before 6.3.0.
371 * Plug memory leak when using a "defaults" entry in the run control file.
372 * Do not print SSL certificate mismatches unless verbose or --sslcertck is
374 * Do not lose "set invisible" in fetchmailconf. (Michael Barnack)
377 * Usability: SSL certificate chains are fully printed in -v -v mode, and there
378 are now helpful pointers to --sslcertpath and c_rehash for "unable to get
379 local issuer certificate" and self-signed certificates -- these usually hint
380 to missing root signing CAs in the certs directory.
381 * Several fixes for compiler (GCC, Intel C++, CLang) and autotools warnings
382 * Memory allocation failures will now cause abnormal program abort (SIGABRT),
383 no longer an exit with unspecified code.
384 * Print a warning if certificate verification failed and the user did not
388 * Fix table of global option to read "set softbounce" where there used to be a
389 2nd copy of "set spambounce". Patch by Michael Banack, BerliOS Bug #17067.
390 * In the --sslcertpath description, mention that OpenSSL upgrade (and a 0.9.X
391 to 1.0.0 upgrade in particular) may require running c_rehash.

407 fetchmail-6.3.16 (released 2010-04-06, 25574 LoC):
410 * Fix --interface option, broken in 6.3.15. Reported by Vladmimir Stavrinov.
411 Fixes Debian Bug #576717.
414 * Call OpenSSL_add_all_algorithms(). This is needed to support non-mandatory
415 and non-standard algorithms in certificates.
416 Sjoerd Simons, to fix Debian Bug #576430.
417 OpenSSL 0.9.8* does not load - for instance - the SHA256 digest by default.
418 Reported as OpenSSL RT#2224.
421 fetchmail-6.3.15 (released 2010-03-28, 25572 LoC):
424 * Fetchmail now supports a bad-header command line or rcfile option that takes
425 exactly one argument, accept or reject (default). This specifies how messages
426 with bad headers retrieved from the current server are to be treated.
429 * In the rcfile, recognize "local" as abbreviation for "localdomains", as
430 documented. The short form has not ever worked since this feature was added in
431 January 1997. Reported by Frédéric Marchal.
432 * Do not close stdout when using mda and "bsmtp -" at the same time.
433 * Log operating system errors when BSMTP writes fail.
434 * Fix verbose mode progress formatting regression from 6.3.10; SMTP trace lines
435 were no longer on a line of their own. Reported by Melchior Franz.
436 * Check seteuid() return value and abort running MDA if switch fails.
437 * Set global flags in a consistent manner. Make --nosoftbounce and
438 --nobounce work from command line (these used to work in rcfiles).
439 Reported and fix confirmed working by N.J. Mann. (Sunil Shetye)
440 * Properly import h_errno declarations, even on systems where h_errno isn't a
441 macro. (Adds ./configure check, fixes Cygwin dllimport warnings.)
444 * The repository has been converted and moved from the Subversion (SVN) format
445 kindly hosted by Graham Wilson over the past years to Git format hosted on
446 Gitorious.org. My deepest thanks to Graham Wilson for this service that
447 kept us going when BerliOS's Subversion service was faulty in its early days.
448 * This opportunity was used to convert BRANCH_6-2 and BRANCH_1-9-9 to
449 GnuPG-signed tags, as a sign that these are now closed.
450 * The outdated SVN trunk is now called "oldtrunk" in Git just to save the work
451 for future reference. All development in the past few years was on BRANCH_6-3.
452 * master was branched from BRANCH_6-3. BRANCH_6-3 is now obsolete (and in fact
453 was also converted to a tag to record where the conversion from SVN to Git
455 * "make check" now skips HTML validation if xmllint or XHTML DTD are missing.
458 * Web site and documentation were adjusted to reflect the SVN->Git move.
459 * The fetchmail manual page is now much clearer on the user id switching
460 (seteuid) when using --mda while running as the super user.

475 fetchmail 6.3.14 (released 2010-02-05, 25487 LoC):
478 * CVE-2010-0562: SSL/TLS certificate information is now also reported properly
479 on computers that consider the "char" type signed. Fixes malloc() buffer
480 overrun. Workaround for older versions: do not use verbose mode.
481 See fetchmail-SA-2010-01.txt for details, including a minimal patch.
484 * The IMAP client no longer skips messages from several IMAP servers including
485 Dovecot if fetchmail's "idle" is in use. Causes were that fetchmail (a)
486 ignored some untagged responses when it should not (b) relied on EXISTS
487 messages in response to EXPUNGE, which aren't mandated by RFC-3501 (the IMAP
488 standard) and aren't sent by Dovecot either.
489 Fix by Sunil Shetye (the fix also consolidates IMAP response handling,
490 improving overall robustness of the IMAP client), bug report and testing by
491 Matt Doran, with further hints from Timo Sirainen.
492 * The SMTP client now recovers from errors (such as servers dropping the
493 connection after errors) when sending an RSET command.
494 Fix by Sunil Shetye. Report by James Moe.
495 * The IMAP client now uses "SEARCH UNSEEN" rather than "SEARCH UNSEEN NOT
496 DELETED" again on IMAP2, to fix a regression in fetchmail 6.2.5 reported by
497 Will Stringer in June 2004. (Sunil Shetye)
498 * The IMAP client now uses "SEARCH UNSEEN UNDELETED" on IMAP4 and IMAP4r1
499 servers (Sunil Shetye).
500 * Workaround: The IMAP client now falls back to "FETCH n:m FLAGS" if the server
501 does not support "SEARCH". (Sunil Shetye)
502 * The IMAP client now requests message numbers in batches of 1,000 to avoid
503 problems if there are more than 1860 unseen messages. (Sunil Shetye)
504 Note that this wasn't security relevant because fetchmail would only read up
505 to the maximum buffer size and leave the remainder of the string unread, going
506 out of synch afterwards.
507 * Stricter validation of IMAP responses containing byte or message counts.
510 * Only include gssapi.h if we're not including gssapi/gssapi.h, to fix a FreeBSD
511 compiler warning about gssapi.h being obsolete.
514 * The README.SSL document was revised for grammar, spelling, and clarity.

522 fetchmail 6.3.13 (released 2009-10-30, 25333 LoC):
525 * The multiline SMTP error fix in release 6.3.12 caused fetchmail to lose
526 message codes 400..599 and treat all of these as temporary error. This would
527 cause messages to be left on the server even if softbounce was turned off.

541 fetchmail 6.3.12 (released 2009-10-05):
544 * The CVE-2009-2666 fix in fetchmail release 6.3.11 caused a free() of
545 unallocated memory on SSL connections, which caused crashes or program aborts
546 on some systems (depending on how initialization and free() of unallocated
547 memory is handled in compiler and libc).
548 Workaround for older versions: run in verbose mode.
549 Patch courtesy of Thomas Heinz, fixes Gentoo Bug #280760.
550 This regression affected only the 6.3.11 release, but not the patch that was
551 part of the security announcement fetchmail-SA-2009-01.
554 * Fix error reporting for GSSAPI on Heimdal (h5l) Kerberos.
555 * Look for MD5_Init in libcrypto rather than libssl, fixes Gentoo Kerberos
556 builds; fixes upstream parts of Gentoo Bugs #231400 and #185652, and fixes
558 * Report multiline SMTP errors properly, reported by Earl Chew; fixes Debian Bug
559 #529899, reported by Akihiro Terasaki.
560 Note: This fix introduced a regression, fixed in 6.3.13.
561 * Replace control characters in SMTP replies by '?'.

575 fetchmail 6.3.11 (released 2009-08-06):
578 * CVE-2009-2666: SSL NUL prefix impersonation attack through NULs in a
579 part of a X.509 certificate's CommonName and subjectAltName fields. These
580 fields use opaque strings with a separate length field, so that the NUL
581 character isn't a special character inside the certificate. Fetchmail, being
582 written in the C language, used to treat these strings as C strings
583 nonetheless, so that the domain comparison would end at the first embedded NUL
584 character, rather than at the real end of the string.
585 Fetchmail will now abort certificate verification as failed if NULs are
586 encountered inside either of these fields regardless of their position, and
587 drop the connection even if --sslcertck is not used, because NUL is not a
588 valid character in legitimate DNS names.
589 See fetchmail-SA-2009-01.txt for details, including a minimal patch.
592 * Remove the spurious message "message delimiter found while scanning headers".
593 RFC-5322 syntax states that the delimiter is part of the body, and the body is
595 * Convert all non-printable characters in certificate Subject/Issuer
596 Common Name or Subject Alternative Name fields to ANSI-C hex escapes (\xnn,
597 where nn are hex digits).
598 Note that this change introduces a regression, fixed in 6.3.12.

606 fetchmail 6.3.10 (released 2009-07-02):
608 # INCOMPATIBLE BUGFIXES AND CHANGES
609 * Fetchmail no longer drops permanently undelivered messages by default, to
610 match historic documentation. It does this by adding a new "softbounce"
612 Fixes Debian Bug#471283, demotes Debian Bug#494418 to wishlist.
613 * There is a new "softbounce" global option that prevents the deletion of
614 messages that have not been forwarded. It defaults to "true" for fetchmail
615 6.3.X in order to match historic documentation. This may change its default
616 in the next major release.
619 * Fix misuse of canonical autoconf target as _TARGET when it should have been
620 _HOST. Report and patch courtesy of Diego E. "Flameeyes" Pettenò.
621 Details: http://blog.flameeyes.eu/2009/01/01/the-canonical-target
622 * Do not lose PS_MAXFETCH (13) exit status when hitting maxpoll. Reported by
623 Michelle Konzack, Debian Bug#508667.
624 * Do not overlap source and destination fields in snprintf() in interface.c.
625 Courtesy of Nico Golde, Debian.
626 * When a pre- or post-connect command fails, now report the exit status or
627 termination signal properly through sys/wait.h macros.
628 * When acquiring a body, understand NIL ("no such data item"), as returned by
629 some MS Exchange versions. Fixes BerliOS Bug #11980 by KB Sriram.
630 * Make progress tickers (-v/--showdots) consistent, and update documentation
631 accordingly ("." for each 1024 octets read, "#" for a header written, and "*"
632 for each body line written.)
633 The conditions under which these had been printed were inconsistent,
634 illogical, and documentation hadn't matched real behaviour for long.
635 * For NTLM authentication, use dynamically allocated buffers.
636 Fixes Debian Bug#449179, reported by Stepan Golosunov.
637 * Non-delivery notice ("bounce mail") now mentions the original reason again,
638 before the address list. This fixes a regression introduced in 6.3.0.
639 * Several compiler warnings were fixed.
640 * The minimum recommended SMTP (RFC-5321) timeouts are enforced to leave
641 sufficient time for the listener to respond. Some synchronous listeners,
642 particularly when used with spam filtering and other policy enforcement
643 services, take extended amounts of time to process messages after the sender,
644 recipient, or data block and EOM line. This can cause fetchmail to not wait
645 long enough for the "250 Ok" and make fetchmail believe the message wasn't
646 properly delivered when in fact it was; fetchmail would then retry the
647 download next time and never make progress.
648 Fixes Berlios Bug #10972, reported by Viktor Binzberger.
649 * The ESMTP/LMTP client will now apply an application-specific timeout while
650 waiting for the EHLO/LHLO response, rather than wait for the server or TCP
652 * Treat 530 errors as temporary, so as not to delete messages on configuration
653 errors. Partially taken from Petr Cerny's patch in Novell Bugzilla #246829.
654 The 501 part of said patch was not added, as the maintainer is not convinced
655 501 is a temporary condition, and softbounce takes care of this anyways.
658 * Make the comparison of the SSL fingerprints case insensitive, to
659 ease its use. Suggested by Daniel Richard G.
660 * Proper precedence ordering for the syslog and logfile options. If the logfile
661 option is effective (i. e. we're in daemon mode and nodetach isn't used),
662 reset the syslog option. If logfile is ineffective (we're not in daemon mode,
663 or nodetach is set), syslog takes precedence.
664 * The sleeping at/awakened at messages appear in logfiles and syslog only if
665 verbose mode is enabled. On the console, they will still appear without
666 verbose mode. Fixes Debian Bug#282259.
667 * fetchmail only requests IPv6 addresses via name service if at least one is
668 configured on the local host, likewise for IPv4. (AI_ADDRCONFIG flag to
669 getaddrinfo()) Extended version of Redhat's patch.
670 * If the server name contains "yahoo.com", offers the "ID" capability, and we're
671 polling via IMAP, send an ID ("guid" "1") transaction first, ignoring its
672 result. This appears needed to be able to log into Yahoo's Zimbra servers, but
673 there are open issues (such as being only able to download one message and
674 server certificate mismatches).
677 * Fix bashism in contrib/fetchsetup. Fixes Debian Bug#530081.
680 * Some parts of the the manual page were revised for clarity, accuracy, and
681 updated recommendations (particularly SSL/TLS) and formatting conventions from
683 * The README and README.SSL documents were updated.
684 * A document, README.SSL-SERVER, was added to describe server-side requirements
685 for proper SSL and/or TLS service offerings. These are not specific to
687 * Documentation on how to make "NOMAIL" (exit code 1) not treated an error has
688 been added to the EXIT CODES section of the manpage and to the FAQ as item C8.
689 The suggested solution uses a tiny POSIX shell script fragment.

707 # SECURITY AND CRITICAL BUG FIXES:
708 * CVE-2007-4565: Denial of service: When fetchmail tries to inject a warning
709 message it created itself, and the message is refused by the SMTP listener,
710 fetchmail dereferences a NULL pointer and crashes. Report & fix by Earl Chew.
711 Note while this is theoretically a remote denial of service attack vector,
712 fetchmail by default talks SMTP to the localhost, so the overall risk is
714 This bug was apparently introduced on 1998-11-27 when the bouncemail facility
715 was modularized. The bug then made its appearance in fetchmail release 4.6.8.
716 See also fetchmail-SA-2007-02.txt.
717 * CVE-2008-2711: Denial of service: When fetchmail logs data blobs
718 (for instance, a To: header in -v -v verbose mode) in excess of 2048
719 bytes, it will crash, because it hands an uninitialized argument
720 pointer (not the format string though) to vsnprintf and reads a
721 random memory location (it calls va_arg() too often without
722 resetting it with va_start()). Based on a patch (BerliOS patch #2492)
723 by Petr Uzel, fixes Novell Bug #354291.
724 Note 6.3.9-rc1 did not completely fix this issue, so it was redrawn a few
725 hours after its release.
726 See also fetchmail-SA-2008-01.txt.
727 * When expunging, mark the right messages as seen to avoid message loss in "keep
728 flush" configurations. Workaround for previous versions: "expunge 0".
729 Report and patch by Alexander Cherepanov - thanks a lot, Berlios Bug #11797,
730 "imap_mark_seen doesn't consider expunged messages".
731 * SSL fix: close memory leak when SSL connection fails; fetchmail used to forget
732 calling SSL_free() on the SSL context, leaking in excess of 500 kB RAM on a
733 x86_64 system per failed SSL connection attempt.
734 Bug reported and patch provided by Seiichi Ikarashi, Fujitsu.
737 * The configure script will additionally check for 'dn_skipname', to fix build
738 failures with µClibc. The new check still recognizes the resolver libraries on
739 Ubuntu 7.04, openSUSE 10.2, Solaris 8, NetBSD 4.0_BETA2 and FreeBSD 6.2.
740 Fixes Gentoo bug #134187.
741 NOTE: this is a bit of a hack, since we twist the HAVE_RES_SEARCH result, but
742 res_search() and dn_skipname() are only used together and scheduled for
743 removal in future versions, so this is probably fine.
744 * No longer complain about invalid sslproto "" when POP3 CAPA probe fails.
745 Fixes Debian Bug#421446 (Holger Leskien), Novell Bug #247233 (Jon Nelson),
747 Thanks to Matthias Strauß for a configuration to reproduce the issue.
748 * Allow .fetchmailrc and .fetchids to be symlinks, as the manpage does not
749 document they aren't allowed - fixes Debian Bug #452907 (Roger Leigh).
750 TOCTOU race persists.
751 * fetchmailconf quotes mailbox (folder) names when writing the configuration.
752 Fixes BerliOS Bug #13207 (reported + fix suggested by Terry Brown).
753 * Only print "Deleting fetchids file" if there actually is one.
754 Fixes Debian Bug#374514, reported by Dan Jacobson.
755 * SSL fix: check and report if SSL_set_fd fails.
758 * autoconf 2.60 is now required to build fetchmail; it uses
759 AC_USE_SYSTEM_EXTENSIONS to replace AC_AIX, AC_MINIX, and the like.
760 * Removed dead FETCHMAIL_DEBUG code from fetchmail.h that was disabled by
761 default with no switches in configure to enable it. However, the macro would
762 have been prone to a symlink attack. Found by Nico Golde.
763 * Removed dead FORCE_STUFFING code from socket.c that was disabled by default
764 with no switches in configure to enable it.
765 * Include the typedef for int16 in the #ifndef _AIX in smbencrypt.c (Peter
767 * Correct check for u_int32_t in configure.ac (seems to be typedef'ed in
768 namser.h on some platforms.) (Peter O'Gorman)
769 * In configure.ac change all CPFLAGS to CPPFLAGS, CEFLAGS to CFLAGS and LDEFLAGS
770 to LDFLAGS otherwise the results of some tests (additional -L and -I flags) do
771 not get used for later tests causing incorrect configure results. Makefile.am
772 was also changed to reflect this. (Peter O'Gorman)
773 * m4/gethostbyname_r.m4 does AC_TRY_COMPILE, which unfortunately can pass even
774 if there is no gethostbyname_r. Changed to AC_TRY_LINK. (Peter O'Gorman)
775 * Revise getnameinfo check to ensure NULL is defined and the result is properly
776 evaluated, to avoid bogus results on for instance FreeBSD and redefinitions of
777 NI_* at compile time. (Matthias Andree).
778 * __attribute__ ((unused)) is a gccism, removed from libesmtp/gethostbyname.c.
780 * In KAME/getnameinfo.c it's best to use the correct argument to inet_ntoa.
782 * In verbose mode, log if --check mode is enabled.
783 * Add sslcommonname option (rcfile and commandline) as a way to work around
784 misconfigured upstream SSL servers that use the wrong certificate name. It
785 specifies which CommonName fetchmail expects and logs. (Daniel Richard G.)
786 * Changed CRLF to LF line endings in contrib/delete-later (reporter: Petr Uzel)
787 * SSL change: enable all workarounds with SSL_CTX_set_options(ctx,SSL_OP_ALL)
788 * All translations have been re-enabled, in an attempt to rekindle translator or
792 * Add fetchmail-SA-2007-02.txt and fetchmail-SA-2008-01.txt.
793 * Re-add two lines to the manual page that had accidentally become comments
794 to nroff. One was part of the --sslproto documentation, and one in the
795 "Awakening the background daemon" section.
796 * The manual page no longer asserts that .fetchids were for exclusive POP3 use,
797 since it is planned to use the file with IMAP4 later.
798 * Add grammar fixes from Dan Jacobson to fetchmail.man. Debian Bug #461642.
799 * The manual page now mentions that user descriptions need to come before user
800 options. Reported by Francensco Pontortì, to fix Debian Bug #467010.
801 * The manual page no longer hints that multi-user declarations per server were
802 only useful in daemon mode running as root, to avoid hinting people to doing
804 * Several manual page rcfile examples now include "ssl".
805 * The manual page hints that option arguments beginning with numbers can be
807 * The manual page now mentions that the --logfile must already exist before
809 * The FAQ now recommends (#I9) not to use Google Mail for their disregard to the
810 protocols they claim to support.
811 * Documentation and program output now /consistently/ claim that the rcfile must
812 not have more than 0700 (u=rwx,g=,o=) permissions, but fetchmail will still
813 silently accept additional g=x permissions for compatibility with previous
814 6.2.X and 6.3.X versions.
815 Inconsistency (program 0710, manpage 0600) reported by Petr Uzel.

840 # SECURITY STRENGTHENING:
841 * Make the APOP challenge parser more distrustful and have it reject challenges
842 that do not conform to RFC-822 msg-id format, in the hope to make mounting
843 man-in-the-middle attacks (MITM) against APOP a bit more difficult.
844 (CVE-2007-1558, reported by Gaëtan Leurent, published 2007-04-02 on Bugtraq)
846 APOP is claimed insecure by Gaëtan Leurent for MITM scenarios for typical
847 setups: based on MD5 collisions, it is purportedly possible to recover the
848 first three characters of the shared secret (password), which would then make
849 recovery of the shared secret a matter of hours or minutes; this would then
850 enable the attacker to impersonate the client vis-à-vis the server.

868 * If SOCKS support was compiled in, add 'socks' to the feature_options Python
869 list emitted in --configdump. Reported by Rob MacGregor.
870 * Do not crash with a null pointer dereference when opening the BSMTP file
871 fails. Improve error checking and reporting. Reported by Reto Schüttel,
872 Debian Bug#416625. Fix based on a patch by Nico Golde.
873 * Make BSMTP output actually work, it would persistently fail with SOCKET error
874 after writing the first header. Bug independently found and reported in

878 * Add fetchmail-SA-2007-01.txt
879 * Extend --mda documentation, discourage use of qmail-inject.
880 Based on a patch by Rob MacGregor.
881 * Document SOCKS configuration facility (SOCKS_CONF environment variable).

883 * Use envelope option in multidrop example. Patch by Rob MacGregor.
884 * Document expected Received: line format when parsing for envelope addressees.
885 * Stripped option documentation from sample.rcfile, since this is bound to go
886 out of synch with the manual page, which is the only reference on options.
887 * Mention that --limit default is 0 bytes, which is special for "no limit".

912 fetchmail 6.3.6 (released 2007-01-04):
915 * CVE-2006-5867, fetchmail-SA-2006-02.txt:
916 Password disclosure vulnerability fixed. This has several aspects:
918 - Fetchmail now implies sslproto 'tls1' if the sslfingerprint or sslcertck
919 options are used and the ssl option is not used, in order to be sure that
920 fetchmail gets a certificate from the mail server.
922 - Fetchmail breaks the connection if the TLS negotiation (or verification, if
923 requested) fails with sslproto 'tls1', sslfingerprint or sslcheck enabled.
925 - POP3 connections now use STLS reliably. They used to ignore STLS altogether
926 for serveral values of the "auth" option, when fetchmail forget to probe
927 server capabilities - see fetchmail-SA-2006-02.txt for details.
929 - POP3 connections will no longer fall back USER/PASS authentication if
930 strong challenge-response authenticators such as CRAM-MD5 are configured
931 but the server does not advertise these in its CAPA response.
933 - POP2 is obsolete and does not support STLS or anything beyond password-based
934 authentication. The attempt to use STLS or strong authenticators now causes
937 Configurations using both ssl and sslcertck however have been semi-safe in
938 that they would send the password in the clear. The USER/PASS fallback
939 problem however applies to these too, so that the password was only safe on
942 * CVE-2006-5974, fetchmail-SA-2006-03.txt:
943 Repairs a regression in 6.3.5 that crashes fetchmail when a message with
944 invalid headers is found while fetchmail's mda option is in use. BerliOS bugs
945 #9364, #9412, #9449. Stack backtrace provided by Neil Hoggarth - thanks.
947 # REGRESSION FIXES (recently introduced bugs)
948 * Repair --logfile, broken in 6.3.5. BerliOS Bug #9059,
949 reported by Brian Harring.
950 * Repair --user, broken in 6.3.5 (as a side effect of the authenticate external
951 patch): using SSL certificate/key authentication overrode the --user option.
952 Now the latter takes precedence, and only defaults to the certificate's common
953 name. Debian Bug #400950, reported by Jorgen Schaefer <forcer@debian.org>.
955 # BUG FIXES (long-standing bugs):
956 * RPOP: used to log the password locally rather than an asterisk as the other
957 protocols do. The password is now shrouded in the local logs.
958 * POP3: Probes capabilities now when Kerberos V5 is enabled, so that we can
959 actually detect if the server supports it.
960 * Robustness: If a stale lockfile cannot be deleted, truncate it so that
961 fetchmail doesn't later believe itself to be running if the PID is recycled
962 by a non-fetchmail process.
963 * DNS: Detect /etc/resolv.conf changes: On systems that have res_search(),
964 assume we also have res_init() and call it (suggested by Ulrich Drepper,
965 glibc bug #3675) in order to make libc or libresolv reread the resolver
966 configuration at the beginning of a poll cycle. This is important when
967 fetchmail is in daemon mode and /etc/resolv.conf is changed later by dhcpcd,
968 dhclient, pppd, openvpn or other ip-up/ipchange scripts. Should fix Debian
969 Bug#389270, Bug#391698.
970 * Robustness: Fix crash on systems that do not provide strdup(), the crash
971 happens only in out-of-memory conditions when fetchmail cannot proceed
972 anyways. Patch by Andreas Krennmair.
973 * Robustness: When HOME and FETCHMAILHOME are unset, be sure to copy user
974 database information, so it is not trashed later. Patch by Jim Correia.
977 * Workaround: Improve handling of IMAP IDLE, some servers do not reset their
978 time counters after sending information asynchronously. Patch by Sunil
979 Shetye, after report from Andrew Baumann.
980 * Usability: When requesting Kerberos or GSSAPI, complain and exit with syntax
981 error if any of these requested features has not been compiled in. This is
982 to fail early and with precise error message. Reported by Isaac Wilcox.
983 * --version will now add +KRB4 or +KRB5 if Kerberos v4 or v5, respectively, have
984 been compiled in. Reported missing by Isaac Wilcox.
987 * New en_GB (British English) translation by David Lodge.
988 * Update Japanese (Takeshi Hamasaki), Polish (Jakub Bogusz), Russian (Pavel
989 Maryanov) and Vietnamese (Clytie Siddall) translations.
990 ! Note that not all these translations are complete -- this isn't the
991 translators' fault though, but due to delays at the BerliOS hosting site and
992 the translation project handlers. You may see a few untranslated messages.
995 * Dropped exit status 15 from manual page, it's not used by fetchmail.
996 Reported by Isaac Wilcox.
997 * Documented exit codes 24 - 29 as internal.
999 fetchmail 6.3.5 (released 2006-10-09):
1002 * For protocols such as IMAP that are not delimited by "." lines, truncate the
1003 input buffer when the message has been completely read, to avoid taking
1004 trailing garbage into the message if the terminal CRLF is missing. Fixes
1005 Debian Bug#312415. (Patch suggested by Mike Jones, Manchester Univ.).
1006 * When using NTLM authentication, use regular IMAP response code handler after
1007 completing NTLM handshake, for robustness and consistency.
1008 (Taken from the NetBSD portable packages collection, patch-ac.)
1009 * Support Kerberos installations where krb5.h and perhaps roken.h are in
1010 .../include/krb5. Taken from NetBSD portable packages collection patch-ae.
1011 * On NetBSD, link against -lroken -lcom_err if --with-kerberos is enabled.
1012 * Drop #include <com_err.h> from Kerberos 5 header file, fixes compile error on
1014 * Fix des_pcbc_encrypt compile warnings in kerberos.c line 246.
1015 * If krb5-config provides gssapi library information, use that rather than
1017 * Improve --with-gssapi auto detection for /usr-based GSSAPI installs.
1018 * Fix --with-gssapi builds for NetBSD 3.0.
1019 * Improve KAME/getnameinfo.c portability to Linux libc5 systems.
1020 Based on a patch by Dan Fandrich.
1021 * Provide INET6 to KAME/getnameinfo.c (only useful on IPv6-enabled systems that
1022 lack getnameinfo, and there only visible in some Received: headers).
1023 Found by Dan Fandrich.
1024 * POP3: some UID flags may not be set properly on UIDL lists. (Sunil Shetye)
1025 * Make IMAP4 IDLE work on servers that do not update RECENT counts.
1026 Reported by Lars Tewes.
1027 * IMAP4 patch by Sunil Shetye:
1028 - do not depend on server updating RECENT counts at all
1029 - also enter IDLE loop when messages are present on the server.
1030 * Fix --flush description in the manual page, fetchmail does not mark messages
1031 seen unless it has successfully delivered them. Suggested by Frederic Marchal.
1032 * Fetchmail no longer attempts to stat the "-" file in daemon mode -- this is a
1033 special name to read the RC file from stdin, and cannot always be re-read
1034 anyways. BerliOS bug #7858.
1035 * When looking up ports for a service, the lookup succeeds and the returned
1036 address family isn't IPv4 or IPv6, properly free the allocated memory from the
1037 service lookup. Found by Uli Zappe.
1038 * When looking up ports for a service, only look up TCP ports.
1039 * Avoid compiling empty files, to avoid diagnostics from strict compilers.
1040 * If the lockfile ends before the process ID, treat it as stale and unlink it.
1041 Reported by Justin Pryzby, Debian Bug #376603.
1042 * SIGHUP wake-up behavior was broken since 5.9.13's Cygwin changes, in that for
1043 non-root users, SIGHUP would abort the first poll and subsequently interfere
1044 with new polls, and SIGHUP would be ignored for root users. SIGHUP now matches
1045 documented behavior. SIGUSR1 has always been a wakeup signal for both root
1046 (undocumented) and non-root users. See also the deprecation warning above.
1047 * Track getaddrinfo() results to properly free them after timeouts and make sure
1048 that getaddrinfo() isn't interrupted by a timeout (which breaks on MacOS X),
1049 reported by Uli Zappe. This should fix Debian Bug#294547 and Bug#377135.
1050 * --logfile is now handled more carefully, errors opening the logfile are
1051 now reported to the TTY where fetchmail was started from.
1052 * fetchmail now complains and aborts when it cannot properly daemonize itself.
1053 * fix compilation on systems that don't know struct addrinfo (Solaris 2.6).
1054 * ignore SIGPIPE signals and rely on functions to return EPIPE instead. This is
1055 necessary because the former longjmp() from the signal handler is unsafe and
1056 makes the whole fetchmail behavior undefined after the event.
1057 * Avoid crash in env.c/host_fqdn if we cannot canonicalize our own hostname.
1058 Reported by Alexander Holler.
1059 * SSL fix by Miloslav Trmac (Red Hat): free the SSL contexts after the
1060 connection, to avoid from growing SSL certpaths without bounds, avoid using
1061 SSL contexts for unrelated connections, and to fix Red Hat Bug #206346.
1064 * Rename all fetchmail-internal lock_* functions to fm_lock_*. Obsoletes
1065 NetBSD portable packages collection patch-ah, patch-ai and patch-aj.
1066 * Configure prints a warning (but proceeds) if Kerberos IV support is enabled.
1067 * In verbose mode, log every IP fetchmail tries to connect to, to avoid
1068 misleading the user. Suppress EAFNOSUPPORT errors from socket() call, too.
1069 Fixes Debian Bug #361825, reported by Daniel Baur.
1070 * In idle mode, fetchmail complains about the fetchall option.
1071 * When a connection fails, log not only the IP address, but also host and
1072 service name and the port number. Log the latter when trying to connect in
1074 * Keep syslog output at one line per message (this works if no errors occur).
1075 * Fetchmail in verbose mode now logs if it opportunistically upgrades a POP3
1076 or IMAP connection to TLS security with STLS/STARTTLS.
1077 * fetchmail now supports foo@example.org=bar user mappings for multidrop boxes.
1078 * switch setjmp/longjmp to sigsetjmp/siglongjmp
1079 * IMAP now supports the EXTERNAL authentication method, courtesy of
1080 Götz 'nimrill' Babin-Ebell, BerliOS patch #1095 with minor changes.
1081 Note that this change causes --sslcert to override --user.
1082 * The sslproto keywords are now case insensitive, courtesy of
1083 Götz 'nimrill' Babin-Ebell, BerliOS patch #1095.
1084 * When going to sleep, log for how long. Suggested by Claudia Ludwig.
1085 * When the server name cannot be canonicalized, log the gai_strerror value.
1087 # TRANSLATION UPDATES:
1088 * Catalan/ca (Ernest Adrogué Calveras), Japanese/ja (Takeshi Hamasaki) - also
1089 made gettext 0.15 ready, Polish/pl (Jakub Bogusz), Russian/ru (Pavel
1090 Maryanov), Spanish/es (Héctor García Álvarez), Vietnamese/vi (Clytie Siddall)
1092 # CONTRIBUTED SCRIPTS:
1093 * PopDel.py was revised by Joshua Crawford to display the From: address and
1094 list every email, even if it has no Subject: header; and not delete the wrong
1095 message in the presence of mail without Subject: headers.
1097 fetchmail 6.3.4 (released 2006-04-14):
1100 * configure: detect res_* functions properly with newer glibc ABIs.
1101 Patch by Miloslav Trmac.
1102 * tracepolls: add folder information if available. Reported by Terry Brown.
1103 * lexer: add %option noyywrap to avoid link errors about missing yywrap().
1104 * a few more type fixes for report/snprintf, patch by Miloslav Trmac.
1105 * bouncing: fetchmail would still send "General SMTP/ESMTP error." bounces
1106 in spite of "no bouncemail" configuration.
1107 * SSL/TLS: if, for a certain server, an sslfingerprint is specified and
1108 sslcertck is NOT set, suppress printing SSL certificate mismatch errors.
1109 (Reported by Hannes Erven.)
1110 * SSL/TLS: always print if the sslfingerprint mismatches, even in silent
1111 mode. (This is for consistency with certificate verification errors.)
1113 # TRANSLATION UPDATES:
1114 * German/de (Matthias Andree), French/fr (Matthias Andree), Spanish/es (Héctor
1115 García), Polish/pl (Jakub Bogusz), Japanese/ja (Takeshi Hamasaki)
1116 * New Vietnamese/vi translation (Clytie Siddall).
1117 * Updated French descriptions for the .spec file (Stéphane Schildknecht,
1118 Luc Pionchon, Matthias Andree).
1121 * pidfile: there is a new command-line (--pidfile PATH) and global option for
1122 the rcfile (set pidfile [=] "/path/to/pidfile") option to allow overriding
1123 the default location of the PID file.
1124 Requested by Héctor García, Debian maintainer.
1125 * specgen.sh: Converted to UTF-8 to support translated texts better.
1127 fetchmail 6.3.3 (released 2006-03-30):
1130 * SEGFAULT: Do not attempt to overwrite the netrc password if none has been
1131 specified. This fixes a segmentation fault bug introduced into 6.3.2.
1132 Fixes BerliOS bug #6234. BerliOS patch #804 by Craig Leres.
1133 The patch, as accepted into fetchmail, was available separately from
1134 <http://download.berlios.de/fetchmail/patch-6.3.2.1-fix-netrc-SIGSEGV.diff>
1135 * SEGFAULT: Work around C libraries that return a NULL in getaddrinfo()'s
1136 ai_canonname record, to avoid a segfault. Affects for instance FreeBSD 4.10,
1137 4.11 and 5.3 when dotted quads are given as server names.
1138 Analysis and fix by Vladimir Olegovich Ravodin (Владимир Олегович Раводин).
1139 * IMAP: fix hangs in NOOP-based IDLE emulation. Reported by Casper Gripenberg
1140 and Brendan Lynch, fix by Sunil Shetye (his patch was merged) and Brendan Lynch.
1141 * IMAP: Handle other clients concurrently accessing IMAP mailboxes better.
1142 Fetchmail quits the poll if the EXPUNGE count does not match expectations, and
1143 servers not updating RECENT counts after EXPUNGE are handled in a better way.
1144 (Patch by Sunil Shetye.)
1145 * IMAP: Stop sending EXPUNGE after NOOP-idling (patch by Sunil Shetye).
1146 * POP3: fetchmail can now use UIDL in fetchall keep mode, to avoid re-fetching
1147 the same messages again when the fetchall keyword is removed. Patch by
1148 Sunil Shetye. For details, please see
1149 <http://lists.berlios.de/pipermail/fetchmail-users/2006-March/000308.html>
1150 * LMTP: fix bug in LMTP port validation (patch by Miloslav Trmac).
1151 * SDPS: fetchmail no longer replaces the local user ID for an empty envelope
1152 sender when using the proprietary SDPS extension for POP3.
1153 Fixes Debian Bug#353575, reported by Roger Lynn.
1154 * SDPS: Warn and disable SDPS if POP3 is disabled to avoid compilation errors.
1155 * fetchmail no longer prints empty lines in verbose mode when using syslog.
1156 * fetchmail no longer prints UID lists in verbose mode when using syslog.
1157 * ./configure --quiet is now quieter (no SSL and fallback-related output).
1158 * Miloslav Trmac's patch (with minor changes) to fix char * sign consistency,
1159 unused arguments and variables.
1160 * More signedness, unused argument/variable and other warning fixes.
1163 * --idle can now be specified on the command line, too.
1164 * --fetchall is now supported on the command-line.
1165 * POP3: Lower default fastuidl span to 4 (i. e. every 4th run fetches the
1166 whole UIDL list), patch by Sunil Shetye.
1169 * "ssl" is a user option rather than a server option. Patch by Nico Golde.
1170 Fixes Debian Bug#354661, reported by Keith Hellman.
1171 * The manual page now suggests "--" before the addresses in the sendmail MDA
1172 example, for safety.
1173 * The FAQ item X9, Domino IMAP omits Content-Transfer-Encoding header, was
1174 added. Information provided by Anthony Kim on the fetchmail-friends list
1176 * Credit Chris Boyle with the NOOP emulation code for IDLE in fetchmail 6.2.4.
1177 Eric forgot to credit Chris, thanks to Sunil Shetye for providing these links:
1178 http://lists.ccil.org/pipermail/fetchmail-friends/2003-July/007705.html
1179 http://lists.ccil.org/pipermail/fetchmail-friends/2003-July/007713.html
1180 * Added a section about RETR vs. TOP to the manual page.
1181 * Changed section/subsection levels in some areas.
1183 fetchmail 6.3.2 (released 2006-01-22):
1185 Unless otherwise noted, changes to this release were made by Matthias Andree.
1187 # SECURITY FIX IN THIS RELEASE
1188 * CVE-2006-0321: Fix segfault or bus error after bouncing a message. This bug
1189 was introduced into 6.3.0 when removing alloca(); it caused fetchmail to free
1190 random memory. Reported by Nathaniel W. Turner, Debian Bug#348747.
1191 See fetchmail-SA-2006-01.txt
1193 # INCOMPATIBLE CHANGE:
1194 * Automatically disable the POP3 TOP command if the greeting string contains
1195 "Maillennium POP3/PROXY server", which is used by comcast and known to
1196 truncate messages after 80 kByte. Fall back to RETR, and complain if we had
1197 used TOP otherwise (the warning is printed only once per server in daemon
1198 mode). Suggested by Ed Wilts.
1199 *Note* that this means messages are marked read on these servers, which is a
1200 deviation from how 6.3.1 behaved, but we have no alternative, comcast haven't
1201 fixed this bug in years. Preventing the loss of the remainder of the message
1202 justifies this incompatible fix.
1203 * fetchmail, since 6.3.0, requires write permission to the directory holding the
1204 idfile. See the amendment in the 6.3.0 MAJOR INCOMPATIBLE CHANGES section
1205 below for details. The manual page was updated.
1207 # CHANGES RELEVANT TO PACKAGERS:
1208 * The outdated BUGS document was removed from the distribution.
1209 * Added fetchmail-SA-2006-01.txt to the distribution.
1212 * SMTP/LMTP cleanup to fix these two bugs:
1213 - switch back to SMTP after having tried LMTP hosts (multiple smtphost hosts)
1214 - switch back to LMTP after sending a bounce.
1215 The patch removes the global state variable that was the root of this problem.
1216 Patch by Sunil Shetye. (MA)
1217 * Don't complain about fetchall keep in --configdump mode. Bug introduced in
1219 * fetchmailconf.py: Fix novice help for Poll interval and fetchall.
1220 Reported by Justin Pryzby, Debian Bug #344978.
1221 * Some verbose output disappeared in debug mode. Adding further -v options would
1222 alternate between verbose and debug mode. debug mode now comprises all verbose
1223 output, and adding more -v options does not switch back from debug to verbose
1225 * fetchmail.man: Fix accented characters in Héctor García's name. Merged from
1226 downstream debian/patches/01_man_page.dpatch.
1227 * Add missing --help text for "--sslcertck" option.
1228 * fetchmailconf.py: Accept --help and --version.
1229 * fetchmail --version now prints the copyright notice.
1230 * don't complain about READ-ONLY IMAP folders in --fetchall --keep mode.
1231 Reported Alexander Zangerl, Debian Bug#348964.
1232 * the RPM .spec file now generates a -debuginfo package on newer RPM versions.
1234 fetchmail 6.3.1 (released 2005-12-19):
1236 # SECURITY FIX IN THIS RELEASE
1237 * CVE-2005-4348 Fix segmentation fault (null pointer dereference) in
1238 multidrop mode with headerless email. See fetchmail-SA-2005-03.txt.
1239 Reported by Daniel Drake, patch by Sunil Shetye. (MA)
1241 # OTHER BUG FIXES, DOCUMENTATION AND TRANSLATION UPDATES
1242 * Fix broken default port in POP2. Patch by Stanislav Brabec, SUSE [CZ]. (MA)
1243 * Fix manual page, some lines starting with ' were escaped by \&.
1244 Reported by Simon Barner. (MA)
1245 * Ship with gettext-0.14.3 again, as 6.2.9-rc10 did. Found by Sunil Shetye. (MA)
1246 * Actually set default SSL certificate path if --sslcertpath is unset.
1247 Reported by Heino Tiedemann and Rob MacGregor. (MA)
1248 * Remove bogus Netscape IMAP4rev1 Service >= 3.6 warning about BODY[TEXT]
1249 that we are not using. Patch by Sunil Shetye. (MA)
1250 * Plug potential memory and socket leak when polling multiple folders or when
1251 the upstream sends bogus message sizes. Patch by Sunil Shetye. (MA)
1252 * Update Catalan translation, by Ernest Adrogué Calveras. (MA)
1253 * Fix segfault (null pointer dereference) on some operating systems with
1254 fetchmail's obsolete DNS MX/host alias lookups in multidrop mode.
1255 Patch by Dr.-Ing. Andreas Haakh. (MA)
1256 * Close SMTP sockets early, to reduce resource usage, trigger earlier delivery
1257 with some MTAs and avoid SIGPIPE (SIG 13) when the SMTP listener gets bored
1258 and drops the connection after timeout. Patch by Sunil Shetye. (MA)
1259 * Don't treat hitting a fetch limit as error. Patch by Sunil Shetye. (MA)
1260 * Fix negative "messages left on server" on idle/repoll with fetchlimit.
1261 Patch by Sunil Shetye. (MA)
1262 * Properly track logout stage. Patch by Sunil Shetye. (MA)
1263 * Preserve error conditions across postconnect script. Sunil Shetye. (MA)
1264 * Do not trash destination domain if multiple messages are forwarded into the
1265 same SMTP/LMTP connection. Reported by Joachim Feise, Berlios Bug #5849. (MA)
1266 * Manual page: Add "-md5" to "openssl x509" example in --sslfingerprint
1267 documentation, since OpenSSL 0.9.8 changed the default to SHA1.
1268 Suggested by Jason White. (MA)
1269 * Cope with servers that return UID information in response to non-UID
1270 RFC822.{SIZE|HEADER} requests. Reported by Jason White.
1271 Patch suggestion by by Sunil Shetye, simplified by MA.
1273 fetchmail 6.3.0 (released 2005-11-30):
1275 # SECURITY FIXES IN THIS RELEASE
1276 * CVE-2005-2335: The POP3 UIDL code doesn't sufficiently validate/truncate the
1277 input length, so a (malicious or compromised) server that sends UIDs longer
1278 than 128 bytes can corrupt fetchmail's stack and crash fetchmail.
1279 This vulnerability is remotely exploitable to inject code run in a
1280 root shell. Edward J. Shornock, Ludwig Nussel. fetchmail-SA-2005-01.txt
1281 * CVE-2005-3088: fetchmailconf now changes the output file to mode 0600 BEFORE
1282 writing to it, so there is no window where passwords could be read by the
1283 world. Matthias Andree. fetchmail-SA-2005-02.txt
1285 # MAJOR INCOMPATIBLE CHANGES
1286 * Remove support for --netsec/-T options, the required inet6_apps library is no
1288 http://www.inner.net/pub/ipv6/ states, as of 2005-07-03: "/pub/ipv6
1289 Our IPv6 software is now long defunct. Please find a more modern source."
1290 I haven't been able to find a more modern source. Matthias Andree
1291 * Operating systems that do not conform to the Single Unix Specification v2
1292 (1997) or v3 (2001, aka IEEE Std 1003.1-2001) are no longer supported. They
1293 may continue to work and non-intrusive patches to support them may be
1294 accepted. Matthias Andree
1295 * The default for --smtphost is now always "localhost" regardless of
1296 authentication types and protocols, so as to simplify configurations for
1297 workstations where the SMTP daemon only listens on the loopback interface.
1298 Sunil Shetye & Matthias Andree
1299 Amendment, 2006-01-04:
1300 * fetchmail's idfile (.fetchids) is no longer written directly, but the ids are
1301 written to a temporary file which is renamed into place after being written
1302 completely. This is to avoid writing incomplete idfiles when running out of
1303 space, which would cause excessive duplicate refetches of messages, this might
1304 make matters even worse. This means that fetchmail requires write permission
1305 on the directory holding the idfile. This will usually affect system-global
1306 daemons only, for instance, Debian. Found by Dan Jacobson. Matthias Andree.
1307 Escalated to "incompatible", 2006-01-13:
1308 * Try to obtain FQDN as our own host by default, rather than using "localhost".
1309 If hostname cannot be qualified, complain noisily and continue, unless
1310 Kerberos, ODMR or ETRN are used (these have always required an FQDN).
1311 Partial fix of Debian Bug#150137. Fixes Debian Bug#316454. Matthias Andree
1313 # CHANGES RELEVANT TO PACKAGERS AND USERS
1314 * fetchmailconf is now a shell wrapper that calls the byte-compiled
1315 fetchmailconf.py script, which is now installed in the regular python
1316 directory. Matthias Andree.
1317 * The --enable-inet6 configure option was removed. The code is mostly protocol
1318 agnostic, a fully IPv6 aware OS is expected to provide getaddrinfo(),
1319 getnameinfo() and the macro AF_INET6. Matthias Andree.
1320 * gettext (intl/) has been removed from the fetchmail package. Install GNU
1321 gettext 0.14 separately for NLS (i18n). Matthias Andree
1322 * Added Russian translation, courtesy of Pavel Maryanov of the
1323 Russian translation team. (MA)
1324 * Updated and re-enabled Czech translation, by Miloslav Trmac (MA).
1325 * Dropped da=Danish, el=Greek and tr=Turkish translations which have more than
1326 10% (61+) untranslated or fuzzy messages. Matthias Andree.
1328 # OTHER USER-VISIBLE CHANGES

1343 Patch by Phil Endecott. (RF)
1344 * Build fixes for HESIOD and resolv.h trouble on FreeBSD. (MA)
1345 * Fabrice Bellet's fix for Red Hat bug #113492, fetchmail hangs in IMAP
1346 mode after EXPUNGE when the server (Dovecot 0.99.10) doesn't update
1347 RECENT and EXISTS counts. (MA)
1348 * Holger Mauermann's bounce patch, to use a NULL envelope from, not
1349 write a Return-Path header (both to meet RFC-2821), changed From,
1350 added Subject header, rewording the human readable part. Fixes Debian
1352 * Merge Sunil Shetye's time.h handling fix. (MA)
1353 * Merge Gerd von Egidy's patch to avoid a segfault in multidrop/received
1354 mode when the Received: headers are malformatted. (MA)
1355 * MIME-encode bodies and Subject headers of warning messages, limiting
1356 the header to 7 bits. (MA)
1357 * Normalize most locale codesets to IANA codesets, based on
1358 norm_charmap.c by Markus Kuhn. (MA)
1359 * Remove sleep(3) after POP3 login, patch by Brian Candler. (MA)
1360 * Fix option parsing bug that trashes the showdots setting when more
1361 than one server is configured. Patch by Brian Candler. (MA)
1362 * Honor sslcertpath setting even if sslcertck is unset. Patch by Brian
1364 * SSL certificate checking fixes, don't display same error message twice
1365 in succession, make sure that Common Name and fingerprint checking are
1366 only done once. Print all validation warnings/errors even if not in
1367 verbose mode. Patch by Brian Candler. (MA)

1429 design-notes.html document. The NOTES file will contain both of them.

1432 fails. Fix suggested by Goswin Brederlow. (MA)
1433 * Really fix Debian Bug#207919 (garbage in Received: lines when smtphost set),
1434 patch by Tobias Diedrich. The 6.2.5 NEWS claimed Gregan's patch had fixed

1501 also offers MSN and NTLM, suggested by Yves Boisjoly. Matthias Andree
