fetchmail-4.3.7 (Tue Feb 17 21:30:26 EST 1998)
* Fixed a minor bug in the IMAP re-polling logic.
* Nicholas Pitre's extensive changes to multidrop:

  - Seek for the true sender of a mail which is not necessarily in the
    From: header. (see comments in the code for more explicit details).
    This one is particularly important with list distributions...

  - Respect the Resent-To/-Cc/-Bcc precedence over the To/Cc/Bcc headers
    for recipient delivery.  So avoid resending a message to a person who
    just resent a mail to some other addresses.

  - Fix a bug in find_server_names() wich caused recipient addresses to
    figure twice in the recipient address list.

  - Modified parse_received()  to let full adress from the Received header to
    pass through so local domains can be used (now has same policy as in
    the find_server_names() function).

  - Fixed memory leaks from readheaders().

  - Made some strcmp() be strcasecmp() as it should be because it didn't
    work correctly in some cases.

  - Modified reply_hack() to meet the needs of above modifications.

  Thomas says these changes have been tested for two weeks in a production
  multidrop environment.  I tested them for another week in mine.

  to force the hostname used in MAIL FROM lines.
* If link can't find the bind library, force `no dns' on all connections.
* Change name of ordinary-user lockfile so .fetchmail can be used as a
  logging directory.

* Prevent header rewrite logic from appending mailserver name to blank To.
* When header rewrite is on, hack Return-Path as well.

There are 240 people on the fetchmail-friends list.

pl 3.9.2 (Wed Apr 23 14:07:03 EDT 1997):
* Fixed a glitch in the Makefile yacc and lex productions

fetchmail-3.9 (Wed Apr  2 13:36:22 EST 1997)

features --

* It is now possible to set a default poll interval with `set daemon'.

* -U/uidl option to force UIDL use under POP3 (thanks, Ingmar Baumgart).

bugs -- 

* Server-response timeouts were broken.  Various symptoms of this problem
  were reported by Klee Dienes <klee@mit.edu>, Dirk Eddelbuettel
  <edd@rosebud.sps.queensu.ca>, Robert V. Schipper <rvs@gol.com>,
  and Steven Brown <swbrown@ucsd.edu>.

* George Sipe sent a fix for the --monitor code.

* --norewrite was a no-op.  Fixed.

* Fetchmail was aborting with "partial message buffer overflow" on Suns
  due to unreliable vsprintf return.  This has been fixed with changes
  to error.c.

There are 268 people on the fetchmail-friends list.

------------------------------------------------------------------------------
fetchmail-3.8 (Fri Mar  7 17:34:02 EST 1997)

features --

* More FAQ material on using `localdomains'.

* Compilation hacks for ISC 4.0 (thanks, Larry Jones!).

bugs --

* Enabled ETRN and RPOP command-line options.

* Yet another attempt to fix the error.c compilation problems under
  Solaris and NEXTSTEP.

* Handle \( and \) correctly in RFC822 comments, thanks to Gareth McCaughan.

* Fixed off-by-one error fingered by Brian Jones that prevented
  `localdomains' from working.

There are 248 people on the fetchmail-friends list.

------------------------------------------------------------------------------
fetchmail-3.7 (Fri Feb 21 17:38:40 EST 1997)

features --

* You can now specify a hunt list of SMTP forwarding hosts.

* Treat unexpected EOF as a protocol error.

* DNS errors no longer abort an entire poll.  Instead they just cause 
  forwarding and deletion of the current message to be suppressed.  

* -v output now includes the version/pl numbers (help for harried maintainer!).

bugs --

* Fix password-shrouding logic so it doesn't crap out on a zero-length
  password.

* Various error-logging fixes by Dave Bodenstab.

* Fix parsing bug that broke UIDL-processing code.

There are 233 people on the fetchmail-friends list.

------------------------------------------------------------------------------
fetchmail-3.6 (Mon Feb 17 00:19:55 EST 1997)

features --

* Use Return-Path for RCPT FROM if possible for better behavior on mailing
  lists and bouncemail.

* New Makefile production to generate an RPM.

* The `no received' option of 3.4 is gone.  Instead, say `no envelope'. 
  This suppresses all attempts to extract an envelope address and route
  based on it.  If you set `no envelope' in the defaults entry it is possible
  to undo that in individual entries by using `envelope <string>'.

bugs --

* Yet another fix to the password-shrouding logic.

* Fix bug that screwed up IMAP mail reception in -v mode *only*.

There are 229 people on the fetchmail-friends list.

------------------------------------------------------------------------------
fetchmail-3.5 (Sat Feb 15 15:19:36 EST 1997)

features --

* The host that ETRN specifies is now set by the smtphost option.

* It is now possible to suppress Received line parsing in multidrop mode
  with a new `no received' per-server option.

* Major FAQ reorganization and additions.

* .poprc-style `user'-less entry now triggers a warning.

bugs --

* The counter referred to by the batchlimit option used to count not only 
  fetched messages but skipped ones.  This has been fixed.

* Compilation fixes for Kerberos V4 support and GNU glibc2 support.

There are 230 people on the fetchmail-friends list.

------------------------------------------------------------------------------
fetchmail-3.4 (Wed Feb 12 19:23:06 EST 1997)

features --

* Support for ESMTP ETRN extension.

* It is now possible to turn off option flags in individual server entries
  that had been turned on in a `defaults' entry.

* The code should now deal gracefully with headerless mail.

bugs --

* The bug that displayed incorrect sizes for POP3 connections has been fixed.

* Upped the %a option in the lexer file so SunOS 4.1.3 lex won't choke with a
  "Too Many Transitions" error.

* Size-ticker dots are now disabled when verbose is on.  This should eliminate
  some alarming but harmless "(message incomplete)" messages from the
  error-logging machinery.

* A core dump in save_str_pair() that only showed up on some systems has
  been fixed.

There are 223 people on the fetchmail-friends list.

------------------------------------------------------------------------------\

pl 3.3.2 (Mon Feb  3 12:59:33 EST 1997):
* Minor fixes to stripcr and password-shrouding logic.

pl 3.3.1 (Sun Feb  2 02:17:07 EST 1997):
* Fix incorrect stripcr processing
* Unapply a patch that broke error logging to files.

------------------------------------------------------------------------------\
fetchmail-3.3 (Sat Feb  1 15:15:13 EST 1997)

features --

* Whether or not carriage returns will be stripped on output is explicitly
  controllable with stripcr.

* fetchmail -v messages no longer reveal password lengths.

bugs --

* Correction to length-extraction code for servers that return (nnn octets).

* Correction to RF822 continuation code so it doesn't eat leading blank-led
  lines in the text.

There are 215 people on the fetchmail-friends list.

------------------------------------------------------------------------------
fetchmail-3.2 (Mon Jan 27 02:51:10 EST 1997)

features --

* Better error notification on IMAP select failure.

bugs --

* The code can now handle arbitrarily long address lists.

* Fix RFC822 parsing to strip comments at end of bare addresses.

* Explicitly strip CRs out of fetched mail.

* Corrections to 8BITMIME processing.

There are 207 people on the fetchmail-friends list.

------------------------------------------------------------------------------
fetchmail-3.1 (Fri Jan 24 12:45:18 EST 1997)

features --

* Forwarding is now done via ESMTP where possible.

* ESMTP 8BITMIME option is supported; when 8BITMIME is supported and the
  Content-Transfer-Encoding header is 7BIT or 8BIT, it is appended to the
  MAIL FROM command as a BODY option.

* ESMTP SIZE option is supported when using IMAP2bis or IMAP4.  This means
  messages too long for the local ESMTP listener will be rejected *before*
  they are passed to the ESMTP listener.

* IMAP code now detects IMAP4rev1 capabilities (RFC 2060) and uses them.
  (It will fall back to IMAP4 or IMAP2bis depending on what it sees.)

bugs --

* Compilation fixes for non-Linux machines.

There are 205 people on the fetchmail-friends list.

------------------------------------------------------------------------------
fetchmail-3.0 (Tue Jan 21 16:44:56 EST 1997)

features --

* `interface' and `monitor' options are now per-server.

* `batchlimit' option is now per-user.

* RFC822 header continuation for long address lists is is now handled properly.

* There is now a `nodns' option to suppress DNS checking of address hostname
  parts in multidrop mode (make sure your aka list is complete before you use
  this!).

* Options such as `nokeep' can now be written `no keep'.

* RPOP support is back by user request.

Note: The first two changes mean that older .fetchmailrc files using
the `set' syntax for these options will cause fetchmail to die with a
parse error at initialization time.  Conversion is trivial -- for
details, see the FAQ.

bugs --

* Stricter parsing of greeting message for the host name; eliminates some
  minor errors when using IMAP and the hostname is something like jet.es.

* --quit in root-daemon mode didn't work, fixed this.

* Ensure that default server parameters get properly zeroed out after each
  poll or skip statement in .fetchmailrc. 

* Arrange an EXPUNGE after each delete when using IMAP, so deletions get done
  OK even if there's a socket error before termination.

* Simpler and better header-rewrite code, fixing some weird cases where 
  it failed.  Thanks to Masafumi NAKANE <max@wide.ad.jp> and
  Carey Evans <c.evans@student.canterbury.ac.nz> for pointing out these
  problems.

* Handle zero-length messages properly; thanks to Bob Craycroft.

Note: the RFC subdirectory is no longer included with the distribution
(this cut its size in half!)  Instead, applicable RFCs are listed on the
manual page.

There are 201 people on the fetchmail-friends list.

------------------------------------------------------------------------------
fetchmail-2.8 (Sat Jan 11 15:48:33 EST 1997)

features -- 

* We now get the hostname used for progress messages from the server greeting.
  This means you'll get sensible-looking progress messages even when using
  ssh to redirect secure connections.

* Reorganized and improved man page.

* Mail header parsing now handles RFC822 escapes properly.

bugs --

* Stop netrc parser from complaining about blank lines.

* Add ssh recipe correction.

* Eliminate infinite-loop bug in defaults handling.

* Fixed some address-parsing bugs in rfc822.c:nxtaddr().

* 2.7 broke portability to Solaris.  Fix that.

There are 184 people on the fetchmail-friends list.

------------------------------------------------------------------------------
fetchmail-2.7 (Thu Jan  9 03:18:15 EST 1997)

features -- 

* New --syslog option by Dave Bodenstab.

* Automatic parsing of ~/.netrc for a mailserver password if necessary, thanks
  to Gordon Matzigkeit.

* Added preconnect option for initializing ssh connections.

* Added local-domains support for multidrop as requested by Pablo Saratxaga.

* More FAQ material on how and when to use --interface.

bugs --

* Fixed a minor bug introduced into From handling by 2.6.

* Fixed bug in SMTP forwarding of msg lines with leading dot.

* Fixed a bug that generated incorrect HELO for second and subsequent
  poll entries attached to the same SMTP host.

There are 177 people on the fetchmail-friends list.

------------------------------------------------------------------------------
fetchmail-2.6 (Fri Dec 27 12:42:56 EST 1996)

features -- 

* IMAP4 code now sets the server "seen" flag on each message if "keep" is on.

* New FAQ material on how to use --interface.

bugs --

* Dropped back to separate SockGets/SockWrite code with no attempt at
  stdio buffering -- we hope this will fix the Solaris peoples' problems.

* Fixed length-computation bug (apparently introduced in 2.3) that messed
  up IMAP deletes.

There are 169 people on the fetchmail-friends list.

------------------------------------------------------------------------------
fetchmail-2.5 (Mon Dec 23 04:18:54 EST 1996)

features -- 

* New --interface and --monitor options for Linux courtesy of George Sipe.

bugs --

* Replaced bug-prone setvbuf with setlinebuf.

* Moved lock file to ~/.fetchmail to eliminate various /tmp problems.

There are 165 people on the fetchmail-friends list.

------------------------------------------------------------------------------
fetchmail-2.4 (Sat Dec 21 05:24:44 EST 1996)

features -- 

* Add FAQ material on troubleshooting and working around SMTP connection
  failures.

bugs --

* Fixed a core-dump bug in MX processing that's been lurking there for ghods
  know how long.  It could never have been more than rare.

* Fixed a minor bug in Received processing.

* Restored compile-time portability to Solaris.

* Initial 2.4 said: "Force line-buffering on socket streams (Linux apparently
  defaults to this). This may fix some hang problems reported under Solaris."
  Unfortunately this "fix" triggers horrible lossage on long messages and had
  to be removed.

There are 166 people on the fetchmail-friends list.

------------------------------------------------------------------------------

features -- 

* Full IMAP4 support -- we now probe for IMAP4 capabilities and use 
  RFC822.PEEK when possible to avoid marking messages seen on the server
  before they are deleted.  This improves recovery from sendmail and
  dropped-connection errors.

* True stdio buffering of sockets at last, thanks to Cameron McPherson.
  This should be good for a significant throughput increase.

* Almost all error messages that might be emitted in daemon mode now go
  through the error() subroutine.  This is a first step towards allowing
  a daemon-mode fetchmail to use syslog.

* SIGUSR1 is now used for wakeup rather than SIGHUP.  This eliminates any
  possible confusion about fetchmail's behavior at logout time.

* Received line parsing for envelope addresses now matches MX as well as 
  canonical DNS addresses, making multidrop routing slightly more reliable.

* Added --fetchlimit option to limit number of messages fetched in a
  single poll.

bugs --

* Fixed a FreeBSD compilation glitch involving SIGCLD (thanks to
  Masafumi NAKANE).

* Added some port patches for NEXTSTEP.

* SIGCHLD used everywhere now, not SIGCLD (this was strictly a cosmetic bug).

* Prevent occasional hangs when fetchmail was terminated by signal.

There are 168 people on the fetchmail-friends list.

------------------------------------------------------------------------------
fetchmail-2.2 (Mon Dec  9 00:15:01 EST 1996):

features --

* If SMTP returns 571 (unsolicited mail refused) to a MAIL FROM, the
  address is excluded by the local sendmail's spam filter.  Drop the mail.
  (This is the only circumstance in which mail is thrown away.)

* The header your mailserver uses to convey envelope addresses is no longer
  wired to `X-Envelope-Header'.  You can now specify it with the `envelope'
  option in .fetchmailrc.  (This header is not RFC822 standard, and we have a
  report of an ISP using X-Frontier-To).

bugs --

* Fixed a startup-time core dump introduced by 2.1's aka-list feature.

* Fixed a bug in non-implicit mode (poll specified host), also due to aka.

* Various minor portability fixes for Suns.  Adding #include <errno.h>
  in fetchmail.c was the most significant one. 

* Avoid using -lresolv when possible, some Linux versions are badly broken.

* Fix error in MX record handling that was causing multidrop problems.

* Disable daemon SIGCHLD handler while an MDA is running, to avoid snafus.
  Thanks to Dave Bodenstab <imdave@synet.net> for spotting this obscure bug.

156 people on the contact list.

------------------------------------------------------------------------------
fetchmail-2.1 (Thu Nov 28 11:07:48 EST 1996):

features --

* Added FAQ file.

* Try to pass envelope From to the listener so that logging and procmail
  processing works right.  If that fails, fall back on calling-user.

* Added `set logfile = ' option to rc syntax.

* We now use X-Envelope-To headers and parse the Received lines.  If
  X-Envelope-To is found, OK; otherwise we look for a `Received for' line;
  either is treated as a true envelope address.  If neither of these are
  found we go to the To/Cc/Bcc header addresses.

* Added `*' as a wildcard option for multidrop to ... here.  This will allow
  names to be local names to be passed through from a multi-drop box on
  a mailserver 

* Added an `aka' option to allow users to declare mailserver aliases at start
  of run, so DNS does less work.  During a run, cache host matches on the
  aka list so no potential alias has to be DNS-checked more than once.  
  A server being polled explicitly may be referred to by any of its aliaseses.

bugs --

* Nalin Dahyabhai's fix patch for MIT Kerberos V4 support.

* Fixed a fencepost error in the APOP code that was causing a core dump.

* Skip flag wasn't getting reset on poll hosts following a skipped one.

* Include remote name in saved UID mappings so multiple POP accounts on
  the same server won't get their UIDs confused.

------------------------------------------------------------------------------
fetchmail-2.0 (Mon Nov 18 00:32:17 EST 1996):

* Fix typo in setitimer call setup that caused obscure bugs under FreeBSD.
* Accept Apparently-To if there is no To header.
* Include Cameron McPherson's patch for handling multi-line SMTP responses.
* Don't try to feed listener the header From any more.

pl 1.9.9 (Mon Nov 11 10:40:14 EST 1996):
* Accept Resent-From & Apparently-From a la RFC822.
* Include file fixes for Solaris 2.5 and FreeBSD 2.2.
* Improved error notification on SMTP and no-matching-local-address errors.
* Delivery to multidrop mailboxes now always aborts on DNS errors.
* Batch limit option prevents long delivery delays on smail/qmail.
* Configuration now handles -lresolv and non-Linux bind libraries correctly.

pl 1.9.8 (Wed Nov  6 16:40:34 EST 1996):
* Don't append spurious NUL to the headers, qmail actually notices it.
* Fatal bug in multidrop code fixed.
* Fail cleanly, instead of core-dumping, on mail lacking an RFC822 From line.
* Don't try to keep the SMTP socket open across poll cycles.

pl 1.9.7 (Fri Nov  1 10:02:34 EST 1996):
* %s is back.  Seems some popular MDAs actually choke on name arguments.
* We can handle responses longer than the socket atomic read length now.

pl 1.9.6 (Thu Oct 31 00:07:23 EST 1996):
* Make rewrite option handle multiple comma-separated local names correctly.
* Fix yet another fatal error in MDA argument list construction.
* Reset timeout every time input is received.
* Correct localname detection when --norewrite is on.

pl 1.9.5 (Tue Oct 29 20:07:41 EST 1996):
* Added -N, --nodetach option for debugging purposes.
* Use interval timers for poll-interval sleep and nonresponse timeout.
* fetchmail -q no longer parses the configuration file.
* Configuration file grammar is slightly cleaned up and improved.

pl 1.9.4 (Mon Oct 28 20:58:48 EST 1994):
* Correct status interpretation in closemailpipe() (thanks to Neil Harkins).
* Tweak SMTP forwarding to only open one listener per SMTP host in daemon mode.

pl 1.9.3 (Sun Oct 27 22:35:33 EST 1996):
* Handle nested parens in RFC822 comments.
* More gcc -Wall cleanup.
* Improved installation docs.
* Don't query DNS on startup unless needed for Kerberos or multidrop mailboxes.

pl 1.9.2 (Sun Oct 27 01:10:30 EST 1996): 
* Fix initialization-time core dump when running as root
* Fix fatal error in MDA argument-list construction.

------------------------------------------------------------------------------
fetchmail-1.9 (Fri Oct 25 23:02:26 EDT 1996):

We've hit the century mark -- exactly 100 people on the fetchmail-friends list.

features --

* FEATURE FREEZE IS NOW IN EFFECT!  No new features until after 2.0.  Thanks
  to everybody who contributed ideas and criticism.

* It is now possible to specify multiple local recipients by giving a list
  of names following "to" or "is".  Each local recipient is checked for in the
  To:, Cc: and Bcc: headers of each message; if a match is found, the message
  is sent to that local recipient.  This makes it possible to do mailing
  lists and multidrop mailboxes.  See the man page for details (and note
  the caveat in the BUGS AND KNOWN PROBLEMS section).

* It is possible to specify a size limit for retrieved messages.  I resisted
  doing this because I don't want fetchmail to be in the filtering game, but
  too many Europeans begged for it because their telecomms monopolies are
  price-gouging them on per-second phone charges.  I will ignore, or be
  extremely rude to, anyone who takes this feature as a license to beg me
  for kill files or any other form of content-based filtering.  Use 
  procmail on your server if you want that.

* If you use an MDA, the internal changes to support multi-drop mailboxes
  require that you *remove* the %s at the end of your MDA string.  Local 
  delivery addresses will be appended to the end of the command in the
  obvious way.

* The first message from a query now includes the number of old messages
  when this can be determined (that is not under POP2).

* POP3 UID support really works now.  I make rude noises at the POP3 mavens
  who forced us to this with RFC1725, but thank Al Longyear <longyear@sii.com>
  for fixing and verifying my slightly buggy implementation.

* Kerberos V4 support ditto.  Thanks to Chris Hanson <cph@martigny.mit.edu>
  for this feature.

* When there's a daemon fetchmail in background, running fetchmail in
  foreground without --quit now tries to wake the daemon and force it
  to poll immediately.

* Add option to set server nonresponse timeout.

* Password is no longer displayed in verbose mode.

* You may use C-like escapes to embed non-printables in passwords and other
  strings.  Fetchmail -V will display them in a printable form.

* Program now tries to set itself to the ID of the local user before
  running an MDA, and reset to root afterwards.  This will work on
  any system with seteuid(2), including Linux and the BSDs.

bugs --

* Default user name to deliver to is now the calling user, unless
  program is running as root in which case it is the remote user name
  (default can be overridden with an `is' or `to' declaration).
  In versions up to 1.7 it was the calling user; in 1.8 the remote
  user ID.  This created some confusion.

* Accept RFC822 headers with a tab after the colon.

* You now see a "skipping" message for each message not retrieved.

* --keep no longer overrides --flush.

* Rewrite "To: jrh (J. Random Hacker)" correctly.

* Find "nnn octets" anywhere on a POP3 server's RETR response line.

* Fixed various bugs in --check.  It now reports PS_SUCCESS only if
  there is new mail waiting.

* Under Linux, if fetchmail is run in daemon mode with the network
  inaccessible, each poll leaves a socket allocated but in CLOSE state
  (this is visible in netstat(1)'s output).  These sockets aren't
  garbage-collected until fetchmail exits.  When whatever kernel table
  is involved fills up, fetchmail can no longer run even if the network is up.
  To avoid this, fetchmail now commits seppuku after some number of
  unsuccessful socket opens.

* Don't try using FLAGS.SILENT, some allegedly IMAP2bis servers seem to
  choke on it.

------------------------------------------------------------------------------
fetchmail-1.8 (Fri Oct 11 15:08:10 EDT 1996):

features --

* Use kill(0, pid) to make lock handling a bit smarter (thanks to Johan
  Vromans <JVromans@squirrel.nl> for the suggestion).

* Arrange for timeout of client after 5 minutes if connection to server is 
  dropped (thanks to Gaspar Sinai <gsinai@gol.com>).

* All pretensions to RPOP support have been dropped.  Yes, this is a feature,
  RPOP is very vulnerable to spoofing!  Use APOP instead.

* Normal start-of-read message now displays the byte (excuse me, "octet")
  size of the message.  Yes, 3schwend, you can stop noodging me now :-).

* Normal progress notifications now take only 1 line per message, not 2.

* Linux packagers: building fetchmail now generates an RPM specfile for it.

* Kerberos V4 support via KPOP protocol (thanks to Chris Hanson).

* New --check option for asking server whether there is mail without
  actually retrieving or deleting it.

* UID support is back by popular demand.  Bletch.

* Permit spaces in IMAP passwords (ship them as quoted strings).

bugs --

* Fix buggy getopt specification of P and p options.

* Fix uninitialized-variable bug that was hanging second IMAP queries.

------------------------------------------------------------------------------
fetchmail-1.7 (Tue Oct  8 11:32:44 EDT 1996):

features --

* Noise words for rcfile syntax make English-like syntax possible.

* Make configure more GNUish; it understands --prefix and other standard
  autoconf options now (see INSTALL for details)

* Better documentation of the new .fetchmailrc extensions and the slightly
  stricter rules for ordering options.

* Expanded installation instructions including how to test for correct
  operation without losing mail to misconfigured MDAs, alias loops, etc.

bugs --

* You may have to rearrange the order of options in your .fetchmailrc.
  The grammar for the new multiple-user syntax requires that server 
  options (protocol and port) come before any user options.

* Fixed core dump bug that was screwing configurations with no .fetchmailrc.

* Fixed broken 'p' option.

* `norewrite' and `rewrite' in .fetchrc were the inverses of what they
  should have been (but the rewrite default was set correctly).

------------------------------------------------------------------------------
fetchmail-1.6 (Sun Oct  6 20:55:09 EDT 1996):

features --

* You can now have multiple entries for the same server but different
  users, and the right thing will happen (each user's mailbox will
  be queried).  Even better, you can now specify multiple users in a
  single server entry.

* Restore --mda, seems some people either can't run a port 25 listener
  due to bizarre dynamic-SLIP problems, or won't for security reasons.

* When delivering to an MDA, print error and die (before deleting the message!)
  if the MDA returns nonzero status.  Better safe than sorry.

* If fetchmail is called through a link named `popclient' it will look in
  ~/.poprc for a run control file.  Unless that file includes the deleted
  options limit and localfolder this should actually work.

bug fixes --

* Makefile fixes for correct linking on Sparcs and avoiding duplication of
  the md5 files (leading to harmless install-time error messages).

* Fix a bonehead coding error in pop3_delete() that was masked by the
  Intel register architecture.  *blush*  Thanks to Jay Anderson
  <anderson@optical.bms.com>.

* Fix bug that prevented SMTP from being specified on the defaults line.

* Allow program to generate correct lockfiles when USER is undefined
  (i.e. under zsh).

* Allow program to run with no .fetchmailrc file again.

------------------------------------------------------------------------------
fetchmail-1.5 (Thu Oct  3 04:35:15 EDT 1996):

* Naturally, my decision to announce 1.4 on comp.os.linux.announce 
  immediately caused the code to manifest its first real bug --
  a core dump when the "From:" header is spelled "from:" (all lower
  case).  Fixed.

* Update and expansion of NOTES.

* The --all and --flush flag validity checks move to driver.c.

------------------------------------------------------------------------------
fetchmail-1.4 (Wed Oct  2 09:22:37 1996):

* More man page improvements.

* Lexer changes to work around bison's "feature" of silently ignoring 0-value
  tokens (caused options nokeep, norewrite, nofetchall, noskip to be no-ops).

------------------------------------------------------------------------------
fetchmail-1.3 (Tue Oct  1 05:49:49 1996):

* Significant man page improvements.

* Escapes for newlines in .fetchmailrc are now optional.

* Kill off -2 and -3 options, redundant popclient remnants.

* IMAP code simplification and robustification.  Use FETCH FLAGS to find
  seen messages.  Code should now work even if unseen messages are 
  interspersed with seen ones, and even if messages are appended to the
  mailbox during the run.

------------------------------------------------------------------------------
fetchmail-1.2 (Sat Sep 28 15:40:50 EDT 1996):

* The great option massacre.  Remove --stdout, --limit, --local, --mda.
  We get a significant code and complexity shrinkage this way (a lot of the
  configuration machinery goes away too).  These things are your MDA's job.
  (This also kills off the lose-mail-on-disk-full bug, which I've never 
  seen but two users reported.)

* Link APOP support by default.

* Fix embarrassing Makefile bug.

------------------------------------------------------------------------------
fetchmail-1.1 (Sat Sep 28 09:21:10 EDT 1996):

* In POP3, don't send LAST if STAT shows count of waiting messages to be zero.

* Document APOP better, we know it works now.

* Lose the .fetchids file and give up on POP3 UIDs, they're a dead loss.

------------------------------------------------------------------------------
fetchmail-1.0 (Thu Sep 26 11:59:38 EDT 1996):

* SMTP forwarding and header-rewrite features work with POP2 now.

* Stricter RFC822 conformance, so SMTP to qmail works.  Thanks to
  Cameron MacPherson <unsound@oz.net> for these changes.

* The program is quieter but more informative now (suppress printing of
  server greeting message; add the server host being queried to the
  message count information line).

* Add `skip' option to make it easier to set up test entries.

* Name change (it ain't just for POP any more).

==============================================================================
popclient-3.2 (Mon Sep 23 13:29:46 EDT 1996):

* RPOP support (coded at a user's request but untested).

* Ported to QNX (see the Makefile).

* Add code by Michael Schwendt <3schwend@informatik.uni-hamburg.de> for
  improved sizeticker.

* Improved RFC822 parsing (thanks to Rob Funk).

* Move the per-user lockfile to /tmp so it gets cleared at reboot time.

* Warn users that running concurrent instances of popclient is a bad idea.

* Try USER and HOME to set defaults before going to the password file.
  This should work better in Sun NIS environments.

popclient-3.1 (Thu Sep 12 15:45:25 EDT 1996):

* MDA arguments are now dumped when using the -V option.

* Sendmail delivery from background seems to work now.

* We have IMAP2bis/IMAP4 support.

* Code now autoprobes for a POP3, IMAP, or POP2 server if no protocol is
  specified.

* SMTP forwarding support.  Thanks to Harry Hochheiser <harry@tigger.jvnc.net>
  for this simple but clever idea.  It's now the default delivery mode.

* If no UNIX From line is found, popclient will now synthesize a correct
  line from the RFC822 From line.

* It is now possible to specify the host TCP/IP port number to connect to.

popclient-3.05 (Thu Aug 22 22:59:04 EDT 1996):

* Experimental support for RFC1725-compliant POP servers with the UIDL
  command and without LAST.

popclient-3.04 (Wed Aug 21 00:22:44 EDT 1996):

* Logfile option works.

popclient-3.03:

* Minor bug fixes for password querying and redirection to stdout.

popclient-3.02 (Fri Jul 19 11:37:56 EDT 1996):

* Correct buggy processing of nokeep/noflush/fetchall.

* Fix buggy -mda option processing.

* Added -N/--norewrite option.

* Delivery via sendmail now works in non-daemon mode.

popclient-3.01 (Mon Jul  1 13:33:51 EDT 1996):

* Fixed a lexical analyzer bug in quoted-string processing.

* Fixed a bug in dump_options that caused username to be displayed incorrectly.

* The lock assertion code was in the wrong place relative to the daemonize()
  call.  

popclient-3.0 (Fri Jun 28 11:33:34 EDT 1996):

Eric S. Raymond <esr@thyrsus.com> hacked extensively on 3.0b6 and took over
the package with the consent of Carl Harris, the original implementor.
Some of the 3.0 feature additions were inspired by Sean Oh's fetchpop 1.8
code, and a few use code directly lifted from fetchpop. Here are my (Eric's)
change notes:

CONFIGURATION AND BUILDING

* The autoconfigure script incorrectly assumed that all Linuxes use
  /usr/bin/deliver.  Under Linux it now checks for both /usr/bin/delivermail
  and /bin/mail.

* I added a distribution-maker production to Makefile.in.

OPTIONS AND COMMAND LINE

* I have removed the -p command-line option. Given that there's a run control
  facility there is no excuse for encouraging users to put plaintext passwords
  in scripts which might be readable.

* Calling popclient with no arguments now causes it to query or operate
  on every host in the run control file.

* I have made --version more useful by having it dump the computed
  connection options for each server specified.

* The user can now explicitly set an MDA (such as procmail) with the
  new option -m or -mda.  Various possible MDAs are listed on the man page.

POPRC FILE SYNTAX

* The run control file lexer now supports "-enclosed strings which may 
  contain whitespace.

* I added a --yydebug option to enable run control parser debugging at 
  runtime if the parser was generated with --debug.  It's not documented.

* You may now have a `defaults' entry in the run control file which sets 
  overrideable values for other entries.  See the man page for details.

* It is now possible to set keep, flush and fetchall in your run control
  file.

* Fixed incorrect numbering of source lines in run control file parse error
  messages.

* The configure.in specification no longer uses the obsolete AC_TRY_COMPILE
  macro (it uses AC_TRY_LINK instead).

MAILBOX LOCKING

* I have added mandatory locking of mailbox files where supported.
  This will cover Linux systems, in particular.

* The default behavior is now to do lock-protected append on the user's
  system mailbox rather than using delivermail or some other MDA.
  (This is a performance hack.)

* The autoconfigure script now looks for standard mail locations.  The
  default mail delivery agent is used only if it can't find a mail spool
  directory in the standard places.

FUNCTIONAL ENHANCEMENTS

* When using POP3, message headers are edited so that replies won't foo up.
  Anything that looks like a mail ID local to the POP host gets @ and the
  pop servername attached to it before being appended to the user's
  mailbox or passed to an MDA.

* I have implemented daemon mode.

* I have added a lock check to ensure that there is only one popclient
  running per user, and a --quit option to kill the currently running
  one.

DOCUMENTATION

* All changes and feature additions have been tested in actual use and are
  documented on the man page.

* I have turned the comments in the sample run control file into a new manual
  section documenting the file format.

MISCELLANEOUS BUG FIXES

* I fixed some de-initialization bugs in pop2.c and pop3.c that led to
  fd leaks (these became painfully obvious when I tested daemon mode!).

* I've fixed the flaky parser error messages. They turned out to be due 
  to a misdeclaration of yytext.

These are Carl Harris's change notes from previous releases:

3.0b5
o       "From " header fix in pop2.c and pop3.c
o       Surpress "..." output when --stdout option specified in pop3.c

3.0b4
o       alloca fix.
o       various diagnostic/informational message fixes.

3.0b3
o       Support for retrieving only new messages from maildrop when
        using POP3.  
o       Support for retrieving only the first n lines of each message
        when using POP3.
o       APOP authentication support.
o       Buffered socket input.

3.0b2
        This is a "new features" release.
o       support for .poprc file.
o       GNU-style long options.
o       fixed passwords appearing in 'ps' output
o       support for multiple servers on one command line

3.0b1
        This is mostly a test of the autoconfigure integration.
Among the functions performed by the new configure script, is
the ability to detect known system types, configures the mail
delivery agent (MDA) correctly.  This should permanently solve
the problem of using something other than an MDA for mail
delivery (which continues to plague Linux slackware 1.2.9).
For this beta, please check the values of MDA_PATH and MDA_ARGS
carefully.  They should match the values found in your
sendmail.cf file on the line which begins with "Mlocal".

        Other changes from popclient version 2.21:

o       no longer uses getpass() from the C library.  The
        internal getpassword() function allows the use of long
        passwords.

o       integrated GNU getopt() for long options.  Long option  
        names will appear in a future beta.

o       Several compiler warnings fixed.

o       Fixed problems related to missing include files in
        Solaris port.
