4 - audit if there are further untrusted data report_*() calls.
5 - Debian Bug #475239, MIME decoder may break up words (need to quote results)
6 - put bare IP addresses in brackets for SMTP (check if there are RFC
7 1123/5321/5322 differences)
8 - Debian Bug #531589: fetchmail ignores SIGUSR1 in idle mode.
9 - Fix further occurrences of SMTP reply code handling:
10 - for proper smtp_reponse caching of multiline codes (there are some)
11 - for stomping over control characters.
12 - check if smtpname and smtpaddress in particular work as advertised,

15 - virtual domain DOCUMENTATION (rewriting @example.com to
16 @virtual.example.com possible? Joost Roeleveld, thread "Fetchmail with
17 Postfix virtual users" around 2009-09-23 on fetchmail-users@).
20 - SockOpen sometimes exits with errno == 0, confusing users (found with
21 Google RealTime on Twitter)
22 - make sure the man page completely lists all options (f. i. sslcertpath) in
24 - allow \Deleted without \Seen, rf.

26 - document IMAP4 ACL requirements
27 - CRYPTO: log configured server name on certificate mismatch (perhaps pay
28 attention to via entries and stuff like that)
29 - CRYPTO: http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=432618
30 * write a table of combinations of TLS/SSL options
31 - add To: header to warning mails (authfail for instance)
32 - Fix TOCTOU race around prc_filecheck*
33 - Read CAPABILITY from greeting if present, saves one round trip.
34 - Check if LAST argument is properly validated against message count.
35 - add Message-ID: header and other SHOULD headers to warning mails?
36 - report actual SMTP error with "SMTP listener refused delivery", sugg.
37 Richard Brooksby, fetchmail-users 2010-04-06.
40 - find a better replacement for sscanf parsing - we don't usually
41 detect errors in format strings such as "* %d FETCH " because we don't
42 check if the FETCH is (a) present, (b) consumed.

44 => fetchmail: support utf-8 encoding in log file
45 Revisit http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=400719
46 => syslog messages are localised
47 http://lists.debian.org/debian-devel/2006/11/msg01068.html
48 - when logging to syslog, disable locale?
49 - Get rid of peeking in socket.c? MSG_PEEK seems non-portable.
50 - revise ticker, and add something like .........20%.... ... 100%
54 - Convert POP3 UIDs to X-UIDL?
55 - fetch IMAP message in one go (fetchmail-devel by Adam Simpkins
56 <simpkins@cisco.com> around Nov 2nd)?
59 - Properly free host/user entries (through C++ class instantiation and destructors...)
60 - Remove stupid options, such as spambounce, or deferred bounces for anything
62 - Do not ever guess envelope from content headers such as To:/Cc:/Resent-To: or
64 - Replace sscanf/fscanf by functions that do range checking
65 (strtol/strtoul), and make arguments unsigned long.
67 - use PS_PROTOCOL for pre-/post-connect command failures - 6.3 uses
68 PS_SYNTAX, and that's not necessarily the case. At least if the
69 command terminates with a signal, we should report PS_PROTOCOL.
70 - revisit maximum allowed rcfile permissions, fix inconsistency
71 (silently allowing g+x).
72 - make UID code more efficient, parsing is O(n^2), should be no worse
73 than O(n log n), lookup is O(n), should be O(log n).
74 * Idea for C: use <search.h> tfind/tsearch. Need to split idlist up
75 so it only keeps the ids, and use an array to track status.
76 - help systematic debugging
77 - by making logging more strict (Postfix's msg_* as example??)
78 - by adding a --loggingtest or something that emits
79 a set of test log messages at various severity levels, in order to
80 make sure people get complete logs.
81 - by adding messages where fetchmail stuffed its output.
82 - Debian Bug #454291 fetchmail --quit: should check, that pid file
83 really contains pid of fetchmail process (Dmitry Nezhevenko)
85 - feature to skip first N or all messages upon first download, or fetch
87 - download only messages whose headers match a filter (by Toby, Usenet

90 - feature request by Daniel Goering <g_daniel@gmx.net> on
91 fetchmail-devel 2007-11-15: populate .fetchids from current messages.
92 (it'll probably be useful to limit this to "all but the 10 latest" or
93 "all before date this-and-that")

95 "Deleting fetchids file" vs. POP3 - probably unneeded if we use IMAP UIDs.
96 - CRYPTO: change SSL/TLS UI incompatibly, making it easier to use
97 - CRYPTO: allow selection of SSL/TLS Ciphers
98 - CRYPTO: perhaps switch to libgsasl and libgnutls (which doesn't talk SSLv2,
99 but we should abandon that anyways).
100 - CRYPTO: perhaps port to NSS? Check license and features and required procedure
101 changes. - Redhat Bugs #333741 (crypto consolidation), #346891 (port fetchmail to NSS)
102 - CRYPTO: make the SSL default v3 (rather than v23).
103 - CRYPTO: remove sslfingerprint? too easily abused (see NEWS)
104 - CRYPTO: force sslcertck
105 - CRYPTO: by default forbid cleartext or other compromising password
106 schemes over insecure connections?
107 - put more hints to the FAQ (should we call it FGA?) as first support place
108 - make sure we print socket error messages such as connection reset by
109 peer to hint users the problem is not in fetchmail
110 - require envelope option for multidrop ; if not found in header, defer message?
111 - > b) When the envelope header is specified, but it isn't found, a
112 > warning is logged and the mail is forwarded to the postmaster
113 > ("WARNING: Envelope header $HEADER found, cannot identify the
114 > recipient. Forwarding to the postmaster")
115 Rob MacGregor 2007-03-16 Patch to the man page, fetchmail-devel@
116 - integrate Isaac Wilcox's test rig
117 - look at Tony Earnshaw's .spec file
118 - look at Gentoo patches
119 - remove dead replacement functions: strdup (Andreas Krennmair), ...
120 - more SMTP/LMTP error detail on message rejections even outside verbose mode.
121 Ian D. Allen, fetchmail-users. Two messages with examples.
122 What goes here? fetchmailrc location, server, port, user, folder, anything else?
123 - see if "AUTH SSH" can be made to work for POP3
124 - revisit BerliOS patches
125 - check recent list mail
126 - check Debian BTS and other bug trackers
127 - better logging (log all headers, log forward destination + method)
128 - check strict envelope N Received parsing,
129 see mail from Admin Att on fetchmail-users
130 - 6.3.4-pending-deletes.patch
131 - fetchmail -s with running daemon complains rather than silently
133 - send warning message when connection fails?
134 - check FAQ O5 - do we really prefer From: over envelope?!?
135 - add code to allow safe authentication schemes if TLS fails
136 - make APOP an authenticator, integrate with regular auto authentication
137 but stuff it at the end
138 - allow forcing RETR (RETR vs. TOP, fetchmail-users, drbob 2008-01-11)
140 - make logfile more useful (redirect not only in daemon mode)
141 - close/reopen logfile on certain signals (for newsyslog/logrotate
143 - for virtual mapping, we don't currently support local user aliases or
144 regexp matching with replacement. This would be useful for hosting
145 several virtual domains in one multidrop mailbox, as in
152 some@one.example maps to bob-one-some@serverdomain
153 another@two.example maps to bob-two-example@serverdomain
155 we can strip the bob-*, but but we don't support domain catchalls
156 here, and we cannot currently delegate or rewrite the remaining
157 one-* or two-* users in a useful way. All local parts of the upstream
158 domains must be known and mapped in the configuration file.
159 (See fetchmail-users, Michelle Konzack, 2009-05-03, "4 multidrop but one
160 destination server" and followup)
162 This probably entails some form of extended user mapping inside
163 fetchmail, for map_name() in transact.c, and possibly
164 find_server_names() ibidem.
165 - more verbose diagnostics, what, why, how, ... (what does fetchmail do, what
166 does it expect, what does it get instead, what does that mean, how can the
167 user fix it; references to the manual)
171 - Add info whether Keywords are global, server or user keywords
172 - consolidate multidrop documentation
173 - HOWTO (on configuration, and on SSL in particular)
