+Note that there is a separate todo.html with different content than this.
+
+soon - MUST:
+- blacklist DigiNotar/Comodo hacks/certs, possibly with Chrome's serial#
+ list?
+- check if wildcards from X.509 are handled as strictly as required by
+ the RFCs.
+- audit if there are further untrusted data report_*() calls.
+- Debian Bug #475239, MIME decoder may break up words (need to quote results)
+- put bare IP addresses in brackets for SMTP (check if there are RFC
+ 1123/5321/5322 differences)
+- Fix further occurrences of SMTP reply code handling:
+ - for proper smtp_reponse caching of multiline codes (there are some)
+ - for stomping over control characters.
+- check if smtpname and smtpaddress in particular work as advertised,
+ thread "Fetchmail with Postfix virtual users" around 2009-09-23 on
+ fetchmail-users@, by Joost Roeleveld and Gerard Seibert.
+- virtual domain DOCUMENTATION (rewriting @example.com to
+ @virtual.example.com possible? Joost Roeleveld, thread "Fetchmail with
+ Postfix virtual users" around 2009-09-23 on fetchmail-users@).
+
+soon - SHOULD:
+- support NIL and strings where they are alternatives to literals
+- Debian Bug #531589: fetchmail ignores SIGUSR1 in idle mode.
+ seems non-trivial to fix: in imap_idle(), we wait for untagged
+ responses, and may be deep in SSL_peek -- and that restarts the
+ underlying blocking read() from the socket, so we never break out of
+ the SSL_peek() with SIGUSR1.
+- add repoll for all kinds of auth failures
+ (requires framework to track which auth failed in auto mode)
+- SockOpen sometimes exits with errno == 0, confusing users (found with
+ Google RealTime on Twitter)
+- make sure the man page completely lists all options (f. i. sslcertpath) in
+ the tables.
+- allow \Deleted without \Seen, rf.
+ http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=466299
+- document IMAP4 ACL requirements
+- CRYPTO: log configured server name on certificate mismatch (perhaps pay
+ attention to via entries and stuff like that)
+- CRYPTO: http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=432618
+ * write a table of combinations of TLS/SSL options
+- add To: header to warning mails (authfail for instance)
+- Fix TOCTOU race around prc_filecheck*
+- Read CAPABILITY from greeting if present, saves one round trip.
+- Check if LAST argument is properly validated against message count.
+- add Message-ID: header and other SHOULD headers to warning mails?
+- report actual SMTP error with "SMTP listener refused delivery", sugg.
+ Richard Brooksby, fetchmail-users 2010-04-06.
+
+soon - MAY:
+- find a better replacement for sscanf parsing - we don't usually
+ detect errors in format strings such as "* %d FETCH " because we don't
+ check if the FETCH is (a) present, (b) consumed.
+- http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=471176
+ => fetchmail: support utf-8 encoding in log file
+ Revisit http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=400719
+ => syslog messages are localised
+ http://lists.debian.org/debian-devel/2006/11/msg01068.html
+- when logging to syslog, disable locale?
+- Get rid of peeking in socket.c? MSG_PEEK seems non-portable.
+- revise ticker, and add something like .........20%.... ... 100%
+ (suggested by Yue Wu)
+
+questionable:
+- Convert POP3 UIDs to X-UIDL?
+- fetch IMAP message in one go (fetchmail-devel by Adam Simpkins
+ <simpkins@cisco.com> around Nov 2nd)?
