                       Fetchmail Bugs and To-Do Items

   I try to respond to urgent bug reports in a timely way. But fetchmail
   is now pretty mature and I have many other projects, so I don't
   personally chase obscure or marginal problems. Help with any of these
   will be cheerfully accepted.

   Using LMTP alias with a local name that is not a full name fails
   horribly (the LMTP port never gets stripped off the name). The UIDL
   code seems rather broken. It's a nasty swamp. Somebody who actually
   uses it should fix it -- every time I try I seem to make things
   worse....

   POP3 can't presently distinguish a wedged or down server from an
   authentication failure. Possible fix: after issuing a PASS command.
   wait 300 (xx) seconds for a "-ERR" or a "+OK" . If nothing comes back,
   retry at the next poll event and generate no errors. If we get an -ERR
   then log an authentication failure.

   SMTP authentication a la RFC 2554 ought to be supported. The Exim
   reference has a whole chapter on this topic.

   It has been reported that multidrop name matching fails when the name
   to be matched contains a Latin-1 umlaut. Dollars to doughnuts this is
   some kind of character sign-extension problem. Trouble is, it's very
   likely in the BIND libraries. Someone should go in with a debugger and
   check this.

   In the SSL support, add authentication of Certifying Authority (Is
   this a Certifying Authority we recognize?).

   Laszlo Vecsey writes: "I believe qmail uses a technique of writing
   temporary files to nfs, and then moving them into place to ensure that
   they're written. Actually a hardlink is made to the temporary file and
   the destination name in a new directory, then the first one is
   unlinked.. maybe a combination of this will help with the fetchmail
   lock file."

   Move everything to using service strings rather that port numbers, so
   we can get rid of ENABLE_INET6 everywhere but in SockOpen (this will
   get rid of the kluge in rcfile_y.y).

   The Debian bug-tracking page for fetchmail lists other bug reports.
