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.
IDLE is not fully implemented. Fetchmail does not time out the idle
connection every 30 minutes or less as required by RFC2177. Some
servers (including UW IMAPD compiled without the
MICROSOFT_BRAIN_DAMAGE option, as is the default) will drop the
connection after 30 minutes, resulting in a spurious socket error in
your logs and no mail being picked up until the next poll cycle.
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.
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).
John Summerfield suggests that specifying a localname containing @
ought to be treated as an smtpname option, with the domain part
removed for other purposes such as local-address matching.
The Debian bug-tracking page for fetchmail lists other bug reports.
