Fetchmail Bugs and To-Do Items

+

Note that there is a separate TODO.txt document of +different content than this.

+

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.

-

Feature request from "Ralf G. R. Bergs" "When -fetchmail downloads mail and Exim+SpamAssassin detecs an incoming -message as spam, fetchmail tries to bounce it. Unfortunately it uses -an incorrect hostname as part of the sender address (I've an internal -LAN with private hostnames, plus an official IP address and hostname, -and fetchmail picks the internal name of my host.) So I'd like to have -a config statement that allows me to explicitly set a senderaddress -for bounce messages." +

Serious

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.

+

Let IMAP code use UID and UIDVALIDITY rather than relying on flags +that everyone can alter.

POP3 hang when polling mail with NUL char that is rejected (David +Greaves) https://lists.berlios.de/pipermail/fetchmail-devel/2004-October/000154.html

It has been reported that multidrop name matching fails when the name to be matched contains a Latin-1 umlaut. Dollars to doughnuts @@ -52,42 +42,79 @@ 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.

Alan Munday suggests message change MULTIDROP without ENVELOPE:

+
+fetchmail: warning: MULTIDROP configuration for pop.example.org requires the envelope option to be set!
+fetchmail: warning: Check ENVELOPE option if fetchmail sends all mail to postmaster!

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 +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).

+

Maybe refuse multidrop configuration unless "envelope" is _explicitly_ +configured (and tell the user he needs to configure the envelope +option) and change the envelope default to nil. This would +prevent a significant class of shoot-self-in-foot problems.

-

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.

+

Given the above change, perhaps treat a delivery as "temporarily +failed" (leaving the message on the server, not putting it into +.fetchids) when the header listed in the "envelope" option is not +found. (This is so you don't lose mail if you configure the wrong +envelope header.)

NOTE that the current code need optimization, if I have +unseen articles 3 and 47, fetchmail will happily request LIST for +articles 3...47 rather than just 3 and 47. In cases where the message +numbers are far apart, this involves considerable overhead - which +could be alleviated by pipelining the list commands, which needs +either asynchronous reading while sending the commands, or knowing the +send buffer, to avoid deadlocks. Unfortunately, I don't have the time +to delve deeper into the code and look around.

+ +

Note that such a pipelining function would be of universal use, so it +should not be in pop3.c or something. I'd think the best approach is to +call a "sender" function with the command and a callback, and the sender +will call the receiver when the send buffer is full and call the +callback function for each reply received.

+

See the ESMTP PIPELINING RFC for details on the deadlock avoidance +requirements.
