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). + + + +

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! ++ +
Feature request from "Ralf G. R. Bergs" <rabe@RWTH-Aachen.DE> "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."
+ +In the SSL support, add authentication of Certifying Authority +(Is this a Certifying Authority we recognize?).

+ +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.
+ +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.)
+ +Matthias Andree writes:
+ +++ +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.
