Re: [Fetchmail-users] Fetchmail suddenly downloading the same messages over and over

[Matthias A. <mat...@gm...>]

Greetings,

Rick has sent me verbose traces off-list, and they show that fetchmail
6.3.26 talks "LAST" with the server, but not UIDL, so I presume any
.fetchids are from other accounts.

Rick, I propose, as a band-aid, to try the --uidl option on the command
line, or uidl in the rcfile, either one should be sufficient to try and
enforce the use of UIDL instead of LAST.

I haven't yet followed the fetchmail code paths because "LAST" is hardly
used and I don't recommend it, and I need some quality time to debug
that - and note that LAST has also been pulled from the standard¹
(because it gets confused and can cause clients to skip mail when a
second other client accesses the same mailbox), but chances are that
somewhen in the late 6.2 or in the 6.3 phase the LAST code has
regressed. I will remove it from one of the future fetchmail versions
anyhow, and to be honest I'll only do a 6.3.26.1 with that one fix if
it's low-hanging fruit or else add a FAQ item.

¹ it used to be part of RFC1725 of 1994, but was removed in RFC1939 in
May 1996.

Cheers,
Matthias
