[fetchmail]5.8.14 POP3 keep/flush bug (fix included)

2001-07-18 00:20:43
Hi there,

I just found what I think is a bug in 5.8.14's POP3 flush/keep behaviour.
I fetch my mail using "keep" and "uidl" in my ~/.fetchmailrc, and run a
script once a day that calls 'fetchmail -F' if the number of mails in my
mailbox exceeds a certain amount.

I recently upgraded from 5.8.[789] (don't remember exactly), and suddenly
received all my old mails again whenever the script that should flush my
mailbox was run. Running 'fetchmail -F -v' and checking the logs, I found
out that fetchmail did in fact flush my mailbox properly, but sent a RSET
just before sending QUIT to log off. This caused the POP3 server to undo/
forget about the previous DELEs, resetting my mailbox to its original (ie.
unflushed) state. The ~/.fetchids file did get flushed though, so the
next time fetchmail was run it saw all the old messages as new ones ...

Here's the relevant lines from the log:

Unfortunately I don't know whether this is actually a bug in fetchmail
or in GMX's (<http://www.gmx.net/>) POP server (call me RFC challenged
if you want :-), but the attached diff fixes the bug for me. YMMV.

HAND,
Thomas
