Hello Everyone,
I am having a problem with the qmail-pop3 daemon. Not quite sure how
to diagnose the problem. System has been running great for the past
couple of Months. I am running Cent OS 4.3. I did a yum update last
week, and had a bunch of updates. After running these updates, my
POP3 daemon seems to be wigging out. When a user connects via
outlook, the pop3 damon takes a really long time (15 to 20 seconds) to
start to download the messages. This is on a Local LAN. It is
sending Duplicate e-mails to outlook as well. This doesn't happen
with IMAP Users. If they hit send & receive , they get messages. If
they hit it again, they get the same 5 messages, plus any new ones,
and so forth. I have restarted the box, and looked in any log file I
could find with POP3 stuff. I saw nothing unusual. I am pretty sure
that one of the updates that happened last week was mysql. Could that
have something to do with it? Let me know where I can look for
errors, or the cause of this.
Hey Nate. Long time no see. Hope all is well with you, and glad to see
you back.
I had a user last week start getting "duplicates", on a FC4 machine I
run. I have not had the problem on any of the Cent4.3/4.1/3.4 boxes I'm
running. The problem (as far as I can tell, since it's sporadic) was the
old mailfilter script defined in the .qmail file for each user. I
removed this, and the problem seems to have gone away for the moment. Of
special note, I also had upped my spamd/run file to allow more processes
during the same time-frame:
#!/bin/sh
exec /usr/bin/spamd --max-children=6 -L -x -u vpopmail -s stderr 2>&1
I had upped it to 9 children and that seemed to soak my memory - 495M
total, 21 free with children set at 9, 101 free with children set at 6.
Might be worth note to take a peek at this. If the message hangs too
long (can be caused by swaps), qmail-smtpd thinks the message got lost
and resends it again resulting in your duplicates.
Also double check (I know you set it up right, but I have to ask...)
your hostname, me file, defaulthost, and defaultdomain files.
