Re: [Dovecot] messages downloading repeatedly to mozilla/seamonkey pop3 client

[Ben Julian]

Timo and Mark,
  It appears that my problem was due to our configuration of the
user's several home directories - we had different usernames created
for this individual, but two of the home directory definitions in
/etc/passwd were unintentionally pointing to the same place, causing
the dovecot index files to overwrite each other.  We never caught it
before using pop3d, because they don't keep index A silly mistake.
Sorry to bother you and the mailing list with this - clearly user
error. :)
Thanks for all your help!
Ben

Timo,
  Wow, thanks for checking back on this after all that time. I am
actually still having problems, and just working around them by using
a script to manually wipe out the inbox and index files for the user
with the problem.  I tried your suggestion of explicitly setting the
mailbox location.  It didn't seem to stop the problem, but it is hard
to reproduce on demand.  By sending the user a lot of forwarded mail,
I was able to reproduce the issue once.  I left it defined and tried
Mark Sapiro's suggestion, adding " pop3_lock_session = yes", and so
far, so good.  I won't really know until a few days of use have
passed.  I'll be sure to let the list know how it turns out.  Thanks
for the follow up, guys, totally unexpected.

This looks a lot like the issue I reported last month at

which see for configuration details.

At that time, I thought the problem was due to a conflict between
Postfix adding a message to the mbox while dovecot was expunging
messages. I have since seen the problem one more time apparently
precipitated by two remote boxes accessing the same mailbox via
separate dovecot processes simultaneously.

I have since added

 pop3_lock_session = yes

to the dovecot configuration, and I have seen no further problems,
but it's only been 2 weeks since I made the above change so it's
too soon to know for sure.

Do you still have this problem? You could try setting mail_location
explicitly to see if it changes anything
(http://wiki.dovecot.org/MailLocation).

Timo,
  The user can't access the mailbox directly under normal use
circumstances.  He doesn't have a smb share setup to allow him access
to the mbox file.  As far as I know, the only program besides dovecot
doing editing of the mail is spamassassin, but that happens before the
mail is written to the mbox.  Perhaps I am misunderstanding your
question?

This is the main problem, these shouldn't happen. Can the user access
the mailboxes directly?

Asheesh,
  Sorry about the long delay.  I tried upgrading to version 1.0.12,
which I understood to be the newest release for CentOS 5.I am
still experiencing the problem.   What should I try next?
Thanks,
Ben

I've subscribed for a month or so now and searched the archives, but
if I missed a solution to this in there, I apologize.


That sounds like a drag.  Let's see if we can help you.

Can you paste the results of dovecot -n into a message?  That way we can 
see your whole configuration.  What version of Dovecot are you using, and 
where did you get it from?


(I'm expecting you to tell me you're running some really old version, and 
I further expect that if you upgrade your woes will go away; but let's 
see!)
