dovecot - Jan 2007 - repeat downloads of message headers in 1.0rc19

I upgraded one server to 1.0rc19 (from rc15) over the weekend, and have 
since received several reports of dovecot erroneously retrieving older 
messages as new mail.  I've seen this myself intermittently on KMail, and 
users have reported it on Thunderbird, Squirrelmail, and Outlook.

I see some things in the archives that suggest that this was a problem in 
older 1.0 release candidates, but hadn't experienced the problem myself 
until just now.

Has anyone else seen this problem?

Regards,

  - Brian

I reported this against rc7 and rc8, and still see it occasionally. 
(I'm running the rc8 that comes with Fedora 5).

It is always associated with this message in dovecot.log:

dovecot: Oct 23 19:26:17 Error: POP3(user at domain.tld): mbox sync: UID
inserted in the middle of mailbox /var/mail/vhosts/domain.tld/user (12 >
4, seq=2, idx_msgs=5)

Once this happens, dovecot will refuse to clear out the
mbox file when the user retrieves email via POP.  Each
time the user logs in to retrieve mail s/he gets everything
in the mbox, which continues to grow.  The only fix I've
been able to find is to manually delete the mbox file.

I'm using postfix as the MTA.

Is something besides Dovecot modifying the mbox?

Do you mean the above error keeps coming back again and again? If so,
please put the mbox in such state through
http://dovecot.org/tools/mbox-anonymize.pl and send the anonymized mbox,
dovecot.index and dovecot.index.log files to me.

If the error doesn't appear again but the user still gets all the mails
again, there's something else weird going on..

Or have you tried this with rc20 or later? I think some bugs in rc19
could have also caused this..

Have you tried if this is still happening with rc22?
