[Dovecot] inbox issue

[Tom Pawlowski]

What you're describing has been a symptom of a corrupted index/uidlist
our experience. Now *what's* corrupting it, depends on your setup.

Just to clarify, you're using a single dovecot IMAP/POP3 mail server and
not multiple servers, correct?

And equally important, are you using a NFS backend for the Maildirs?

If so, read these:

http://wiki.dovecot.org/NFS
http://dovecot.org/list/dovecot/2010-May/049031.html

And look into this: http://wiki2.dovecot.org/Director

If not, check the log files, are you getting corrupted index errors for
the users in question? Check their quotas, are they all under?

If they're at quota, then dovecot can't update the index or uidlist for
that user. One solution:

That's what first comes to mind for me.
