Hi,
I've recently seen the following issue. A user logs in with pop3, and sees zero e-mails. The maildir contains emails both in cur and new. The mail delivery is done with qmail, and this user have had no logins before, so it has only the inbox, trash and sent (while dovecot is configured to create drafts and spam folders too). Because of this, the user doesn't have any dovecot indexes either.
So, he logs in, and sees nothing. The strange thing is Dovecot doesn't create any of the above directories nor indexes. After moving the mailbox to another server, the user can log in, the additional folders get created and also the indexes appear. pop3 shows the correct amount of emails. Moving the mailbox back to the original server shows the same issue: no emails at all. Restarting dovecot on the original server resolves the issue. This is a pretty loaded machine, so I couldn't trace the processes. I know that this isn't too much, but that's what I have.
The only thing I could identify in the error log is: Feb 17 12:45:58 pop3(varszr@asdfg): Warning: Created dotlock file's timestamp is different than current time (1297943148 vs 1297943086): /home/varszr@asdfg/Maildir/subscriptions
Which may happened due to a restart and maybe a clock setting. But that was yesterday.
Any ideas?
