Hello, I've two accounts on my mail server, and from my client (Evolution) I've set up two configurations. If I dowload mail one account at a time everything works fine, but if I download both of them at the same time I'm not able to delete downloaded messages, so I download them twice, three times and counting to infinity.

On th client side everything looks good:

LIST +OK 1 messages: 1 485 . UIDL +OK 1 000000704e57eebd . RETR 1 +OK 485 octets Message here...

. DELE 1 +OK Marked to be deleted. QUIT +OK Logging out, messages deleted.

On the server side I've enabled debug logging but nothing relevant comes up, except sometimes an error:

Panic: Message unexpectedly expunged from index Full log: http://pastebin.com/raw.php?i=bBizx9tm

But most of the times there are no errors and simply the message is not deleted. I'm using mbox format in /var/spool/mail/%u. The dovecot user has read-write access to the folder (even because, as I said, if download an account at once everything works fine).

I think it's about locking, I've tried several lock methods but always the same result and I can't see dead locks from lsof, fuser or ls (for dotlocks).

Thanks in advance, venom00
