I'm having similar problems (and have, off and on, for a long time,
including with other mail servers).

One of my users is seeing duplicate mails occasionally too. Client is Sylpheed with POP3. It is quite seldom, maybe twice a month, using POP3 several hours a day. We've been seeing this for some time now, including up to rc13.
Is the client configured to keep the mails in the server or delete
them?
In my case, yes. I mean both. ;-)
What do you see in logs? Does the client disconnect normally, or is there a timeout, crash or something?
Nothing exciting in the logs, everything looks normal.
If the client is configured to delete the mails, I think the only possible reason is that the connection dies before the mails have been deleted. So when that happens, it would be useful to know what exactly the log says was the reason. Possible reasons are:
- Logged out: A normal logout with QUIT command. Should have worked correctly.
- Disconnected for inactivity: This has sometimes been a bug in Dovecot, but I'm not aware of any such bugs currently. It could also just be a network problem.
I recently got a set of duplicate emails (including this one). I did
have some connectivity problems late last night, and this I saw in
the log file:
Dec 1 10:42:04 stove dovecot: [ID 107833 mail.info] IMAP(kamath):
Disconnected for inactivity
