[Dovecot] Duplicate e-mails
Hi,
I've got Postfix/Dovecot config mail server, POP3/mbox, and a few users are complaining about duplicate e-mails.
User connects with Outlook 2003 to Dovecot to download mail. If you check the mail logs for that message ID, only one copy is delivered to his mailbox. Also, verified that the client is set-up to NOT leave a copy of the message on the server.
He downloads a copy of the e-mail once, and then 2 minutes later when his client reconnects to check for mail, he gets another copy of that e-mail. It's not a consistent problem.
I check the dovecot logs, and see his client connecting and disconnecting, and always deleting the same number of e-mails it downloads. Is this a network issue or a config issue?
The only other thing to note is that it's usually an e-mail sent to a group list that he's a member of. And I've set-up the owner-list setting in the aliases file. So I don't think that's the problem.
If anyone can shed some light on this issue, it'd be greatly appreciated.
Thanks, Lisa

So, that means that the mail doesn't get deleted in the server. That happens either if the client doesn't issue DELE command for it, or that the connection closes before client sends QUIT command.

Looks like there's a bug in the reporting. Unless the disconnection line says "Logged out", no messages are actually deleted even though it says they are. I'll fix this.
Are you using SSL?
