FWIW I just tried the sdbox mailbox format for a singe user (not the whole installation) by overriding the mail-userattr via ldap and the problem persists, so I don’t think it’s an issue with maildir per se, but rather a pop3 / replication issue or a misconfiguration on my side.

Hi,
When I enable (and it only happens when it is actually running) replication over TCP my users get duplicate mails via pop3. Here’s what happens:
- User gets mail
- Mail appears in (Maildir) new/ folder on both replicas
- user retrieves mail (retr), calls dele. Mail still exists in new/ folder on both replicas.
- user runs retr (and gets the duplicate) and dele a second time, the mail is actually removed. If I disable replication this behaviour goes away. I use dovecot from debian stable resources. Any help would _really_ be appreciated. I found one german thread that dealt with the same problem, but no solution for it (http://www.dovecot-buch.de/mailingliste/pop3-fehler-bei-delete-und-dsync-rep...)
