[Dovecot] Need help with Replication

Wed Sep 11 15:34:48 EEST 2013

Hi!

I set up two mail servers with Postfix and Dovecot and I would like to sync
all mails between the servers. So I set up replication.

Now I'm still getting the following errors:

=======Server 1=======
Sep 11 13:43:52 mx0 dovecot: master: Dovecot v2.1.7 starting up (core dumps
disabled)
Sep 11 13:43:52 mx0 dovecot: auth-worker(4245): mysql(127.0.0.1): Connected
to database mailserver
Sep 11 13:43:52 mx0 dovecot: dsync-local(user1 at domain.com): Error:
stat(/var/mail/vhosts/domain.com/user1/.dovecot.sieve/tmp) failed: Not a
directory
Sep 11 13:43:52 mx0 dovecot: dsync-local(user1 at domain.com): Error: Failed
to sync mailbox dovecot.sieve: Internal error occurred. Refer to server log
for more information. [2013-09-11 13:43:52]
====================

=======Server 2=======

Sep 11 13:45:34 mx1 dovecot: dsync-local(user1 at domain.com): Error: Worker
server's mailbox iteration failed
====================

Currently Server 1 holds all mails. Server 2 has no mails.

Dovecot Version: 2.1.7 on both servers.
