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.
