Hey. I've setup two mailserver as mirror and I'm using Dovecot for replication as Florian wrote in his Blog: https://blog.schaal-24.de/uncategorized/mails-mit-dovecot-ueber-tcp-syncen/ When I start Code: doveadm sync -A tcp:mx2.server2:23456 everything works fine. All mails are synced. But when a new mail arrives on server1 it isn't synced to server2 automatically. The replicator process is running on both server What can I do else?
