Would you really "sync" or just "backup"?
To help decide, are you changing messages on both servers or is the second one just a backup-server?

In case of backup you could use this command:
doveadm backup -u user at ssh doveadm dsync-server -u user at

Could this help you?


Mit freundlichen Grüßen / Distinti saluti / Kind regards
