I have to take two copy of incoming mails on different servers(local & remote). I am using plain server without any panel on it and using sendmail, pop3 server Dovecot.
Is there a way(any configurations) to take a remote backup for all incoming mails? except configuring forwarder to each mail ID !!!!
Oh yes, quite a few:
Do it on delivery (by configuring your MTA to deliver to two places at once)
Use a tool like imapsync to replicate the mailboxes using IMAP periodically
Use filesystem-level replication (e.g. rsync/unison, ZFS mirroring)
Use block-level replication (e.g. drbd, Netapp snap-mirror)
Which you use will depend partly on what the replica is being used for, e.g. just for archive/audit; how quickly it has to be in sync; what happens when the remote replica is unreachable; and whether you want to be able to failover to the replica for 'live' use, and fail back again.
