Hi,

I have a single Dovecot (2.3.4.1) IMAP/LMTP server on HQ "A" and I would like to create a backup server distributed to HQ "B", two HQ are connected through an IPsec tunnel.

User mailboxes (type mbox) are on NFS storage.

I don't need HA, it could even be an active / passive configuration with a floating IP, but I don't know how to keep in sync the two remote NFS filesystems.

I don't know if Dovecot replication is suitable for me.

Thanks
