Replication looks to be the solution. Surprisingly I hadn't discovered it on my own. Many thanks to everyone for pointing it out! However, while setting it up, I noticed a really weird thing. When authentication fails on the master-initiated master->slave connection, master will block connections from all clients! That's a seriously weird design choice. Does the same thing happen when the slave goes down? For example, if I reboot the slave, is the master mail server down for everyone while the slave reboots? I have not dared to experiment as when authentication failed and the Cyrus master server stopped letting clients connect, everyone in the office started shouting within seconds.
