We are testing a number of email configurations for a 10,000+ user-base. Was hoping to get some thoughts on below:
- Postfix - Cyrus-SASL - Mysql Auth We will likely start with 3 frontend servers and 3 backend servers. Replicate MySQL across all servers auth, maildrop routing. We were thinking of doing some sort of rysync of the imap mailstore across the backend servers. Then Heartbeat on the backend servers with IP takeover to handle failover. The hope is that if a server goes down the mailstore will be sync'ed up on the server that takes over. Thought? This is obviously just a sketch... but I haven't seen a this done before as far as the failover solution with rsync and thought it might work pretty well.
