Can you detail this A <-> B replication setup more? I've been trying to 
figure out how to make use of the new 2.3.7 replication features outside 
of a murder. The thing I can't wrap my head around is the following 

1) Server A dies
2) Users are sent to Server B via DNS redirects
3) Server A is restored
4) Mailboxes on Server B are now more 'current' than mailboxes on Server A

In other words, the failover is easy(ish) but the failback has me 
scratching my head. I Think two way replication solves that.
