I'm using milter-ahead and Spamhaus on my backup mailserver. Milter-ahead looks to the primary mailserver to see if the user exist before excepting mail for the domain.. unless the primary mailserver is unreachable, at which point it accepts anything. (rare ocassions). Milter-ahead makes use of the mailtable and relay domains to know if it should be dealing with email for our domains.
So many spammers are finding the backup mailservers and sending directly to those, I found this absolutely a must do as backscatter was getting terrible.
I keep all my e-mail users on MySQL, and use database replication for that. Works like a charm, with very low traffic between the servers.
