I'll second that.  Multiple MX records to multiple mailscanners to 
handle normal inbound traffic, plus a mobile IP in a clustered
configuration to handle road warriors works wonders (but that's 
getting more OT).

I don't think you mentioned your MDA, but if you're in the situation
where you're needing multiple multiple servers to handle the mailbox
load, Cyrus Murder is a robust and scalable solution.  Cyrus can also
be easily clustered if you also have to handle failover at the MDA
