One way, is to setup a very reliable disk server system and export the mail spool as NFS. This box will do nothing but dish up files. Then, plug in a couple of mail servers with dedicated 100Mbit or 1Gbit ports to that NFS box. The mail servers then mount /var/mail from the NFS server. If the NFS server goes down, you're hosed, but because its behind another layer and not directly on the internet, its not as susceptible to attack. There is some kind of BSD fail-over tool too, that brings up a second box on the IP if the first box fails.
