I would have one machine as mailbox server (postfix + pop) and a second box as MX host for in/out gateway and anti-abuse configs. See IMGate in my sig . Several 100 ISP's and other orgs run IMGate with great success. On the mailbox server, I assume you are disk i/o limited (mailbox read/write, mailqueue read/write, logging), so caching SCSI and two or more disks would speed up the disk channel. But we need more info about the specs of your box, and what software it's running.
