FWIW, building from source on RHEL 5 on a Xen DomU with 6 cores and 2GB memory, currently delivering around 150msgs/sec via postal to ~350k accounts (via LDAP). Storage is all "Xen phy:" storage to a EMC DMX (metadata) and IBM 4700 (SATA, mail storage), 6 LUNs of each. I'm pretty happy with those numbers. Raw hardware would of course be better, but I find the overhead of Xen to be worthwhile.
