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.
