If I had to build this as a central system I wouldn't use Linux for the
storage systems, I'd probably look into Hitachi or similar disksystems
with a SPARC running Solaris (or several of them running in tandem)
and some Veritas volume management.
Another solution would be a bunch of Network Appliance boxen, with
their own microkernel and NFS.
These systems would be the backbone of the system.
As frontends I'd probably use some kind of x86's or Alphas running
Debian, probably with qmail or postfix using their local disks for
temporary spool areas.
Between these I would run a Gigabit Ethernet, using one of the fast
giga switches (No names mentioned, no names forgotten ;)
For distributing the load between the mailservers I would look into
equipment with the same features as Cisco's Portdirector, but
probably another brand, since I don't think the Cisco can perform
adequately.
All this would be a costly solution, but I think it will be able
to scale properly.
Another solution, which has already been proposed is a geographical
split of the machines.
