I use dd to duplicate hard drives when needed.
dd if=/dev/sdb of=/dev/sdc bs=1M
for example. It's probably in every distribution.
I use rsync to sync up system wide files such as authentication, etc...
and on a per user basis it copies users' .procmailrc and .spamassassin/*
files from a central server.
I use perdition to load balance the mail checking, and load balancing of
SA/AMAVIS/CLAMAV and checking is managed by having certain letters of
the alphabet (for first letter of username) going to certain mail
servers.
I've considered using mysql to make the SA settings available to each
server, but I'd still need rsync to copy passwd/shadow files, .procmail
files, and so on.
Virtualization was presented, but I think for absolute speed, you'll
want to run the OS natively. I use virtualization for lots of things,
but really heavy duty email isn't one.
