I have my main mail server to all the mail related work, and mail passes through spamc (on the main mail server) which calls spamd (located on a spam machine, which could easily be many machines in a round robin list), to keep load down on the main server, specially when users are running the learning tools (which we allow each user individual spam bayes db's). Plus, you can work in a little failover stuff with virtual IP's and such for redundancy.
