Any ideas of what program can be installed reasonably painlessly and cheaply (preferably free)I'm not sure what you mean by "Spam Attacker" but with some Sendmail tinkering, you can use any of the various DNS blocking lists such as ORDB, SPEWS, Monkeys open proxies list, SpamCop BL, etc. Jeff Lasman can certainly help you with it. There are also some old posts on using Spam Assassin <http://www.spamassassin.org/> which I believe most use to tag and filter the spam. (I think there's a .pkg somewhere for it.) Personally,

It may be a little much for the good Rev. to do on his own, but I imagine it's best to let him take a look and judge that for himself.
While DNSBLs are, as Dan says, the most processor-efficient way to block spam, one very much needs to go in with their eyes open. We're a publishing company specializing in biology and neuroscience and found ourselves blocking one of our own authors from UConn. Why? Well, he did fieldwork in Costa Rica, and the Costa Rica state telco apparently has a checkered history on spam. Many lists block its entire netblock, which in effect locks down all of Costa Rica.
We continue to use DNSBLs, and I continue to agree with Dan that rejecting at the MTA level is the best way to go, but beware of the law of unintended consequences.
