virtually guaranteeing that your auto-responder never gets fed a spam
message, or (2) disallowing auto-responders.
PS: If you *must* use an auto-responder, please make sure it behaves
at least as nicely as Sendmail's "vacation" program, which is one of the
better-written auto-responders. I've banned a few people from this
list for using broken auto-responders.
