Well, don't do that; reject permanently, and they should never try
again. You can issue a message like "congratulations! your message
scored X in our spam filters", too. It won't make much difference to
spammers, but any real users' messages which hit your spam filters will
get bounced back to them - by *their* mail server - so at least they
know the message didn't get through, and why.

Cheers,

John.
