Since Jason develops TMDA, and since TMDA (which I just installed under
qmail) successfully intercepts email messages and either holds them
for later deliver, or bounces them, or deletes them, I'm pretty sure
that (a) qmail actually allows such things, and (b) Jason knows most
of how to do it. :-)

I was going to reply to him (before I recognized his name) to say he
might look at the TMDA source for inspiration, but obviously that would
be the least useful help I could give. :-)

(Jason, I've had TMDA installed for about ten hours, and already my
spam level has dropped to zero.  Thank you!)
