I'm sure I get sent a lot of spam (though I don't know for sure -- see
below). But I don't think much of it comes from Usenet harvesters any

Don't do that. Get your mailserver to /reject/ spam during SMTP with a
5xx code. Bouncing spam is really bad because it implicitly assumes
that the envelope sender address is good. Spam rarely has a valid
envelope sender. If you're lucky, the envelope sender is simply
invalid, and you'll end up with a double-bounce when your mailserver
finds out. If you're unlucky, the envelope sender is a /valid/ address
from the spammer's list and some innocent victim will end up receiving
your bounce (this is called `backscatter').
