ah.  Wouldn't From come at the same time as return-path?  I've received
plenty of mail (spam) without a return-path, so it'd be nice to have
SOME way to match those messages.

And I'd rather not use maildrop - I want the spammers to get a rejection
from the smtp connection, not some bounced message that might hit an
innocent forged-addressee.
