Another option, if you're using a recent version of sendmail,
is to put something like the following line in /etc/mail/access:
david@iant.com 550 Invalid username
Then remake access.db:
makemap hash /etc/mail/access.db </etc/mail/access
The benefit here is that the message itself is not delivered to your
mail system. Instead it is rejected during the initial "MAIL FROM:"
"RCPT TO:" phase of the SMTP transfer. It also has the benefit of
returning a bounce message to the sender, on the off chance they'll
actually process it. It does -not- send a message to your postmaster
account, even if the return address on the spam is bogus.
