Here's a slightly more advanced version of the above, using Scheck_mail
from sendmail 8.8.x... It'll block domains, or specific users if
specified...:
---
F{JunkMail} /etc/mail/junkmail
Scheck_mail
R<$={JunkMail}> $#error $@ 5.7.1 $: "You are banned."
R$* $: $>3 $1
R$* < @ $={JunkMail} . > $* $#error $@ 5.7.1 $: "You are banned."

Then the junkmail file looks like this:
----
pobox.com
interramp.com
plevin@monmouth.com
pete@scanplus.com
r9ch@aol.com
----
You can look up the above via:
