Hmmm... or  The spamcop DNSBL is one of the better ones
I've tried.  Currently I'm getting about 20--30 rejected connections a
day from that, and spamassassin mops up anything that does scrape
through. Here's my experience of the OP's spam message:

/var/log/maillog.3.gz:Aug  5 20:47:24 happy-idiot-talk sm-mta[18121]: rules=
et=3Dcheck_relay,, arg2=3D24.233.3=
7.31, [], reject=3D55=
0 5.7.1 Mail from rejected using DNSBL. See http:/=

There's something deeply satisfying about bouncing the spam at the
check_relay (HELO) stage -- although I am somewhat tempted to delay
the tests until the check_rcpt (RCPT TO) phase and change the bounce
message to claim that they're trying to send to a non-existant
