I have these three in my sendmail.cf:

# DNS based IP address spam list sbl.spamhaus.org
R$*                     $: $&{client_addr}
R::ffff:$-.$-.$-.$-     $: <?> $(host $4.$3.$2.$1.sbl.spamhaus.org. $: OK $)
R$-.$-.$-.$-            $: <?> $(host $4.$3.$2.$1.sbl.spamhaus.org. $: OK $)
R<?>OK                  $: OKSOFAR
R<?>$+                  $#error $@ 5.7.1 $: "550 Email rejected. See

(these start around line 999 in case you want to know where to start 
looking and/or adding)


Today I've blocked 86 spam emails so far. 9 were blocked by spamhaus, 3 
were blocked by ordb, and 63 were blocked by njabl.  njabl does the 
heavy lifting for me!
