This is slightly tangential to your question, but whilst trying to block
mail from open relays, just be careful that you are not turning *yourself*
into an open relay with that rule. It depends on what rules you have
before it, but what happens if some random third party (i.e. spammer)
does:

MAIL FROM: <thisisfaked@???>
RCPT TO: <spamvictim@???>

?
