Yeah, that'll work great for known IP's.

One problem is that I have a ton of dialup users authenticating via
sendmail and then sending out.. I can't add all their IP's (I have no idea
where they will be coming from), but is there a way in MimeDefang to tell
if the user has authenticated to Sendmail? Not even sure is Sendmail
passes this info, but hey, it's worth a shot.  :)
