Tiny bit of background, then a question...
In January, we upgraded our AS measures on our mail hosting server (CommuniGate Pro on FreeBSD) to include SpamAssassin 3.0.3, and we built a SpamCop account at that time so we could use SA's reporting mechanism to submit stuff to SC in a moderately automated way (a human still has to start the reporting run...).
Having done this a couple of times, we now find ourselves listed in the SCBL, and I am pretty sure it's a result of us reporting spam mail destined for one (or more) of our customer domains.</BACKGROUND>
<QUESTION>I have begun to add mailhost entries for our server to the mailhost system, but for the two domains I have used for testing (the ones on our server for which I have a physical account) I am getting only a single mailhost record with the two external IP's for this machine listed. Do I need to register all the other domains (30-odd), or will the mailhost system work them all out from the IP addresses (both of which are now in there)?
