Yeah, loops are my biggest fear. >The easiest way to solve this would probably be not to have your IMail >server listed in the MX record. Yep. Of course that won't help in the case of local mail. I was hoping to find a solution for that as well, as it would be nice to have *EVERY* message passing through our IMail system pass through Postini first. Thanks for the advice.
