So is there a way around this? What if I made the Imgate as their SMTP server? Any suggestions? Thanks.

It sounds like you are saying this: You have two domains, example.com and fubar.net, both hosted on IMail. When the world sends to either of these, all rules are applied. When example.com sends mail to fubar.net, it does not go through header checks. The reason why this is so is simple. IMail is internally aware of all domains it hosts locally, and it simply does internal delivery via the queue for these domains. You can send yourself an email between locally hosted domains and look at the headers to prove this. Another thing about header checks is that they do not always work as expected. Same with body checks. These are very literal checks. Small differences are important. --Eric
