Gary... With all due respect. Assuming that the mail coming from your servers is not affected by something bad is a mistake. Not to mention, spam that uses your domain as email addresses in the to / from to get around just the kind of scenario is also makes your strategy a mistake.

What harm besides having your server do some work would be caused by having all the mail scanned?

I don't have a need for scanning the outbound e-mail from this server but I do need to have the inbound mail scanned.  So I figured I would add the domain to scan.messages.rules.

These messages are not being scanned and getting passed through due to the rule above.  Obviously, I didn't think this through correctly and I need a better solution.
