Thanks. I tried it, but it appeared to strip the header from emails that the "/From: " line didn't match. I'm going to try going the route of a check_sender_access table entry that uses a 'FILTER transport:' action to send matched mail through a custom transport. That transport/service entry in master.cf will then apply a single header check to strip out the header. I've been fighting with the appropriate settings for the entry and haven't made much progress, so I will probably drop into the Postfix mailing list soon and ask for some help there pointing out my obvious mistake. Thanks for your feedback.
