Thanks Brad. Now that you mention it, I recall seeing this on the list
several times before.

It isn't AFAICT. I was going to add it, but I am looking for a specific
RFC reference. I have looked at several RFCs and I don't see anything
that talks about rewriting domains in headers. All I found was RFC
1123 (STD 3), sec 5.2.2 which requires that canonical names, not
aliases, be used in MAIL and RCPT commands. Can you tell me where to
look?
