I appreciate the suggestion, but VERP (as I understand it) changes the
return-path.  I do not get to see any headers, including return-path, other
than the ones I mentioned (To, From, CC, BCC, Subject and the Body
itself).  So, I do not believe VERP will help.

I need a way to put some clue about the recipient into the footer, when
personalization is enabled.  I've seen some past solutions where admins
were successful in adding some type of hash or encoded version of the
recipient's email address into the footer, but the steps to get that done
were not shared.  Open to other ideas.
