It would be interesting to see what a session from the system log looked like. You'd have to set the SMTP sending log level to low-level or all info first, then catch one of the problem sessions. I can't see how preserving the To and Cc fields should have any impact on "relay" settings as long as your server and theirs are behaving properly.

It sounds like someone has a server that ignores the SMTP protocol and tries to deliver the message based on the To and Cc headers. Very bad idea....
