Actually we have user that automatic redirect messages to their personal = accounts. And this behaviour is not 100% approved by the university.

I leave this = job to my final destination. It's not easy to get the final destination = since we have some different end destination servers and a separate = mailman server. I can't really understand your example: in this situation everything = will be "disclaimed"; and I just want to modify messages to people that = receive their corporate emails in their personal account.
