Tacking my domain name on somebody else's email address
puts it in the wrong place. Better to leave it alone.
The Postfix author seem to agree. Postfix has
changed so that the default is to rewrites only the mail sent
by local users. For the rationale and further detail see:
You are correct, there is no right answer. I am able to
configure Postfis so that Mailman mail is not rewritten,
but it would be more straightforward if Mailman
had another knob to frob. I will see what happens
and if there are too many problems then I'll
change the rewriting rules.
(I'd tend to favor bouncing such incoming email. But
given the application that's not an option.)
Thank you for the input. It has been helpful.

P.S. FYI. I'm pretty confidant it's Microsoft
software that's causing this headache, although
I couldn't say whether it's Outlook or Exchange.
