AFAIK this is an Outlook-specific bug, and not a Mailman issue.  What
is happening is that Outlook is ignoring the "From" header and using
either the "Sender" header or the envelope sender as the return
address.  This is in violation of the Internet standards for mail
clients.

I realize that it's hard to get users to change their mail clients,
but that is the right solution to this problem.

Mailman does not "send out mail as itself" in the default
configuration; it simply forwards the mail and leaves the author's
address in place.  However, because it is sending mail to many
addresses which may or may not be valid, it lists itself as the
"Sender" so that delivery problems will be referred to Mailman, and
not to the author.

It is not possible to configure Mailman to use a different Sender.
This is to protect your list from being spammed by returns of
undeliverable mail.
