First, please see the FAQ at <http://wiki.list.org/x/RoA9>. Hopefully,
this will explain what MS Outlook is actually displaying as the From: of
the message.

T answer your question, no there is not, at least not as a standard
configuration. This could be done by setting the Sender: to
listname at mymanserver.com instead of listname-bounces at mymanserver.com,
but this would not be desirable as it could result in bounces being
returned to the list instead of to bounce processing.

Are you sure the relay is not looking at the envelope sender rather than
any From: or Sender: header in the message. I would expect that it is,
in which case, the addresses you need to 'whitelist' are the
listname-bounces at mymanserver.com addresses regardless of any From: in
the message.

I suspect the above will work regardless of any list settings.

Try setting anonymous_list back to No, and if you want to "ensure that
discussions will stay on the lists", set reply_goes_to_list to This
list. I suspect that together with whitelisting "*@mymailmanserver.com"
will do what you want.
