It is difficult to understand what the issue with any message would be
that would allow Gmail to correctly display the Subject: and Sender:
but Hotmail not.

Possibly you have a hard return at the end of your address in
reply_to_address. I don't know offhand what this would produce in the
generated Reply-To: header, but if it were some kind of encoded
return, Hotmail might see it as the end of the headers and Gmail not.

I would like to see the raw message as sent from Mailman. I don't think
you can get this in Hotmail, but in Gmail, in the message view, near
the top and to the right of the date and the swooping 'reply' arrow
there is a down arrow for 'more'. Pull that down and click 'show
original'. Then copy and paste all the headers - you can mung things
for privacy if you wish, but try not to obscure anything that isn't
simple text, and not particularly if there seem to be any blank lines.
