I just upgraded to Mailman 2.1, and apparently a change has been made in how
the From: header is contructed. I'd like to change it back.
The specific issue is that mail for each list appears to the client as from
<listname>-bounces at domain.com instead of as being from the actual sender,
which was the behavior previously.
It's a minor issue, but it's irritating a lot of my subscribers, so I'd like
to resolve it.
