As I said in a private email to Ken, and just now in another
relating to Mutt, this behavior is intentional as some email
systems, notably Yahoo! and hotmail, implemented blocks on
incoming messages if they enter their systems from a system not
under control of the From/Sender's domain (e.g. it would be
bounced if the mail was From: user at hotmail.com, and comes from a
celestial.com server).  This resulted in 40+ automatic
unsubscribes due to bounces.  This occurred in mid-August.

I had to update the Mailman Mailing List Manager to work around
this, then manually resubscribe the addresses.

The new behavior is that messages to addresses in the domains
that do this kind of blocking now have the From: address
rewritten with From: ...<filepro-list at lists.celestial.com> and
the Reply-To to the original sender.  Messages to people at sites
that don't do this type of blocking shouldn't be changed.
