I'd like to add my $.02 as well.  I think this would be a great feature,
and since admins could choose to use it or not I think it might be
helpful to have it on by default.  But since many list readers (and
possibly owners) might not understand exactly how it works, here's my
thought.

Have it turned on by default, but when Mailman sends out the message it
adds a header to the mail; as Nathan later suggested, having it
automatically set the "Reply-To" to include the sender so they get
copies of replies would be good - better would be for Mailman to do it
automagically, but that would require a bit more work to keep track of
who submitted what mail, etc (things which MM isn't currently stateful
enough to track, though I don't know what other 2.2 plans are in the
works).  The other would be a "header" in the body of the message,
perhaps something like:

 [This sender is not subscribed to the list, but their email is being
sent through because it is cryptographically signed - replies to the
email should be CC'd to the original sender]

Having it on by default might be seen as a "back door" to some, but off
by default means people would have to see the benefits of turning it on
before they'd do so.  Since signed mails are likely to only be done by
people who know what they're doing, and I'll guess are also less likely
to be the type to post nonsense to mailing lists only to add to clutter,
I'd think it would be safe to leave on.  And by having the header there,
it would probably alleviate those readers/admins that would wonder, "How
the hell did they post on here when they're not subscribed..."
