Actually, thinking about it, the listserv adds a footer at the bottom of
messages, so DKIM signatures would need to be stripped anyway or they'll
mismatch regardless of fiddling with From, so maybe that's a moot
point.  So it would probably not improve things to change the From
behavior, but I doubt it would hurt.
