I don't have a strong opinion on whether or not that's the best way to
handle this, but I'd like to point out that RFC 5321 has quite a bit
to say about the format of such lines.  It also seems to imply that
these are added by "gateway, relay, and forwarding systems".  I would
guess that Mailman qualifies as a forwarding system in which case it
whould probably try to conform to the RFC 5321 syntax.
