No, all you need to do is admit that the mailing list server sent the

Besides the semantic wrongness of this approach and the confusion
between envelope and header addresses, it has the severe practical
problem that the address of the actual author of the message no long
appears in a header, so there's no way to reply to her.
one obvious partial fix is a "originally-from:" header - I seem to have
seen comments that Google Groups is adding an "x-originally-from" header
to list traffic.
a longer-term fix would seem to be to get serious about an effort to
develop SMTP2, or some such refactoring that incorporates
authentication, integrity, and mailing list functions into the message
format and SMTP state machine definition in a standard way (any ideas
who might fund some focused work in that regard, the way ARPA and NSF
used to fund protocol work?)
