I would've thought that this would have been integrated, esp. since the
mhonarc mailing list is majordomo:
When majordomo does a resend, it substitutes some value in the From:
field. So, an mhonarc archive driven by a majordomo list would have all
of the from addresses be whatever that value is. The way that I know of
to fix that is to consider the Reply-To field to be the person that the
message is really from.
What is a 'resend' in majordomo? I have not used majordomo or
manage the mhonarc list. I have never seen the From: field
not be what is expected from mail I've seen from the mhonarc, or
other, lists.
