Hi, PHB. Looking good.
I wish I knew why all the folk on slashdot seem to be so upset
with PHB, starts to make me paranoid.
Did you mean to say "the sender of the email"? (This would be in the
header of the sender's email.) Or did you mean to say "the domain
owner"? I think it should be part of the domain's published policy,
actually I think that's what you meant too.
Domain owner
Perhaps there are other Headers worth checking (*Resent*?).
What is the defined, actual, use of resent?
Actually, perhaps blanket allowing the check to be against
Sender: instead of From: isn't a good idea.
My mail client (Mozilla/Tbird) doesn't display Sender:,
unless I set it to display all headers.
Well there probably should be an escape valve for mailing lists,
forwarders etc. But this can probably be narrowed beyond what
I proposed.
