Agreed.

I think that there are two problems that we haven't solved relating to
address books.

1) a standard header which says, "The stuff in the From: address is useless,
   please don't remember". It might also indicate the whole "this mailbox
   is not monitored" business.

2) a standard header which says, "If you want to remember who this was from,
   you should record XYZ"

Of course, From: was supposed to be (2), and we also have Sender:,
and we have the SMTP From which was supposed to be for errors.

(2) might really be a no-op with no legitimate use, and/or it might have
    some significant downside.
