[EAI] draft-leiba-5322upd-from-group discussion

[Barry Leiba <[e-mail]>]

I think the subject document will do; please review it:
http://datatracker.ietf.org/doc/draft-leiba-5322upd-from-group

The "replacement for 3.6.2" section should be solid except for one
issue, noted: one sentence needs to change, for our purposes, and we
need to decide how to make the change.

   If the from field contains more than one address in the address-list,
   then the sender field, containing the field name "Sender" and a
   single mailbox specification, MUST appear in the message.

I don't believe that we plan to use the "Sender" field in the cases
where we'll use group syntax in "From", so that MUST can't stay.  The
simple change would be to make it SHOULD and have done with it, but
I'm not entirely happy with that.  The alternative is to leave the
MUST, but add "unless...", and then we have to craft the "unless"
text.

Please also review the Security Considerations, and make sure I got that right.
