Sorry, I have just returned from holiday to find all this fuss.

I disagree totally with Frank on this one.

draft-ietf-usefor-usefor-12.txt currently contains:

   message-id      =  "Message-ID:" SP *WSP msg-id *WSP CRLF

   msg-id          =  "<" msg-id-core ">"
                      ; maximum length is 250 octets

   msg-id-core     =  id-left "@" id-right

which is effectively the same as what Tony proposed, bar the usual Netnews
compulsory SP after the ':'.

We currently have the situation whereby <message-id> is differently
defined in the two documents, so I cannot see why Frank should object to
having <msg-id-core> defined differently in the two places (in fact, in
USEFOR it is <id-left> and <id-right) which are defined differently).

My own personal preference, now that 2822-bis has tidied the syntax of
<msg-id> to the extent that only one very minor difference exists from
what USEFOR should be like, would be to pull back the USEFOR draft and
rebase it on 2822-bis (which would remove from it some exceedingly ugly
syntax which, with the new 2822-bis, is now totally unnecessary). But that
is a matter for the USEFOR WG to decide.

So this is a belated +1 for Tony's change.
