Question: Is it time to formally deprecate 821 and, in

HELO by SMTP clients? We would still need to require that SMTP
servers accept it, but we would tell full-capability clients
(including the client side of relays and gateways) that HELO is
obsolete. One corollary of this is that we'd be telling
low-capability clients, particularly those that are part of MUA
systems, that they should be talking to Submit ports, not SMTP
ones.
I'm ok with this. Simply because EHLO's requirements for a FQDN is
clearer than HELO.
