Re: Last Call: draft-klensin-rfc2821bis

In an IETF that believes the potential recursion of URNs and
NAPTR records is reasonable, it is really hard for me to get
excited about that one possible extra lookup.   YMMD, of course.

I can't get excited about this either.

      Doug's issue, which sparked off this latest debate, would
      be addressed by codifying "MX 0 .".  This would allow hosts
      to say that do not accept email and any email (MAIL FROM)
      claiming to come from such a domain to be dropped in the
      SMTP session.

OTOH, I think standardizing this convention makes all sorts of sense, but
not, of course, in 2821bis.
