Section 7 says:
The list of SMTP extensions provided on page 10 of RFC 4409 unfortunately is incomplete. As far as I can see, the following RFCs with SMTP extensions predate the publication of RFC 4409: o RFC 2645 -- ATRN o RFC 2852 -- DELIVERBY o RFC 3865 (+ RFC 4095) -- NO-SOLICITING o RFC 4141 -- CONPERM, CONNEG [ o RFC 4405 ]
Notes:
Quickly browsing these RFCs, I found that only RFC 4405 has
followed the specification in Section 7 of RFC 2476 (literally
carried over to RFC 4409):
Future SMTP extensions SHOULD explicitly specify if they are valid on
the Submission port.
and contains a definitive statement to this end.
RFC 4405 therefore arguably might be excluded from the list.
It would have been useful to have a complete list, with the
proper applicability keywords for the above SMTP extensions.
