Hi, the 2821bis and 2822upd drafts are "almost" ready, and clearly
better than the older RFCs. Similarly the email-arch draft is
"almost" ready. A few open points are however critical, maybe
controversial, and getting them wrong would be dangerous.
Mail and SMTP is as important as HTTP, and the 2616bis folks got
a proper WG to sort our their nits. Mail and SMTP deserve the
same care.
* 2822upd: The NO-WS-CTL issues are critical, they do not only
affect 2821bis, and checking all details is a difficult task.
* Email-arch: Recent drafts such as MINGER and TBR need a term
"border" or "boundary" MTA, and email-arch should explain what
that is as common reference.
* "Bounce address": IMO this is no *concept*, it is only an
obvious *function* of the "envelope sender" concept formerly
(STD 10) known as "reverse path". It needs some fine tuning
of 2821bis (mostly done) and email-arch to prsent this as
unique idea, essential for SMTP, like a Message-ID is essential
for NNTP.
* IPv6: We should at least discuss Doug's proposal to get rid
of the address fallback for IPv6. Maybe the 2821 "bug" of not
mentioning AAAA can be turned into a 2821bis "feature".
