<draft-klensin-rfc2821bis-08.txt> as a Draft Standard
In section 4.1.3 <dcontent> is undefined, fix proposed
in <http://article.gmane.org/gmane.ietf.smtp/6622>
<Standardized-tag> got no valid syntax, proposed fixes
in the same article.
For an <IPv6-addr> importing or adapting <IPv6address>
from STD 66 would be clearer: The STD 66 syntax works
as is, without any additional restrictions in comments.
In section 4.2 <text> is undefined, it is unrelated to
the <text> in 2822upd. Proposed fix, add a definition:
text = 1*(%d32-126)
In section 4.2.2 (reply codes by function group) 251 and
551 should form one group. STD 10 has a simple working
philosophy about 251+551, unfortunately broken by STD 3.
In section 4.1.2 <Keyword> and <Argument> are apparently
unused and can be removed. For the collected syntax see
<http://hmdmhdfmhdjmzdtjmzdtzktdkztdjz.googlepages.com/2821bis.ABNF.1>
The ehlo-greet = 1*(%d0-9 / %d11-12 / %d14-127) allows
NUL and obs-NO-WS-CTL, maybe this is a fair warning for
SMTP clients that servers can be peculiar.
On the SMTP list Mark E. Mallet yesterday (too late for
2821bis-08) proposed a few clarifications. About four of
his points could be errata if they'd make it in 2821bis.
