RFC 2822 3.4 punts the components of dot-atom to STD 3/13/14.
STD 13 is RFC 1035, which, in 2.3.1, suggests (but does not impose) a
standard for domain name literals which appears to expand to a pattern
which does not in fact permit a trailing dot.
In fact, Mutt (1.2.5) permits the trailing dot, and delivers the mail,
and all the intervening MTAs (I only tested local mail on my machine,
running Postfix) let the message through -- it came through apparently
having been rewritten by Postfix to lose the trailing dot; there was an
Tony: what authority were you depending on for your assertion, and in
which context do you make it?
