I have mentioned specific issues where RFC 2822 causes problems.
But you have not answered the question. We were discussing the <id-right>
in <msg-id>s. Have you heard of any case where this esoteric change of
semantics actually caused a problem?
I have indeed answered exactly that question, in detail.
For example:
Interpreting a msg-id RHS as RFC 2822 id-right means that one
cannot determine whether <foo(_at_)bar(_dot_)com> matches
<foo(_at_)Bar(_dot_)COM>
because RFC 2822 doesn't specify whether or not id-right is
a domain name. It might be or it might not be. In the event
that it is not, RFC 2822 is silent on whether or not case
matters. Under RFC 822, the RHS of a msg-id was always a
domain, and as domain names are always case-insensitive, the
two msg-ids above would match under RFC 822. Under RFC 2822,
one cannot tell whether or not they match.
There are other, related issues as well.
