The RFC bit has been explained. But the pproblem is not yet resolved.

I think that the following header detection lines in postfix will spot
and reject this specific RFC violation for me:

#       RFC2822 violations
/^References:.*<EMEW-[\-\.0-9A-Za-z]*@vanderkooij.org>/ REJECT  Your
MessageID modifications of my MessageID violate RFC 2822 section 3.6.4
/^In-Reply-To:.*<EMEW-[\-\.0-9A-Za-z]*@vanderkooij.org>/        REJECT
Your MessageID modifications of my MessageID violate RFC 2822 section 3.6.4

As I can not judge what MessageID someone else is sending I know that
this format will be invalid for any message send by my mailserver so
those I can spot and reject as RFC violations.

Preferably I would like to detect all modifications so other programmers
falling into the same pit will be detected. But that requires a bit more
studying. (I might add it to the custom SPAM scanner I as thinking of ;-)

The only person to send out these modified MessageID's is Jules as far
as I have seen them. And his replies consistenly show up in the wrong
place in anything but the most simple thread in thunderbird.

I am sorry but in this regard I expect a programmer of email related
software to be specificly aware of the RFC. Most certainly after being
pointed to the current deviation.
