netmail is totally different but offhand I think you are probably right
about the confusion software may or may not have about this issue. 
However, if the purpose of the MSGID is to facillitate dupechecking, and
nothing else, then I would think any node that uses point addressing to
avoid false dupes on a multiuser system would be a good thing even when the
pont address is not included in the Origin and perhaps shouldn't be.  But
that is just echomail and netmail has it's own checks and balances as far
as addressing is concerned.  No?

Seems to me somebody had a fix for the CHRS kludge years ago not too long
after fts-5003 reared it's ugly head.

 WvV> systems anyway that need the CHRS kludge for this.

I seriously doubt there ever will be a need, especially for UTF-8.  So far
for translating characters to/from 8 bit character sets, glibc's iconv
works great.  So far the CHRS kludge does nothing to facilitate that need
and that is a good thing.  :::patent pending:::

Life is good,
