That was the original question, is it an implementation
getting it wrong, or something else.  So far we know

* it's no problem at the old sender (un.org)
* it's no problem at the new sender (googlegroups)
* it's no problem with SPF HELO checks
* it's no problem with SPF MAIL FROM checks
* it's no problem with Sender ID confusions
* it's no problem with rejecting FAIL 
* it is a bogus FAIL checking the wrong address

What we don't know is if this a broken implementation,
as in "some code got it wrong", or a broken setup, as
in "code is fine, but operator arranged for the wrong
address to be checked".  

The latter case could turn out to be "code is dubious,
as it supports to do something stupid"...

IBTD because I'd like to know if this is dubious code.
If we know this we could put a warning on the SPF site.

SPF users should never have to worry about such issues,
and if an implementor confused MAIL FROM with 2822-From
(s)he belongs into a "hall of shame" on the main page -
hopefully convincing other implementors that this isn't
how they want a link to their code.
