IETF tools list issues (was: Errata)

Hi, something with the IETF Tools list doesn't work.

GMaNe used to be subscribed as whatever <at> gmane.org,
and that worked at least until 2008-07-08:
<http://article.gmane.org/gmane.ietf.tools/1109/raw>

GMaNe identified this mail injected via GMaNe as spam.
That's kind of odd, if it's really spam, why forward
it to the list ?  The score says:

| X-Spam-Report: 5.5 points;
| * -0.0 SPF_HELO_PASS SPF: HELO matches SPF record
| * -0.0 SPF_PASS SPF: sender matches SPF record
| *  2.5 UNIQUE_WORDS BODY: Message body has many words used only once
| *  0.4 DNS_FROM_RFC_ABUSE RBL: Envelope sender in abuse.rfc-ignorant.org
| *  1.4 DNS_FROM_RFC_POST RBL: Envelope sender in postmaster.rfc-ignorant.org
| *  1.2 PRIORITY_NO_NAME Message has priority, but no X-Mailer/User-Agent

Unfortunately the IETF is listed as postmaster and
abuse ignorant since 2008-02-22, I didn't know that.

That my UA has no X-Mailer/User-Agent is IMO a bogey:

When posting via GMaNe the UA is a "Newsreader", and
it has a X-Newsreader, as "specified" in the NetNews
RFC (actually as "deprecated", and this RFC is still
waiting for its number, but that's another story. 

I've reported this "spam" as "unspam" while checking
something else:

Today the IETF Tools list "challenged" a new article
posted via GMaNe.  And *apparently* GMane used a new
address whatever <at> m.gmane.org (note the "m"):

<http://article.gmane.org/gmane.ietf.tools/1114/raw>
<http://article.gmane.org/gmane.ietf.tools/1115/raw>

Seeing the "challenge" I sent the "response" (1115)
directly (via GMail, not via GMaNe), but apparently
that didn't work, the original article is still lost
in space.

What is going on here, did GMaNe change its address
unilaterally ?  Why does the IETF C/R system not do
whatever it is trying to do ?  The RFC-I listings
are apparently an effect of a temporary glitch back
in February, I'll try to fix that.
