You could post it to the new NQC list/group, which is now up & running.

Here it is:

The crynwr.com server doesn't? Or the lugnet.com server doesn't? AFAIK, both
send copies of messages out to everyone on the distribution list (including the
original sender), but they don't echo copies back to each other (or else there
would be an infinite mail loop).
Anyway, I figured out why 5 of your messages didn't make it into newsgroup
immediately immediately upon being received. (Only messages from you were
causing a problem, BTW -- not any messages from other people...makes ya feel
extra special, huh? :)
I have a regex in the .procmailrc (incoming mail filter configuration file)
which discards failed delivery attempt notification messages, auto-response
vacation messages, bounce messages, etc.:
^FROM_MAILER
According to the procmailrc manpages, ^FROM_MAILER is an abbreviation for a
larger regex:
If the regular expression contains `^FROM_MAILER' it will
be substituted by `(^(((Resent-)?(From|Sender)|X-Envelope-
From):|>?From )([^>]*[^(.%@a-z0-9])?(Post(ma(st(er)?|n)
|office)|(send)?Mail(er)?|daemon|mmdf|n?uucp|r(esponse|oot)
|(bbs\.)?smtp|serv(ices?|er)|A(dmin(istrator)?
|MMGR))(([^).!:a-z0-9][-_a-z0-9]*)?[%@>\t
][^<)]*(\(.*\).*)?)?$([^>]|$))' (a stripped down version
of `^FROM_DAEMON'), which should catch mails coming from
most mailer-daemons.
Now that's one behemoth regex. It looks valid, but it has a small bugaboo:
In addition to catching mails from most mailer-daemons, I believe it's also
matching the following header in your messages:
X-Envelope-From: postmaster@jpsc.co.uk
Maybe it's a bugaboo in the regex for thinking that 'postmaster' is always a
server-generated poo-poo message, or maybe 'postmaster' technically shouldn't
be appearing in X-Envelope-From on your messages...I'm not an SMTP guru so
I'm not sure. I'll have to figure out a workaround regardless.
In the meantime, I've been sending your messages through the newsgroup gateway
by hand, so they've showed up a bit late, but rest assured that they haven't
been lost.
