There's your problem. Somehow your watermark got set ridiculously high,

lower range, and from now until the end of eternity, you're not going to
find any "new" articles to pull out of the newsgroup and post to the list.
Ayup.
You're going to need to reset that watermark, if you want to get things
working again.

I've done that and things are indeed working. :) (See my other last post.)
You would need to talk to your news server administrator to see if they
did a re-numbering, or silently switched you to be pointed at a
different news server with a different article numbering, or what.
TCPDump is a wonderful thing.
This is one of those cases where it helps to be the administrator of
both sets of systems, so that you know what's going on under the hood on
both ends of the connection, and you have full control over what changes
are or are not made.

I'm working on setting up an install of INN for this and another similar
issue.
BTW, if you were using a server-style feed mechanism, there wouldn't be
a watermark issue.
You would instead track incoming messages by their message-id and date
headers, and if the message had a recent enough date header to be within
your chosen window of operation, and you had not seen that message-id
within that window of operation, and the message in question was posted
on one of the newsgroups you're subscribed to, then you'd accept the
message.
No watermarks here.
Of course, you continually purge old message-ids out of your database,
but you do want to keep them for a while after the window has expired,
in case someone takes an old feed and tries to re-submit it -- you want
to be able to reject all those old re-posted articles.
I recently installed INN on a personal server that I'm planing on using
for this and a few similar things. Seeing as how I've got gigs of space
and the fact that I'm only interested in about a dozen news groups, I
think I'll hold on to data for a very long time and not have any
problems with duplicates. I'm thinking that I'll end up setting up a
feed from INN to Mailman.
Please let us know how it goes.
(Re)setting the watermark took care of it. I now have 278 messages to
catch up on. <dull monotone sarcasm>ya!</dull monotone sarcasm>
