All my messages posted to news.atkin.com show
up at yahoogroups but never on news.atkin.com.
When I post at yahoogroups using the same email
address though, the message makes it to the atkin
server.

This seems to be happening to a lot of people
as I see a lot of threads with missing first
posts when using news.atkin.com. These posts
do show up at yahoogroups. This means that
news.atkin.com users do not get to see
many messages.

I don't think this is a problem with my email
address since I doubt it has ever bounced. It
looks more like a misconfiguration in the atkin
news server.

I already changed newsreaders and the problem
is still there.
