[Mailman-Users] Newsgroup interface - upload to mailman not working

[David Beaumont]

We interface to a newsgroup, details:

"The hostname of the machine your news server is running on. 
news.annexcafe.com
 
The name of the Usenet group to gateway to and/or from. 
annexcafe.dba.bargemain"

Emails are transferred to the newsgroup OK.  Until September last year
newsgroup postings were picked up by mailman and distributed as emails.
However since then that bit has stopped working, any ideas why?  Our
supplier says the newsrunner process is running.  

Thanks

David
