easysw.com is using newsd, which is broken by design, in that it replaces
the Message-ID. Leafnode thus cannot detect it has succeeded in posting
the article (it doesn't trust the 240 message from the server), and
retries.

Replacing the Message-ID is a mind-boggingly stupid practice that has
caused several dupe (duplicate message) floods already, and the only thing
I can and will do is prevent posting to newsd servers.

Please complain to easysw for not fixing this bug in several years (it's  
easily identified in their bug tracker for newsd, but I'm not going to  
register an account there).
