New Usenet Post Filter

Today a new usenet post filter has been enabled on our news server. The primary purpose of this filter is to clean out SPAM - which we do not tolerate. The filter is rather aggressive and will also reject eg. HTML postings - so make sure your news reader is configured to post plain text articles. If you by any chance find that a legitimate, correctly formatted (See RFC 1036 ) message from you gets rejected, please let us know.
Update: Due to a misconfiguration, the first messages posted after the implementation were lost. The configuration has now been corrected, and all affected users have been notified.
