So, trying to send articles from my BBBS/2 system to my news server using NNTP   
   (which runs Leafnode on Debian 9) and am getting this error that I can not seem   
    to fix:   
      
   {2}[c:\bbbs] bbbs bnntp r news.os2bbs.org Trying to connect to NNTP server   
   news.os2bbs.org. Connected to server.   
   Reading group comp.os.os2.   
   Reading group comp.os.os2.networking.tcp-ip. 180211 18:42 Posting of message

                441 Post rejected, formatting error: Message-ID: header does not   
                have domain name part.

   Any thoughts and ideas would be greatly appreciated,
