   apparently you're not getting the modified duplicates... the ones with the   
   time stamps changed to :00 or to even seconds... then there are the ones that   
   have had the body modified... i've seen MSGIDs with a trailing space added to   
   them... that leads to MSGID checking only systems to fail the detection unless   
   they specifically trim whitespace... rewrapping of the body is another flaw   
   causing dupes to not be detected properly...   
      
   one of my comments was about nothing in fidonet being able to detect these   
   types of modified messages because they have been modified in ways no one   
   thought they would ever be modified...   
      
   IIRC, db uses the header and first 40 bytes for its dupe detection... i'm not   
   exactly sure on the details but i know that they greatly influenced me to have   
   my software place the MSGID as close to the beginning of the control lines as   
   possible so that db would not detect messages posted within one second as   
   dupes... this was especially important when testing at 100+ posts per   
   second... are you willing to share information about how db does its dupe   
   detection so others can understand more? please?
