   Hi Maurice,

   Well FMail's dupe checking works a little bit different. When there is a valid   
   MSGID, it also uses the first letters of the From, To and Subject, for it's   
   dupe checking. So if they differ, while the MSGID is the same it's not   
   considered a dupe.   
      
    MK> Let me know and I'll make it so.   
      
   You are welcome to test it, but I already know how it works. ;)   
      
   Bye, Wilfred.
