   Hello Maurice Kinal!   
      
   ** On Monday 12.04.21 - 20:52, you wrote to me:   
      
    MK> Here is an official test of duplicate MSGID serial numbers from two   
    MK> different addresses to see if it shows up as a false dupe..   
      
      
   My system has both of these:   
      
   [1]   
      
   EMP: /FIDO/ASIAN_LINK   
   ABS: Maurice Kinal@1:153/7001   
   BET: MSGID   
   ROT: 2:221/1!153/7001 757 221/6 1   
   MID: 1:153/7001 8QIOgQad   
   EDA: 20210412014100W+0   
   LEN: 2042   
   BEZ: 2:221/1.58@fidonet ef514dc6   
   MAILER: GNU bash, version 5.1.4(1)-release (x86_64-motorshed-linux-gnu)   
   X_C:   
   X-XP-NTP: 30   
   F-TO: August Abolins   
   X-XP-Charset: UTF-8   
      
   [2]   
      
   EMP: /FIDO/ASIAN_LINK   
   ABS: Maurice Kinal@1:153/7001.2989   
   BET: anyway the wind blows   
   ROT: 2:221/1!153/7001 757 221/6 1   
   MID: 1:153/7001.2989 8QIOgQad   
   EDA: 20210412205200W+0   
   LEN: 811   
   MAILER: GNU bash, version 5.1.4(1)-release (x86_64-motorshed-linux-gnu)   
   X_C:   
   X-XP-NTP: 30   
   F-TO: August Abolins   
   X-XP-Charset: UTF-8   
      
      
   But the subtle difference in these two lines:   
      
   [1] == MID: 1:153/7001 8QIOgQad   
   [2] == MID: 1:153/7001.2989 8QIOgQad   
      
   Perhaps you need to keep the "address" part the same for a valid     
   test.
