   Hi Michiel,   
      
   On 2023-08-21 14:30:53, you wrote to me:

   I don't think that is a good idea...

   The current detection mechanism in FMail uses up to 7 bytes for the detection,   
   and an offset into the file for some archivers...   
      
    MvdV> OTOH... It may not be worth the effort this late in the game...   
      
   I don't think so either.

   I can't remember using it. I don't think it's still under development. A quick   
   google only gives me this: https://archive.org/details/GUS_170_ZIP so 1993...   
      
   Bye, Wilfred.
