  Well, I could not resist changing that script, and attached my
changed version. 

  The main changes are: 
  1) it works for the PROGRAM tag in a PMMail filter; 
  2) it does not read in the whole message, but only the header
lines
       and does not change the original mail file;
  3) it does not check every header, but only RECEIVED: headers; 
  4) the basic mechanism of the blacklisting is explained;
  5) a debug mode is added (give "debug" as third parameter). 

  I think, it would run much faster than the original version by
Winfried Tilanus. 

  Configure the script in a PMMail filter with a complex condition
like this: 

  PROGRAM.<X:\your_path_to_it\spamcheck.cmd> = "X-Spam-Warning"

  Where X is the drive where "your_path_to_it" is the path to where
you put the script. 

   This condition can, of course, be combined with other
conditions, like "h.subject = 'Viagra'" or "h.subject = 'mortgage'"
and so on. 

  You may change the script if the checking is too strict -- in the
current version it also acts on IP-addresses which are only "Open
relay", but which may be valid sender hosts. There is a comment in
the place where that change should be made.
