   The problem is, that the equals sign in PMMfilter triggers does not 
mean equality, but inclusion, i.e. "is the string included in the 
'Subject:' header?". 
  
   But the null string is found everywhere ... they should have added 
the .size property not only for the M i.e. Message tag (for Body and 
Attachment it is valid, too, I think), but also for all other headers, 
like "Subject:" in this case.

   It doesn't work, since the null string is at the beginning and at the 
end, or don't know what. 

   Now, the solution would be the P or PROGRAM tag; with the P-tag one 
can use one's own program to search the message for anything and return 
the result in another file, who's name is passed by PMMail in a second 
parameter. 

   I have written such a filter in VBS, but I have not yet managed to 
get PMMail to execute WSCRIPT.EXE with my script as parameter. I get 
messages that the program could not be launched, or that the path 
specification for it would be wrong, or else. 

   The filter condition would look like this: 

   P.<wscript  x:\bpsw\pmmail\PMMfilter_Subject-size.VBS> = "0"

   In a test environment on the command line, it works fine, but not 
(yet) from the filter engine of PMMail. Maybe I have to make a full 
VB-EXE out of the script. The length of the value on the "Subject:" line 
is written in the first line of the file given as second parameter. 

   I have also made a generalized version which takes the label of the 
header line as a first parameter; the filter condition would be like 
this: 

   P.<wscript  x:\bpsw\pmmail\PMMfilter_Subject-size.VBS Subject:> = "0"

   I did not yet try it in PMMail ... 

   Is anybody competent from Blueprint Software Works here who can tell 
with certainty if and how such filter P-tags could work?
