hmm... i would have thought that specifying a filter 
action of "Stop Processing" or "Delete" would have 
prevented the message from being sent, however, upon 
brief testing, i have found that this is not the case. 
It looks like the 'filter does indeed stop processing 
the message' but then evolution sends the message as a 
'post filter' scenario. 

couple of solutions:

* Specify an SMTP in evolution that is an SMTP server 
  that is a dummy SMTP server you have written. The server
  will need to do nothing other than accept the message 
  and ignore it!

* Write a wrapper for sendmail (i don't know how Evo decided 
  where 'sendmail' is located - perhaps the Evo people can 
  enlighten us here)... if its as simple as setting an environment 
  variable so that evo calls your script instead of sendmail, then 
  you can write your own wrapper (and no need for output filter even 
  in that case, as every message will go via your wrapper anyway). 
  If you can't easily specify your own script, then you might need 
  to replace /usr/sbin/sendmail (or similar) with your wrapper 
  (and still no need for output filters).
