Whats wrong with PGPtools? (A lack of documentation. Been a
while since I looked, but I think it lacked a high level interface.
The low level stuff is great, but on the mac, I can send an Appleevent

response.

Who needs real time? The servers are often bogged down and
don't respond in real time anyway. The following procmail works fine.
Theres also a short shell script at the end.
