For a lots of standard mail components the easiest and most robust way 
to interface to them is running an executable separately for each message. 
In this case five seconds startup time may be a bit too much for sites 
with high load.

In this model the program is started once for multiple messages so a 
somewhat slower startup is not an issue.
