A SpamAssassin process launches for each mail received as it is
received - so monitoring of the pids is not a good solution because
this a multi-tasked operation.

I perform similar stuff with fetchmail and SpamAssassin and I can't
think of any sensible way to do what you are trying to do. I have
never seen SA take any real amount of time to check a message, so I
wouldn't worry too much about it.

If I were doing this, I might use the output of fetchmail to indicate
thenumber of messages received and then add a fixed amount of sleep
for each message. For example, if I received 3 messages, I'd sleep for
3 seconds...
