Yes, I thought of that.  But I also thought that instead of using the
local MTA, we could use another server.  Yes, that is similar to what
monit would do, but I was just wondering, since there is already a test
in MailScanner that raises a flag when the treshold is hit, how easy it
would be to call a function that would send an e-mail using an external
mail server.

That is indeed a good idea.
