	Why does that not supprise me, We have a Mail server here, (a
closed relay) but if you look at the relay block log (We're using EXIM
rejectlog)  somone tests the relay block about every 6 hours!!!! This is
on an Fixed IP BT ADSL connection.
	Basically unless you have a very good reason for running SMTP and 
know that its safe (ie relay blocked except to your own users) Keep port 
25 firmly closed. Until somone comes up with a better protocol than SMTP.
