If an IP address tries to relay through VPOP3 twice (2 x 100), tries to log on 5 times with an invalid password (5 x 50), tries to send to 12 local addresses which don't exist (12 x 50) within an hour, then the total score will be 200 + 250 + 600 = 1050, so that IP address will be blocked for 30 minutes. | If an IP address tries to relay through VPOP3 twice (2 x 100), tries to log on 5 times with an invalid password (5 x 50), tries to send to 12 local addresses which don't exist (12 x 50) within an hour, then the total score will be 200 + 250 + 600 = 1050, so that IP address will be blocked for 30 minutes. | ||
