A big AMEN to that! A lot of things could be resolved at the ISP levels. Although I bet dollars to doughnuts it ain't the admin's fault. Managment probably has there hands tied. I think home users should have certain ports blocked at the ISP level, UNLESS they request otherwise. Then they get them open for no charge, but the ISP will know which people to monitor traffic on. This way the majority of people with trojan'd boxes would go away. > > The bar is being raised for mail service operators.

But it appeared as though I had found the diamond in the rough on the other end of the phone. The guy knew his stuff.
