i can't beleive i defended NTL in a post
i wish they would but i think until the Goverment or EU force ISPs to do this then nothing will happen. I can't see NTL spending money on this or even installing anything for free unless they are forced into it.
Just think of that if all ISPs in the world had to have spam filtering then there would be no point in sending it and then the problem would go away.
