my asp site uses cdonts for users to email each other. this works fine but recently this has been raided by spammers, in my case the african spam scam of 'my late husband left me several million US$ and need help transfering out of the country' etc. i figured i could solve this by not delivering any messages containing both terms 'million' and 'US$' would do the trick without effecting the genuine messages. but i'm not sure how best to go about adding this filtering process. can anyone help? thanks in advance.
