Writing in his bog, Meng Wong lead developer of the anti-spam authentication scheme, SPF, has warned that it is becoming increasingly impossible for spam filters to work properly.
He said that the final solution to the phishing problem requires that people use a whitelist-only, default-deny setting for all email.
He said that the use of whitelist only systems are common for instant messaging and VoIP traffic, but there was a cultural resistance to whitelist-only email. However Wong said that moving to effective whitelist only email was the only way to kill phishing.
He said that if this happened, it was vital for punters to make sure that their white lists were as wide as they could be. So that the openness of the net was not too badly walloped. µ
