Hi, because my field of research is machine learning/prediction, I'd suggest something that I already know is being used. A machine learning algorithm can be used to first detect some features specific to those kind of emails, we need some dummy data first. AND then we test it on some testing data set a which again contain similar emails set, to find out whether such a prediction holds true. This is usually applies to predict whether it is a SPAM or a HAM. Then those emails with possible phishing attacks can be redirected to the spam folder instead of the inbox.

I've changes the bid. Please visit the MATLAB section at my blog [login to view URL] section for some of my works. I regularly try updating it. Thanks.
