Abstract
A computer-implemented method includes generating behavior patterns based on historical behavior of a plurality of emails. The method further includes receiving an email message from a sender, wherein the email message is withheld from delivery to a recipient. The method further includes extracting a plurality of features from the email message. The method further includes determining whether content of the email message matches at least one criterion for suspicious content.
