Abstract

In some embodiments, techniques for computer security comprise receiving an email message; determining a sender of the email message; determining whether the sender of the email message is trusted, wherein determining whether the sender of the email message is trusted includes determining whether the sender of the email message is associated with a whitelist; retrieving domain-related information by performing a DNS query on a domain associated with the sender; based at least in part on the domain-related information, determining whether the sender of the email message is verified; determining whether the sender is both trusted and verified; and when it is determined that the sender is both trusted and verified, treating the email message as trustworthy, wherein treating the email message as trustworthy includes bypassing a classifier.
