Abstract
A method for applying policies to an email message includes receiving, by an inbound policy module in a protected network, message metadata of an email message. The method also includes determining, based on the message metadata, whether receiving the email message in the protected network is prohibited by at least one metadata policy. The method further includes blocking the email message from being forwarded to the protected network if receiving the email message in the protected network is prohibited by the metadata policy. In specific embodiments, the method includes requesting scan results data for the email message if receiving the email message in the protected network is not prohibited by one or more metadata policies. In further embodiments, the method includes receiving the scan results data and requesting the email message if receiving the email message in the protected network is not prohibited by one or more scan policies.
