How does PGP Universal Gateway Email determine that an email requires encryption?
PGP Universal Gateway Email obeys encryption policies specified by the PGP Universal administrator in PGP Universal Server. The administrator can choose to encrypt messages on the basis of the message sender, the message recipients, and even the content of the message itself. These policies allow PGP Universal Gateway Email to automatically determine which messages require encryption without requiring any action on the part of a user to trigger encryption.
