Description
S/MIME provides the capability for users to send and receive S/MIME email messages from wireless email devices. S/MIME and digital signatures provide assurance the message is authentic and is required by DoD policy. Without S/MIME users will not be able to read encrypted email and will not be able to encrypt email with sensitive information.
