You can configure Deep Discovery Email
Inspector
to add a digital signature to outgoing message headers to prevent spoofing. Recipients
can verify
that the email messages from a specific domain are authorized by the domain's administrator
and
that the messages, including attachments, have not been modified during transport.
ImportantIf you configure Deep Discovery Email
Inspector
to sign an incoming message that already contains digital signatures from other email
services
(for example, Gmail) or MTAs, Deep Discovery Email
Inspector
removes all existing signatures from the message before adding the new signature and
sending the
message.
