Setting up encryption to be applied to outbound email that gets relayed through the Ironport appliance is quick and straight-forward. In a matter of minutes, you can get this feature up and running. Contact Ironport technical support if you have any questions or comments on how to use the encryption feature.
With the release of AsyncOS 5.5.0 for Email, the encryption feature is integrated into the Email Security Appliance. We've integrated the Encryption forum into the Email Security forum to reflect this change.
