Mode Switch option
Select the mode from the following for which you want to apply SPX Configuration and manage SPX Templates:
SPX Configuration
Default SPX Template
Select the default SPX Template. SPX Templates can be created from Device Configuration > Protect > Email > SPX Encryption . Default Template is used if any user explicitly SPX-encrypts an Email and no template is selected in Content Scanning Rule.
User can SPX-encrypt an Email by:
Manually setting the Email header X-Sophos-SPX-Encrypt to yes.
Installing the Sophos Outlook Add-on and clicking Encrypt before sending the Email.
