The Encryption Service is Software-as-a-Service (SaaS) which provides secure delivery of your e-mail. E-mails which have [SECURE] as a tag at the beginning of the subject line will be encrypted and delivered to the recipient(s). Additionally, the administrator can create a policy with some condition and an action of 'Route to Encryption Service'. E-mails which satisfy the set condition(s) will be encrypted. Please enable outbound policy to send secure mails.
Once receiver receives a secure email, this email will contain an URL which will prompt receiver to register (create an account) with secure server, once the account is created receiver can view his/her account and can see the secure email.

The Email Security Appliance comes pre-configured with a filter to route mail to the Encryption Service. The filter is disabled by default and will have to be enabled. To do that, click Edit next to the filter name.
Place a check in the box next to Enable this filter: then click Save This Filter.
NOTE: It is recommended to update the Matching condition from 'starts with' to 'contains'. This will ensure email will be routed to the Encryption service as long as the subject line contains the Search Value.
Additional conditions can be added as long as the filter is configured to trigger if Any of the conditions are met.
NOTE: Any search value can be used and the values are not case sensitive; however, all other conditions must be met in order to trigger the filter and properly route the message. For instance, using the above conditions, a sender can prepend/append the subject line of an email with [secure] and the filter will be triggered. However, if the sender prepends/appends the subject with (secure), the filter will not trigger because use of parenthesis is not an accepted Search Value.
After the filter is enabled, all mail that meets the conditions of the filter will be routed to the Encryption service.
If the domain has an SPF record, include _spf.sonicsecuremail.com in the SPF record to ensure email routed through the Encryption Service is not flagged as spoofed.
