The purpose of this rule action is to protect sensitive data in email messages sent
by users in your organization.

NoteThis action only applies to outbound rules.
For outbound messages with DKIM signing enabled, if you also apply this
encryption action which causes mail body change, these messages may not pass
downstream DKIM authentication.

Actions in this class encrypt the message and then
queue it for delivery. This is a non-intercept action, but no other actions can
be taken on the target message after this rule is triggered. This action has the
lowest priority of all actions, but when triggered it is always the final rule
run before the message is queued for delivery. If more than one rule in the rule
set is triggered, the rule that uses the encrypt email action will always be
triggered last.
In most cases, a rule to encrypt email messages will be based on one of the
following:
-
Specific senders or recipients of the message (for example, a rule that encrypts all email sent from Human Resources or the Legal department)
-
Specific content in the message body
-
Sensitive data contained in the message
Procedure
- From the
Intercept
section of the Action page, select Do not intercept messages - From the
Modify
section of the page, select the Encrypt email action.
