To prevent information leakage and block off malicious emails, administrators can set data protection rules to scan incoming and outgoing emails.
- 1.Set a data protection rule
Log in to Admin. Under the Feature Management on the left, click on Mail > Security > Data Protection > New Rule.
Enter the rule name, description, and its application scope.
Tips: A protection rule can be applied either to the entire company or to a specified range.
For rules applicable to a specified range, select one or more options, including Departments or members, Public mailbox, and Mailing list.
Select the triggering events of a rule. There are 4 available options:
- •Receive external emails
- •Send to external mailboxes
- •Receive internal emails
- •Send to internal mailboxes
When a triggering event occurs, the email will be checked against triggering conditions. With triggering conditions, you can check whether a particular section of an email contains or doesn't contain certain keywords.
Select the section of an email to be checked from the 4 available options, including Email subject, Message body, Sender, and Recipient or CC, then enter the keywords you want to look for.
Upon setting the triggering events and conditions, set the action to be taken if risks are detected. You can select from the two options below:
- •Reject email: Emails flagged for safety breach will be blocked from being sent or received.
- •Quarantine email: Emails flagged for safety breach will be blocked and handled by the administrator.
Click Confirm to finalize the rule.
Tips: Set up to 10 rules for each triggering event, and 10 triggering conditions for each rule.
- 2.View data protection rules
Go to the Data protection rules list, and click on a rule to view its details.
To modify a rule, click Edit. Enable or disable a rule using the toggle switch in the Data protection rules list or the details page.
Emails that have triggered a quarantine action will be stored in the Quarantine Area, and will be reviewed by the administrator. Administrators can query emails under quarantine in 3 ways:
- •Query by email status including In quarantine, Passed and Rejected.
- •Query by keywords in email subject or body text.
Click on a quarantined email to view its details, including its content and the rule triggered.
The administrator can select Rejected or Pass to decide the outcome.
Note: An email will only be sent or received if it's passed.
