Deliver to Junk folder (Available only for Office 365 Mail)	The Anti-Phishing engine marks the email as Spam by updating the Spam Confidence Level (SCL) to 9 (by setting value of header X-CLOUD-SEC-AV-SCL to True). The email will be moved to the Spam folder by Office 365 (with the proper Mail Flow rules), based on the configured action for SCL=9 (by default set to deliver the message to the recipients' Junk Email folder). For more information on SCL levels, see SCL.

Trusted Senders

Administrators can allow end users to trust senders and domains, so that spam emails sent from these senders are delivered directly to the users' mailbox.

Note - If the emails are classified as phishing or containing malware, they will still be quarantined.

To allow end users to trust senders:

1. Access the Harmony Email & Collaboration Administrator Portal and click Policy.

2. Open an existing Threat Detection policy or create a new one. See Threat Detection Policy for Incoming Emails.

3. Scroll down to the Spam section and select the Allow end-users to trust senders of Spam emails checkbox.

   

4. Click Save and Apply.

For information about how to manage senders trusted by end users, see Trusted Senders - End-User Allow-List.

Trusting Senders - End User Experience

When the user is allowed to trust senders, the user gets an option in the End-User Daily Quarantine Report (Digest) to trust senders / domains.

To trust a sender or domain:

1. Click Trust sender in the End-User Daily Quarantine Report (Digest).

2. Enter your email address and click Submit.

   

   The system sends an email notification with a verification code.

   

   Enter the verification code received from the email and click Submit.

   

   After successful verification, the system shows the status.

   

Graymail Workflow

Graymail consists of legitimate but often unwanted emails, such as newsletters and promotional emails, which many users find unnecessary, making it harder to find important messages.

The Graymail workflow moves these unwanted emails to a dedicated folder in the user's mailbox, ensuring a well-maintained inbox and enhancing productivity.

Note - This workflow is supported only for Office 365 Mail.

To configure the graymail workflow and customize the dedicated folder name:

1. Access the Harmony Email & Collaboration Administrator Portal and click Policy.

2. Open an existing Threat Detection policy for Office 365 Mail or create a new one. See Threat Detection Policy for Incoming Emails.

   The Edit Policy Rule page appears.

3. Go to the Spam section.

   

4. From the Graymail workflow list, select the workflow:

   • Do nothing

   • Same as Spam workflow

     For more information, see Spam Workflows.

   • Email is allowed. Deliver to Promotions folder.

     • In the Folder Name field, enter the folder name. The default folder name is Promotions.

       

       The system creates a dedicated folder in the user's mailbox.

   Notes: For Email is allowed. Deliver to Promotions folder workflow: The system creates a dedicated folder in the user's mailbox. It may take up to 24 hours to complete this for every 10,000 users. The folder name can only be customized once. If you want to change it later, contact Check Point Support. If a user deletes the dedicated folder, the system delivers graymail directly to the inbox, but only when the workflow is Email is allowed. Deliver to Promotions folder. To create the dedicated folder for users added recently to the existing policy or to recreate it for users that have deleted the folder, you must save the policy again.

5. Click Save.

End-User Experience for Graymails

The system creates a Deliver promotional emails to a dedicated folder rule in the user's mailbox and delivers promotional emails to the dedicated folder. Graymails (emails with the X-CLOUD-SEC-CP-GRAYMAIL header) are then routed to this dedicated folder.
