We recommend to review the AntiSpam and Email Quarantine Guides as these provide further details on the deployments tasks that administrators need to take to deploy and manage the service:

• Email AntiSpam Administrator Guide
• Email Quarantine User and Administrator Guide

Follow these steps to deploy email quarantine to specifically targeted users (for example, key personnel). Caveat: Emails from domains that publish a DMARC policy may be rejected, quarantined or tagged if they fail validation, according to the sending domain’s DMARC policy.  If the emails are quarantined, your end users may automatically receive an Email Quarantine welcome message and summary notification.”

Create Anti-spam group

Group settings are not available by default. Contact the Symantec Support team to be provisioned with this feature. When you define a group for the Anti-Spam services, you can apply customized detection settings, actions for suspect mail, and approved and blocked senders lists to the members of the group.

There are two limits to consider when managing Anti-Spam groups. The maximum number of groups per domain is limited to 20. The maximum number of users within these groups is limited to 150 across all groups, per domain.

1. Select Services > Email Services > Anti-Spam.
2. From the domains drop-down list, select the domain where you want to create the group.
3. Click the Groups tab.
4. Click Create new group. The window is displayed.
5. In the Create Group dialog box, enter a Group Name of up to 50 characters.
6. Group names can only contain alphanumeric characters and spaces.
7. To display the email addresses in the domain, leave the search box blank and click Search.
   The users in the domain are listed in the Available Email Addresses box. To reduce the number of addresses in the list, be more specific with your search text. Email addresses that are marked with * indicate users who have been granted control of user-approved and blocked senders lists.
8. Locate and select an email address to add to the group and click Add to group. The address is displayed in the Group Members box.
9. Repeat step 7 - 8 to add additional group members. When you are finished, or if you want to add group members by uploading a .csv file, click Save.
