Bypass/Whitelists:

To bypass spam checking for certain external addresses or server IP addresses:

1. In the MailMarshal Web Console, navigate to Policy Elements > User Groups.

3. Optionally navigate to Policy Elements > IP Groups, create a new IP group, and add IP addresses or ranges you want to whitelist.
4. Navigate to to Email Policy > Package Policies > Standard Protection.
5. Click User Matching next to the "Anti-Spam (Inbound)" Policy.
6. Click "Apply to users matching...", and then check "Except From group".
   
   
7. Click group.
8. On the group window, select (check) each of the groups you created above, and use the arrow to and move them to the "Matching" list.

6. Click Save, and then close the Preset Group window..
