Whitelists:

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

1. In the SEG Console, navigate to Policy Elements > Groups.
2. Create a new External user group, and add email addresses you want to whitelist.
3. Optionally create a new IP group, and add IP addresses or ranges you want to whitelist.
4. Go to Customer Packages / Standard Protection.
5. Click User Matching next to the "Anti-Spam (Inbound)" Policy.
6. Click "Apply to users matching...", and then check "Except where addressed from groups". 
    
   
    
7. Click groups.
8. On the group window, click the arrow next to each of the groups you created above, and move them to the "selected" list.
    
   
    
9. Click OK, then OK again. 

Note: This whitelist will only bypass spam checking. If you wish to bypass specific rules, add User Matching to those rules directly.

Blacklists:

To quarantine all messages from certain email addresses or server IP addresses:

1. In the SEG Console, navigate to Policy Elements > Groups.
2. Create a new External user group, and add email addresses you want to blacklist.
3. Optionally create a new IP group, and add IP addresses or ranges you want to blacklist.
4. Go to Customer Packages / Standard Protection / Customer Blacklist (Inbound)

6. Click "Apply to users matching...", and then check "Except where addressed from groups".
7. Click groups.
8. On the group window, click the arrow next to each of the groups you created above, and move them to the "selected" list.
