Add Exceptions To your List
Check the box in the Options section ("Bypass this setting for messages received from addresses or domains within these approved sender lists") to set up a new approved sender list or to reuse a list that you have already created. An approved sender list enables you to approve messages from specific addresses or domains. When you set up an approved sender list in the Blocked senders setting, messages from domains or email addresses in the list will bypass the Blocked senders setting. Note: Other settings may still cause the message to be blocked.
