Go to Filter Rules > Geoblocking.
In the Sender Email Exemptions: table click Add... and the Add Sender Email Exemption window displays:
Complete the fields as follows:
Sender Email: Email address you want to exempt from geoblocking rules.
Comment: An optional comment on this email exemption.
Click Save to save this email exemption, or Cancel to discard.
Once an exemption has been added, it can be edited or deleted. Click the edit 
icon to edit an exemption, or click the delete 
icon to delete an exemption.
