That's OK.  :) I'm hoping someone from Cisco will read this.  I would like this to be a feature in a new release.

I can ADD ONE.  I was asking if there is a way to add multiple.  I have over a hundred domains from our customer list that I want to whitelist and adding them each individually is tedious.  I wish Cisco would have added this as an option to the Block...

Nope, not working for me.  I drill down to:--> Mail Policies--> HAT Overview--> WHITELISTAfter I click WHITELIST, I get the option to add a sender."Enter the hosts to add. CIDR addresses such as 10.1.1.0/24 are allowed. IP address ranges such as 10.1...

Let me rephrase my question.  Can I add multiple domains or FQDNs to the whitelist?  I know how to add just one through the GUI and that's all that it will allow to my knowledge.
