    This is entirely wrong!!. In the HAT you are adding HOSTS and not domains!! (the name states this even; HOST ACCESS TABLE, and not DOMAIN ACCESS TABLE).

    To whitelist a domain you need to know the hostname of the sending domain (putting in simple, the MX record(s)). You can also put the IP address of the sending host.

      Yes you should be able to add a single email address, highlight the question mark in the screen where you are adding a sender and it will show you the different formats it accepts.

      1. You are wrong

        As a Cisco engineer for the past 3 years, I can tell you that you should delete this article, this is all wrong and the answer that you are providing here as well….In the HAT we can only add hostaname/IP address. I know that the hostname is similar to the domain name, but it is not the same! This is why many customers are coming and asking questions why the email isn’t allowed when they are adding domains in the HAT……Check the guide or even there is a question mark when you are trying to add a sender, where it is saying what formats are allowed…..
