Yes you can add to the whitelist what you like. The blocker has a CLI, but not IOS based. You can configure the blocker via CLI but I'm not sure how deep. But you can do everything from the webinterface and the webinterface is good and easy.

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. Wed, 04/08/2009 - 07:40

Yes you can.

I was just on my box and under my Whitelist I can "Add Sender". It is no problem to add more than one!

Nope, not working for me.  I drill down to:

--> Mail Policies

--> HAT Overview


After I click WHITELIST, I get the option to add a sender.

"Enter the hosts to add. CIDR addresses such as are allowed. IP address ranges such as are allowed. IP subnets such as 10.2.3. are allowed. Hostnames such as are allowed. Partial hostnames such as are allowed."

If I try to add more than one domain, i.e.,, or, I get this error:

A sender can be:
  • an IP address
  • a CIDR address such as
  • an IP ranges such as or 10.1.1-5.
  • an IP subnet such as 10.2.3.
  • a hostname such as
  • a partial hostname such as

What am I doing wrong? Wed, 04/08/2009 - 07:54

Try to add one domain, then the next domain, and so on...

Have you the newest OS?

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 Blocker.

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

Hi there,

I can think of a couple of possibilities. The first would be to export the HAT and take a look at it in a text editor. It may be obvious how to add multiple entries. I've never done this, though, so it may not be clear.

Blocker does have a CLI. I believe this command would do what you're looking for in batch:

listenerconfig edit IncomingMail hostaccess edit sendergroup ACCEPT Policy: “TRUSTED”

You can also use listenerconfig by itself for menu-driven CLI.

Let me know if that works.
