PortalGuest - Email Validation

[Kalimoz]

Hello all,

I know that in ISE is possible to not allow guest with an email address from X. But i don't know how to disable all the free domains like hotmail, google, yahoo, etc.

I have an example in screenshot, is it like that?

If that is possible how can i do it? 

Thank you in advance

As stated in the example under the text box, the syntax should be:

hotmail.com, gmail.com, x.com
