email_verified hook ?

Hi,
I have a custom requirement where new users should be approved by admin after registration. But if users have email from specific domains (a whitelist) like *@abc.com,*@dd.com then they should be registered automatically and assigned a wp role as well.

Is there a hook like um_after_email_verified which I can use so that when email is verified I can register users whit out approval.
Is it possible to do this ?
A functional hook code sample will be much appreciated.
