Not in the database, See I am giving an example, Like if you enter a email address and click on the submit button, we are suppose to check the entered email address is correct or not. I am not talking about the validation its about the domain checking.
example, test@gmail.com
test@yahoo.com
te@hotma.il.com
test@rediffmail.com

You cannot validate email addresses beyond checking that the format looks correct. And since there are many different providers it is impossible to know them all.
