Particular validation email

Hi guys, what I'm going to ask you should be easy for elgg expert users: I would like to implement a check on email while a user tries to register on elgg. This doesn't mean I want to validate email (I know that there is a PHP function (filter_var) but to validate only a particular kind of email hosting (I think I will have to write a PHP function to do it). What I would like to ask you is:

- you think is this way of acting right?

- what is the file I need to change? I checked but there is not a plugin who manages registration..

Thank you guys!
