i'm developing an app that i intend to run on a client's intranet. i want to ensure that only email addresses with the client's domain should be registered. how do i achieve this using regular expressions?

Are you using PHP 5.2 or above?

If so, you could use to validate the email address as a whole:
filter_var('bob@example.com', FILTER_VALIDATE_EMAIL);

And then using strpos and substr extract the domain element and do a string comparison to restrict the domain.

@lixamaga it's not safe because a user can disable javascript and submit malicious data, a server side filter, as blocblue suggested, is a necessary requirement.
