Regex is a bad way to validate an email address. You risk to run out of resources (some very long regexes), annoying people with real but weird email addresses and people will still register using throw away email accounts. If you need to know for sure that email is valid, make 2 step registration with a link sent to said email address with one-time ID'd link back to your validator. If however you don't run a bank or serious commercial operation, take pretty much any email thrown at you and your emailer should remove bouncing ones from its database.
