Don't validate email addresses.. The best way to go about it is to simply look for an '@' and no spaces, and then on your server validate by doing a domainname lookup.

A standard regex should be able to help, as it will disallow any characters other than the ones you specify. May want to take a look at: JQuery validate e-mail address regex

Regex only works if you go for very simple checking. A full verification that can catch all valid and invalid will take many pages of regex due to all the exceptions, unicode and more. – David Mårtensson Apr 18 '16 at 08:18
