How are you hoping to do this? The regex to validate an email address syntactically is pretty large: http://ex-parrot.com/~pdw/Mail-RFC822-Address.html And no, I'm not kidding. If your regex is smaller than that, you aren't validating email... you're validating something "kinda like email". For example, <fred&barney@xxxxxxxxxxxxxx> is a valid email address.
