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(at)stonehenge(dot)com> is a valid email address. (Go
ahead, try it... it has an autoresponder.)
