check out the above URL, many types of Regular expression are available for Email validation. You might need to modify slightly.

I am not good at regular expressions, but try the following

^(\w\[?)([\w\-\.]+)@((\[([0-9]{1,3}\.){3}[0-9]{1,3}\])|(([\w\-]+\.)+)([a-zA-Z]{2,4}))(\[?)$

Its the simplest format!

Original reg. expression was

^([\w\-\.]+)@((\[([0-9]{1,3}\.){3}[0-9]{1,3}\])|(([\w\-]+\.)+)([a-zA-Z]{2,4}))$

I tried to modify it slightly to match your requirement.
Somebody who is good at reg. exp. can update it to be more accurate :-)
