Description

This is definitely not the final word on an email address regular expression, but it's useful and definately narrows down the options. There are however some known issues such as no literal top-level domain check.

I would add A-Z to the last a-z too, just in case someone use upper case on ".com"

So:
[a-zA-Z0-9._%+-]*@[a-zA-Z0-9._%+-]*\.[a-zA-Z]{2,4}
