Forget about default textbox restrictions, you can create sprites atop of the textbox

The regex defines what can and can't appear in the email address; this part:

^[A-Z0-9._%+-]+

...defines what characters can appear before the "@". The "@" ensures that there has to be an instance of the "@" symbol.

This part defines what can appear after the "@":

[A-Z0-9.-]+\.[A-Z]{2,}$
Note that neither of these parts allow "@"

This isn't the only regex that can validate emails. If you google "regex" and "email" you will find a whole bunch of other examples, some more thorough than others.
