I agree with all the other replies to your post about the caveats on
validation. However, I have found some uses, e.g. client-side
validation in forms to catch user typos. In Javascript, I have used
the re.

"^\\w(\\w|\\.\\w)*@\\w(\\w|\\.\\w)*$"

I have not tested this in Python but it should need only minor mods,
if any...since you mention Web forms in your post, it may be that you
can do this browser-side.

Hope this helps
