Validator for EmailID

Question

Hi,

I am using RegularExpressionValidator to validate EmailID where ValidateExpresion  is::

\w+([-+.']\w+)*@\w+([-.]\w+)*\.\w+([-.]\w+)*

Actually i want to validate EmailID that can also contain spaces.

example::

<    [email protected]    >,<[email protected]>,<  [email protected]>
I want to validate all of the above Email IDs as Valid.

Please help me

Thanks in advance
