email validation

[anonymous]

The following expression I am using to validate an email.
However when empty spaces entered at the end of email it
is recognized as invalid email. How do I fix this problem?
^([0-9a-zA-Z]([-.\w]*[0-9a-zA-Z])*@(([0-9a-zA-Z])+([-\w]*
[0-9a-zA-Z])*\.)+[a-zA-Z]
{2,9})$

Here's an easier method....
Just go to http://regexlib.com/ and lookup "e-mail validation" and copy one
of the expressions already written there.

I could not find any expression which will validate email
liek this:
<[email protected] >.
As you can see I have some empty spaces after actual email
and I can't find the expression to validate email as well
as taking the space out.
Thanks

You could always do a trim on the email field

I am a little bit confused...here is my code... where I
should trim???
<asp:RegularExpressionValidator id="reEmail"
runat="server" CssClass="error_message" ErrorMessage="You
must enter a valid Email address."

ControlToValidate="txtEmailAddress"
ValidationExpression="^([0-9a-zA-Z]([-.\w]*[0-9a-zA-Z])*@
(([0-9a-zA-Z])+([-\w]*[0-9a-zA-Z])*\.)+[a-zA-Z]{2,9})
$"></asp:RegularExpressionValidator>
