In Javascript:
-------------------------------
# http://www.webmaster.ucr.edu/blog/index.php?p=9&more=1&c=1
#
function isValidEmail(addressS)
{
    emailRegexp = RegExp('^[A-Za-z0-9._\-]+[@]\
([A-Za-z0-9\-]+[.])+(com|net|edu|us|gov)$', 'i');
    if (emailRegexp.test(addressS))
    {
        return true;
    }
    return false;
}

And in PHP, its almost the same
-------------------------------
# http://www.webmaster.ucr.edu/blog/index.php?p=9&more=1&c=1
#
function isValidEmail($address)
{
    return preg_match(\"/^[a-z0-9._\-]+[@]\
([a-z0-9\-]+[.])+(com|net|edu|us|gov|uk)\$/i\", $address);
}
