The function has a filter which tells you where it failed you could use to catch the exit and run your own validation and return true instead of false.
// LOCAL PART
// Test for invalid characters
if ( !preg_match( '/^[a-zA-Z0-9!#$%&\'*+\/=?^_{|}~\.-]+$/', $local ) ) {
return apply_filters( 'is_email', false, $email, 'local_invalid_chars' );
}
Psuedo-code…
add_filter( 'is_email', 'my_email_validation', 10, 3 );
function my_email_validation( $return, $email, $context ) {
if( 'local_invalid_chars' != $context ) {
return $return;
} else {
// Validate $email however you please, return false or true
}
}
If you think this should be part of core, head over to Trac and open a ticket. http://core.trac.wordpress.org/
Hope that helps.
Also note, that if you do this you will skip the domain validation parts of the is_email function and will need to include that validation in your function.
Hi Jackson, thanks for the response.
Im hammering away at the code now.. will post-up what I have and look forward to comments.
Cheers
Am I correct i thinking that I will need to run all of the validation that follows the local part in the ‘is_email’ function ?
That’s correct.

Might do just what you want.
Hmmm.. Ive tested it, and no-dice.. still errors – sadly.
But it cant be far away from what I need..
*keeps going*
Ran up against this same problem a while ago, and this was the solution I came up with. Put the following code into your functions.php file. Pulling the email address from the post variable was the only way that would work.
function email_validator($email_address='' ){
//Validator will fail on apostrophes when is_email is called if we don't check the POST var instead of $email_address
$user_email_address = ($_POST['email']) ? $_POST['email'] : $email_address;
if(filter_var(stripslashes($user_email_address), FILTER_VALIDATE_EMAIL)){
return stripslashes($user_email_address);
} else {
return false;
}
}
add_filter('is_email', 'email_validator', 1, 1);
add_filter( 'sanitize_email', 'email_validator', 1, 1 );
