Thank you for taking the time to write to us, but this is not
a bug. Please double-check the documentation available at
http://www.php.net/manual/ and the instructions on how to
report
a bug at http://bugs.php.net/how-to-report.php

That domain might exist at your network.

Description:
------------
An email address is submitted to filter_var and returned as valid 
despite the domain being invalid. There are no single character top-
level domains.

Reproduce code:
---------------
$email = 'testuser@hotmail.co.u';
if (filter_var($email, FILTER_VALIDATE_EMAIL) === false) {
echo "Invalid email address.";
} else {
echo "Valid email address.";
}



Expected result:
----------------
Invalid email address.

Actual result:
--------------
Valid email address.
