Description:
------------
I tried to refractor email validation code to use the 
FILTER_VALIDATE_EMAIL filter instead of a regex. Our Unit tests failed,

because it marked the following email addresses as invalid:

e.x.a.m.p.l.e.@example.com
a@com






Reproduce code:
---------------
<?php

$wacky_but_valid_emails[] = 'e.x.a.m.p.l.e.@example.com';
$wacky_but_valid_emails[] = 'a@com';


foreach( $wacky_but_valid_emails as $email ) {
        print "$email : ";
        $result = filter_var($email, FILTER_VALIDATE_EMAIL );
        var_dump($result);
}

?>

Expected result:
----------------
e.x.a.m.p.l.e.@example.com : bool(false)
a@com : bool(false)

Actual result:
--------------
e.x.a.m.p.l.e.@example.com : string(e.x.a.m.p.l.e.@example.com)
a@com : string(a@com)
