17433,localhost is not accepted as email domain,sanvila,,"Hi. Tried to install WordPress on a Debian machine not connected to Internet, only for testing purposes, so when the setup procedure asked me for an email address, I used mylogin@localhost. The setup procedure, however, rejected this as ""invalid"".

I think the bug is exactly in wp-includes/formatting.php, where it says:

        // Assume the domain will have at least two subs
        if ( 2 > count( $subs ) ) {
                return apply_filters( 'is_email', false, $email, 'domain_no_periods' );
        }

So: Could you please special-case ""localhost"" in is_email() so that it's allowed as email domain?

I guess the probability of someone using @localhost for email ""by mistake"" is extremely low, so this change will unlikely harm the average user.
