Pass return-path additional parameter in wp_mail

Yes! There’s a plugin that does this, and it’s very simple. It uses the phpmailer_init to adjust the $phpmailer object. This is the code it uses:

if ( ! function_exists( 'wp_mail_returnpath_phpmailer_init' ) ) {
    function wp_mail_returnpath_phpmailer_init( $phpmailer ) {
        // Set the Sender (return-path) if it is not already set
        if ( filter_var( $params->Sender, FILTER_VALIDATE_EMAIL ) !== true ) {
            $phpmailer->Sender = $phpmailer->From;
        }
    }
}

add_action('phpmailer_init','wp_mail_returnpath_phpmailer_init');
