Update fMailbox.php handling 5.6+ Security

As of PHP version 5.6 there is much stricter security checking being done on various levels. Flourish's excellent Mailbox class unfortunately isn't up-to-date enough to handle the new restrictions by default. This fix is simply a fallback to allow for its previous level of functionality. It bypasses the new security implementations that PHP 5.6 brings to the table, but users of Gmail's mail server, or users of shared hosting will be able to continue to use this library with the class as expected. (It has to do with domain mismatch.)
