Sending mail via Gmail SMTP with PHP Zend error - UGFzc3dvcmQ6

I am trying to use the Zend Framework to send mail with Gmail, but have been unable to do so because it seems to reject the username and password (which I can use to login to gmail.com and with Outlook etc).

My PHP code is:

<?php

$tr = new Zend_Mail_Transport_Smtp("smtp.gmail.com",array('user' => '****@gmail.com', 'password' => '****', 'auth' => 'login', 'ssl' => 'TLS'));
Zend_Mail::setDefaultTransport($tr);

$mail = new Zend_Mail();
$mail->setFrom('sender@example.com', 'Some Sender');
$mail->addTo('****@hotmail.com', 'Some Recipient'); // my Hotmail ac开发者_如何学编程count
$mail->setSubject('Test Subject');
$mail->setBodyText('This is the text of the mail.');

try {
    $sent = $mail->send($tr);
} catch (Zend_Mail_Exception $e) {
    die($e);
}

?>

The exception thrown by Zend is:

exception 'Zend_Mail_Protocol_Exception' with message 'UGFzc3dvcmQ6
' in C:\Users\Admin\Documents\Wamp\bin\php\php5.3.0\lib\Zend\Mail\Protocol\Abstract.php:431

By going into Zend\Mail\Protocol\Abstract.php I found that the full $errMsg was:

UGFzc3dvcmQ6
5.7.1 Username and Password not accepted. Learn more at

I know that UGFzc3dvcmQ6 is "Password:" encoded in base64, but what does "fx12sm2756834wbb.59" mean, and how can I fix the error - should I be changing the port or ssl or auth or server or something? Or should I try it with another account?

You need to use SSL / OAuth for outgoing mail and Google has this page about how to set things up. They also have a page about problems sending mail that explains that you need SSL (and that links to another page on how to configure an email client).

I don't know about Zend mail, you probably can configure that to use SSL.
