I have the following code:

$config = array(
   'auth' => 'login',
   'username' => 'domain\user',
   'password' => 'password',
   'ssl' => 'tls',
   'port' => 25,
);

$tr = new Zend_Mail_Transport_Smtp('192.168.101.11',$config);
Zend_Mail::setDefaultTransport($tr);

$mail = new Zend_Mail();
$mail->setBodyText($text);
$mail->setFrom('noreply@domain.com');
$mail->addTo($user->getEmail());
$mail->setSubject('Email subject');
$mail->send();

When I try to connect using what should be the correct credentials I get the following error in the log:

2010-10-12T13:00:59-07:00 ERR (3): AdminController::emailPassword - 5.7.1
2010-10-12T13:00:59-07:00 ERR (3): AdminController::emailPassword - #0 /usr/share/php/Zend/Mail/Protocol/Smtp.php(261): Zend_Mail_Protocol_Abstract->_expect(250, 300)

        #3 /usr/share/php/Zend/Mail.php(1178): Zend_Mail_Transport_Abstract->send(Object(Zend_Mail))
...

When I try to connect and send an email using a definitely bad password I get the following error:

2010-10-12T13:03:52-07:00 ERR (3): AdminController::emailPassword - 5.7.3
2010-10-12T13:03:52-07:00 ERR (3): AdminController::emailPassword - #0 /usr/share/php/Zend/Mail/Protocol/Smtp/Auth/Login.php(95): Zend_Mail_Protocol_Abstract->_expect(235)

#5 /var/www/mreserve/application/controllers/AdminController.php(458): Zend_Mail->send()
...

My problem, I don’t really know how to diagnose these errors. Where do I look up what 5.7.1 and 5.7.3 error codes are described, etc? Google wasn’t helping me too much. When I plug in the credentials for my personal GMail account I am able to send mail just fine, so I know that I can send emails when configured correctly.

A few other possibly helpful tidbits, I am trying to send from a company Exchange that has created an email account for this user, I am trying to send to an email outside of the domain, and I don’t have a lot of access to the exchange server- other than a few screenshots on how they set up their email clients.

    These are NDR (Non Delivery Report) codes for Exchange server.
    Here is a (rather old) blog entry describing them, and another page listing the sames codes for exchange 2007.

    5.7.1 Error code

    “permission problem”, which could point to a:

    • a SMTP relay problem. Your account is not authorized to send emails to another domain.
    • a sender/receiver problem. Your account is not authorized to send emails to a discussion list (because your account is not a member of it)
    • other specific restrictions on your account.

    IMHO, only the SMTP logs can tell the exact cause.

    5.7.3 Error code

    “sender prohibited” or “Not Authorized, security problem”, depending on the source; could be consistent with wrong password submission.

    Hope this helps.
