Error 501 by sending mail using Swift mailer - php

Question

<?php
require_once '../plugin/swift/lib/swift_required.php';
// Create the Transport
$transport = Swift_SmtpTransport::newInstance('pod51003.outlook.com',587,'tls')
->setUsername('user#connect.polyu.hk')
->setPassword('pw')
;
// Create the Mailer using your created Transport
$mailer = Swift_Mailer::newInstance($transport);
// Create a message
$message = Swift_Message::newInstance('Wonderful Subject')
->setFrom(array('john#doe.com' => 'John Doe'))
->setTo(array('foodil#hotmail.com', 'foodil#yahoo.com.hk' => 'A name'))
->setBody('Here is the message itself')
;
// Send the message
$result = $mailer->send($message);
printf("Sent %d messages\n", $result);
?>
It turned out:
Fatal error: Uncaught exception 'Swift_TransportException'
with message 'Expected response code 250 but got code "501", with message "501 5.5.4 Invalid domain name "'

Actually I follow the tutorial straightly, so is that any thing I omitted in my code? The SMTP server information is valid.
External SMTP setting:
Server name: pod51003.outlook.com - you can also see the note below on how to determine the server name
Port: 587
Encryption method: TLS
after adding the line: there is another error:
Warning: stream_socket_enable_crypto() [streams.crypto]: this stream does not support SSL/crypto in C:\xampp\htdocs\fyp\plugin\swift\lib\classes\Swift\Transport\StreamBuffer.php on line 102

Answer 1

Try adding this line here as shown:
// Create the Transport
$transport = Swift_SmtpTransport::newInstance('pod51003.outlook.com',587,'tls')
->setUsername('user#connect.polyu.hk')
->setPassword('pw')
;
// ADD THIS LINE
$transport->setLocalDomain('[127.0.0.1]');
// Create the Mailer using your created Transport
$mailer = Swift_Mailer::newInstance($transport);
I'm guessing your SMTP server doesn't like/understand IPv6, based on the response you are getting to the HELO command.
