Swift mailer triggers fatal error;

Question

Fatal error: Uncaught exception 'Swift_TransportException' with message 'Expected response code 250 but got code "530", with message "530 5.7.0 Must issue a STARTTLS command first. fb9sm57232081wid.2 - gsmtp "' in C:\xampp\htdocs\lib\classes\Swift\Transport\AbstractSmtpTransport.php:386 Stack trace: #0 C:\xampp\htdocs\lib\classes\Swift\Transport\AbstractSmtpTransport.php(281): Swift_Transport_AbstractSmtpTransport->_assertResponseCode('530 5.7.0 Must ...', Array) #1 C:\xampp\htdocs\lib\classes\Swift\Transport\EsmtpTransport.php(245): Swift_Transport_AbstractSmtpTransport->executeCommand('MAIL FROM: executeCommand('MAIL FROM: _doMailFromCommand('sophie3394@gm...')

4 C:\xampp\htdocs\lib\classes\Swift\Transport\AbstractSmtpTransport.php(444):

Swift_Transport_AbstractSmt in C:\xampp\htdocs\lib\classes\Swift\Transport\AbstractSmtpTransport.php on line 386

This is the error caused by the following code:

ini_set("SMTP","ssl://smtp.gmail.com");
ini_set("smtp_port","465");

require_once 'lib/swift_required.php';

$transport = Swift_SmtpTransport::newInstance('smtp.gmail.com', 25)
    ->setUsername('[email protected]')
    ->setPassword('xxxx');

$mailer = Swift_Mailer::newInstance($transport);

$message = Swift_Message::newInstance('Test Subject')
    ->setFrom(array('[email protected]' => 'ABC'))
    ->setTo(array('[email protected]'))
    ->setBody('This is a test mail.');

$result = $mailer->send($message);

What are the steps to resolve this error?

Answer 1

Change the port in your code (second argument of the newInstance function) and add a third argument 'ssl'

$transport = Swift_SmtpTransport::newInstance('smtp.gmail.com', 465, 'ssl')

It was 25 and the ssl was missing. Swift_SmtpTransport was not using encryption at all and Gmail was complaining about that.
