for gmail OJS 3.0.0-8 unable to send

We use gmail for enterprise. Our email addresses are still all like ‘’:
This is what I used to successfully test sending an email through PHPMailer. It works, so the password is correct, and the account has been set to allow for 3rd party applications.
This is the phpmailer code and it works:

$mail = new PHPMailer(true);
try {
// Server settings
//$mail->SMTPDebug = SMTP::DEBUG_SERVER; // for detailed debug output
$mail->Host = ‘’;
$mail->SMTPAuth = true;
$mail->Port = 587;

$mail->Username = ''; // YOUR gmail email
$mail->Password = 'totallyrealpassword'; // YOUR gmail password

// Sender and recipient settings
$mail->setFrom('', 'Sender Name');
$mail->addAddress('', 'Receiver Name');
$mail->addReplyTo('', 'Sender Name'); // to set the reply to

// Setting the email content
$mail->Subject = "Let the email soar";
$mail->Body = 'HTML message body. <b>Gmail</b> SMTP email body.';
$mail->AltBody = 'Plain text message body for non-HTML email client. Gmail SMTP email body.';

echo "Email message sent.";

} catch (Exception $e) {
echo “Error in sending email. Mailer Error: {$mail->ErrorInfo}”;

This is what I have for and it doesn’t work (obviously I’m missing something):

The error message given is a vague “Connection failed” followed by a link to PHPMailer’s github.
