Unable to send mail with PHPMailer and Mailtrap

Question

I am trying to send a test e-mail to a mailtrap.io inbox, but I keep getting these errors when I turn the debugging on. Previously I was getting a Username command failed until I added AuthType = Login.

Here is my code on the page that tries to send the e-mail. The credentials are stored in the Config class, and I have verified several times that the username and password match the ones provided by the mailtrap inbox. Currently the port is set to 465. I have tried 2525 as well to the same results. Port 25 only makes the application time out.

if(isMethod('post')) {
    if (isset($_POST['email'])) {
        /*********************
         *configure PHPMailer*
         *********************/
        $mail = new PHPMailer();
        $mail->AuthType = 'LOGIN';
        $mail->SMTPDebug = 2;
        $mail->isSMTP();
        $mail->Host = Config::SMTP_HOST;
        $mail->SMTPAuth = true;
        $mail->Username = Config::SMTP_USER;
        $mail->Passowrd = Config::SMTP_PASSWORD;
        $mail->SMTPSecure = 'tls';
        $mail->Port = Config::SMTP_PORT;
        $mail->isHTML(true);
        $mail->setFrom('myemail@gmail.com', 'My Name');
        if (!getEmailDb()) {
            echo (displayMessage("E-Mail does not exist.", "warning"));
        }
        else {
            $email = getEmailDb();
            $token = bin2hex(openssl_random_pseudo_bytes(50));
            $mail->addAddress($email);
            $mail->Subject = 'This is a test email.';
            $mail->Body = 'Email body';

            if($mail->send()) {
                echo (displayMessage("E-Mail sent. It should show up in your inbox pretty soon.", "success"));
            }
            else {
                echo (displayMessage("Could not send E-Mail to ".$email, "warning"));
            }
        }
    }

}

Set `$mail->SMTPDebug = 2;` so you can see what the server is saying. TLS won't work to port 465; try 587. Also, read the troubleshooting guide the error message points you at. — Synchro, Aug 01 '17 at 22:24
Using that port gives a timeout. Mailtrap says to use 25, 465 or 2525 for SMTP connections. I will edit this post with debugging level 2 information under port 465. — SolidSnackDrive, Aug 01 '17 at 22:34
Maybe [this](https://stackoverflow.com/a/25670661/2917673) could help — Yolo, Aug 01 '17 at 22:57
In that case set `SMTPSecure = 'ssl'` with `Port = 465`, though note that this is exceedingly unlikely to work correctly when `Host = 'localhost'`. All of this is covered in the guide. — Synchro, Aug 01 '17 at 23:12
You will like to check this https://github.com/PHPMailer/PHPMailer/wiki/Troubleshooting This issue and similar ones were addressed. — Oluwatobi Samuel Omisakin, Aug 02 '17 at 00:05
I have read the troubleshooting guide, thank you, but as I have already specified I am NOT using GMail or Google Apps. I am using mailtrap. — SolidSnackDrive, Aug 02 '17 at 19:30

Found out the issue. You can't just send mail from localhost without any kind of SMTP server set up, that's why I was getting errors. For anyone that comes across this in the future, Papercut for Windows can be used to test mail sending on your local machine.

This is what worked for me:

Disable SMTPSecure

$mail->SMTPSecure = false;

And change the SMTP Port to 2525

$mail->Port = 2525;
