Gmail o域的PHPMailer SMTP连接失败-GoDaddy

Question

I am working on a website with a form that is used to send email with PHPMailer. i have a GoDaddy hosting plan linux. I have tried multiple ways without any success, some time ago it worked and now does not work.

Configuration 1 with Gmail

include_once('phpmailer/class.phpmailer.php');
include_once('phpmailer/class.smtp.php');



$mail = new PHPMailer();
$mail->IsSMTP();
$mail->SMTPAuth = false;
$mail->SMTPSecure = false; (I've tried the 2 options)
$mail->Host = "relay-hosting.secureserver.net";
$mail->Port = 25;
$mail->Username ='xxxx@gmail.com';
$mail->Password = 'xxxxxxx';
$mail->Subject = 'Form from website'; 

$mail->AddAddress("xxxxx@xxxx.com");
$mail->FromName   = "formsite"; 
$mail->SMTPDebug = 3;
$mail->Debugoutput = 'html';

Log

Connection: opening to relay-hosting.secureserver.net:25, timeout=300, options=array ()

SMTP ERROR: Failed to connect to server: Connection refused (111) SMTP connect() failed. https://github.com/PHPMailer/PHPMailer/wiki/Troubleshooting

Configuration 2 email from the same domain

$mail = new PHPMailer();
$mail->IsSMTP();
    $mail->SMTPSecure = true; // Enable TLS encryption, `ssl` also accepted
    $mail->SMTPAuth = false;  // Enable SMTP authentication
     $mail->SMTPOptions = array(
    'ssl' => array(
        'verify_peer' => false,
        'verify_peer_name' => false,
        'allow_self_signed' => true
    )
);
$mail->Host = 'p3plcpnxxx.prod.phx3.secureserver.net';
$mail->Port = 465;
$mail->Username ='noreply@samedomain.com';
$mail->Password = 'xxxxxxxx'; 
$mail->Subject = 'Form from website';
$mail->AddAddress("xxxxx@xxxx.com");
$mail->FromName   = "formsite";
$mail->SMTPDebug = 3;
$mail->Debugoutput = 'html';

Answer 1

To help others struggling with GoDaddy, these two variations worked for me:

Hosting: GoDaddy shared/cPanel

Sending "From:" a GMail address

PHPMailer version 6.0.5

  $mail = new PHPMailer;
  $mail->isSMTP();

  $mail->SMTPDebug = 2;

  $send_using_config = 1; // set to 1, 2, etc. to test different settings
  switch ($send_using_config):
    case 1:
      $mail->Host = 'localhost';
      $mail->Port = 25;
      $mail->SMTPSecure = FALSE;
      $mail->SMTPAuth = FALSE;
      $mail->SMTPAutoTLS = FALSE;
      break;
    case 2:
      # Host amnd Port info obtained from:
      #   Godaddy > cPanel Home > Email > cPanel Email > Mail Configuration > "Secure SSL/TLS Settings" > Outgoing Server
      $mail->Host = 'a2plcpnxyzw.prod.iad2.secureserver.net';
      $mail->Port = 465;
      $mail->SMTPSecure = 'ssl';
      $mail->SMTPAuth = FALSE;
      $mail->SMTPOptions = array(
          'ssl' => array(
            'verify_peer' => FALSE,
            'verify_peer_name' => FALSE,
            'allow_self_signed' => TRUE
          )
      );
      break;
  endswitch;

  $mail->Username = 'you@gmail.com';
  $mail->Password = 'your_gmail_password';

  $mail->setFrom($from);
  $mail->addAddress($to);
  $mail->Subject = $subject;
  $mail->msgHTML($message);
  $mail->send();
