PHPMailer SMTP Connection Failed with Gmail o Domain - GoDaddy - php

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();
