I am trying to send an email through the Phpmailer library, but I was not successful :/.

Server: Hostgator

Follows code:

<?php 
$nome = $_POST["nome"];
$email = $_POST["email"];
$assunto = $_POST["assunto"];
$msg  = $_POST["msg"];

// Import PHPMailer classes into the global namespace
// These must be at the top of your script, not inside a function
use PHPMailer\PHPMailer\PHPMailer;
use PHPMailer\PHPMailer\Exception;

//Load composer's autoloader
require '../phpmailer/vendor/autoload.php';

$mail = new PHPMailer(true);                              // Passing `true` enables exceptions

try {
    //Server settings
    $mail->SMTPDebug = 2;                                 // Enable verbose debug output
    $mail->isSMTP();                                      // Set mailer to use SMTP
    $mail->Host = 'smtp.hostgator.com';  // Specify main and backup SMTP servers
    $mail->SMTPAuth = true;                               // Enable SMTP authentication
    $mail->Username = '[email protected]';                 // SMTP username
    $mail->Password = 'minhaSenha';                           // SMTP password
    $mail->SMTPSecure = 'tls';                            // Enable TLS encryption, `ssl` also accepted
    $mail->Port = 25;                                    // TCP port to connect to

    //Define o remetente
    $mail->setFrom($email, $nome);

    //Define o destinatário
    $mail->addAddress('[email protected]');     // Add a recipient

    //Content
    $mail->isHTML(true);                                  // Set email format to HTML
    $mail->Subject = $assunto;
    $mail->Body    = '<html>De: '.$nome.'<br/>Email:'.$email.'<br/>Assunto:'.$assunto.'Mensagem: '.$msg.'</html>';
    $mail->AltBody = 'This is the body in plain text for non-HTML mail clients';

    $mail->send();
    echo 'Message has been sent';
} catch (Exception $e) {
    echo 'Message could not be sent.';
    echo 'Mailer Error: ' . $mail->ErrorInfo;
}

Error message:

I was able to make it work in gmail, using the necessary settings for it and also had to enable the option in gmail "Allow less secure applications".

But I can’t send it to the hostgator’s e-mail.

Could someone help me?

OBS: We do not Authorize the use of this system to transport unsolicited, 220 and/or Bulk e-mail.

That would be a lock on their server?

Gate 25 is not a secure port, not even used in TLS:

$mail->SMTPSecure = 'tls';                            // Enable TLS encryption, `ssl` also accepted
$mail->Port = 25;                                    // TCP port to connect to

And as per this link https://supporte.hostgator.com.br/hc/pt-br/articles/115000802394-Como-usar-o-e-mail-em-plataformas-externas-#data

The correct doors are:

IMAP SSL - 993
SMTP SSL - 465

That is SMTP uses SSL and not TLS with port 465, correct:

$mail->SMTPSecure = 'ssl';
$mail->Port = 465;

I tried without tls, with tls with port 587, with port 465 + ssl and always gives the same result

@Nicolasguilhermematheus is sure it’s the same mistake, wouldn’t it be a different mistake? The log you put is on the port=25, paste the log according to the port and the correct protocol.

was going to edit the message, with ssl, the error is this one: 2018-01-12 20:52:19 SMTP ERROR: Failed to connect to server: (0) SMTP connect() failed. https://github.com/PHPMailer/PHPMailer/wiki/Troubleshooting Message could not be sent.Mailer Error: SMTP connect() failed. https://github.com/PHPMailer/PHPMailer/wiki/Troubleshooting

@Nicolasguilhermematheus first changes the $mail->SMTPDebug = 2; for $mail->SMTPDebug = 3;, forehead and take the log and then edit the question and paste the log there in the question.

@Nicolasguilhermematheus what is your email domain? I believe smtp.hostgator.com is incorrect.

@Nicolasguilhermematheus for nothing, may have been a cache or other fault, how good that this solved, until more.
