Ошибка сервера номер 500 phpmailer

I’m trying to send an email using the following code and I’m getting Internal Server Error. I am not sure why I am having this trouble.

PHP code:

<?php
    $mail = new PHPMailer();  // create a new object
    $mail->IsSMTP(); // enable SMTP
    $mail->SMTPDebug = 0;  // debugging: 1 = errors and messages, 2 = messages only
    $mail->SMTPAuth = true;  // authentication enabled
    $mail->SMTPSecure = 'ssl'; // secure transfer enabled REQUIRED for Gmail
    $mail->Host = 'smtp.gmail.com';
    $mail->Port = 465; 
    $mail->Username = 'myemail@gmail.com';  
    $mail->Password = "mypasswordhere";           
    $mail->SetFrom($from, $from_name);
    $mail->Subject = $subject;
    $mail->Body = $body;
    $mail->AddAddress('myemail@gmail.com');
    if(!$mail->Send()) {
        $error = 'Mail error: '.$mail->ErrorInfo; 
        return false;
    } else {
        $error = 'Message sent!';
        return true;
    }
?>

I just placed this file as test.php inside the PhpMail folder after extracting it. Like the below

Пытаюсь отправить письмо через smtp Яндекса. При отправке формы получаю ошибку «send.php Status Code: 500 Internal Server Error»

Что сделал:
1. Изменил MX-запись. В настройках домена в сервисе connect.yandex.ru написано «Домен подтверждён и готов к работе»
2. Залил PHPMailer на хостинг. Три файла в папку /PHPMailer/PHPMailer/ (Exception.php, PHPMailer.php, SMTP.php) и send.php с моими настройками в корень сайта.

Кусочек send.php:

$mail->Host       = 'smtp.yandex.com';  // Specify main and backup SMTP servers
    $mail->SMTPAuth   = true;                                   // Enable SMTP authentication
    $mail->Username   = 'mail@mydomain.ru';                     // SMTP username
    $mail->Password   = 'password';                               // SMTP password
    $mail->SMTPSecure = 'ssl';                                  // Enable TLS encryption, `ssl` also accepted
    $mail->Port       = 465;

В строчке «$mail->Password» использую пароль для приложения, который выдается в настройках почты в Яндексе.

Что может быть не так?

yes I have commented that line and the error still exist, composer validate gives the following output:

Solution 1

Looks like you’re dealing with bunch of issues and here is a checklist: you’re having issues with ssl, the actual mail software and credentials. It became an issue of 3 from one main issue and I’m guessing you don’t either have your credentials typed in correctly or your open ssl isn’t setup and you’re also having issues using the mail software.

535 535 5.7.3 Authentication Unsuccessful means auth is unsuccessful, check your credentials username and password.

550 error code, it means that the receiving system could not deliver your email to the user to whom it was addressed because the mailbox is unavailable.

There are plenty of other solutions to resolve your issue. Why don’t you try something more simple instead of using the autoload PHPMailerAutoload.php. Create a new file and place the code below, create a message body (test_message.html) and call it from the browser to test gmail smtp with the gmail credentials. This is a snippet from PHPMailer on how to use it with gmail smtp and it shouldn’t go wrong if you have everything filled in correctly.

<?php
    require_once('../class.phpmailer.php');
    //include("class.smtp.php"); // optional, gets called from within class.phpmailer.php if not already loaded

    $mail             = new PHPMailer();

    $body             = file_get_contents('test_message.html');
    $body             = eregi_replace("[]",'',$body);

    $mail->IsSMTP(); // telling the class to use SMTP
    $mail->Host       = "mail.yourdomain.com"; // SMTP server
    $mail->SMTPDebug  = 2;                     // enables SMTP debug information (for testing)
                                               // 1 = errors and messages
                                               // 2 = messages only
    $mail->SMTPAuth   = true;                  // enable SMTP authentication
    $mail->SMTPSecure = "tls";                 // sets the prefix to the servier
    $mail->Host       = "smtp.gmail.com";      // sets GMAIL as the SMTP server
    $mail->Port       = 587;                   // set the SMTP port for the GMAIL server
    $mail->Username   = "[email protected]";  // GMAIL username
    $mail->Password   = "yourpassword";            // GMAIL password

    $mail->SetFrom('nam[email protected]', 'First Last');

    $mail->AddReplyTo("[email protected]","First Last");

    $mail->Subject    = "PHPMailer Test Subject via smtp (Gmail), basic";

    $mail->AltBody    = "To view the message, please use an HTML compatible email viewer!"; // optional, comment out and test

    $mail->MsgHTML($body);

    $address = "[email protected]";
    $mail->AddAddress($address, "John Doe");

    $mail->AddAttachment("images/phpmailer.gif");      // attachment
    $mail->AddAttachment("images/phpmailer_mini.gif"); // attachment

    if(!$mail->Send()) {
      echo "Mailer Error: " . $mail->ErrorInfo;
    } else {
      echo "Message sent!";
    }
    ?>

If you’re getting user auth error, then your credentials aren’t typed in
correctly. If that’s not the issue, you’ll get an ssl error if you’re not using the right port.

If there are software issues with include, you should try something better.

I was debating this morning if I should should PHPMailer, ended up using Swiftmailer which worked right after I installed it with PHPComposer.

My Internal mail server is extremely picky and has ton of firewall settings and rules on hardware and software level and I was surprised it didn’t give me any problems; the emails were being sent right away without any problems on port 587.

require_once 'vendor/swiftmailer/swiftmailer/lib/swift_required.php';
$transport = Swift_SmtpTransport::newInstance('mail.hellog***.com', 587)
  ->setUsername('[email protected]***.com')
  ->setPassword('apa******')
  ;

This is what you need for gmail:

$transporter = Swift_SmtpTransport::newInstance('smtp.gmail.com', 465, 'ssl')
  ->setUsername($this->username)
  ->setPassword($this->password);

$this->mailer = Swift_Mailer::newInstance($transporter);

If none of what you like, you can try phpgmailer:
https://github.com/GregDracoulis/LectureBank/tree/master/phpgmailer

here is an example on how to use it:
http://www.vulgarisoverip.com/2006/10/13/update-send-email-with-php-and-gmail-hosted-for-your-domain/

this class is dedicated for gmail use.

If all your problems and issues relate to openSSL, you should follow the steps below:

1. Make sure the OpenSSL module DLL file is included in the PHP installation:

C:user>dir localphpextphp_openssl.dll

Directory of C:localphpext

php_openssl.dll

2. Create the PHP configuration file, localphpphp.ini, if it does not exist:

C:user>copy localphpphp.ini-production localphpphp.ini

    1 file(s) copied.

3. Enable the OpenSSL module by editing the configuration file with a text editor. You need to remove the comment maker (;) on two configuration lines:

...

; Directory in which the loadable extensions (modules) reside.
; http://php.net/extension-dir
; extension_dir = "./"
; On windows:
extension_dir = "ext"

...
extension=php_openssl.dll

...

That’s it. You should be all set setting up openSSL on your Windows IIS WebServer. Follow these options and steps, it could be your issue.

Solution 2

I have tried with you code, and i have only changed this line :

require_once ("inclPHPMailerPHPMailerAutoload.php");

by this one :

require_once ("inclPHPMailerclass.phpmailer.php");

And it was worked successfully.
Also you should keep attention about your PHPMailer version and your PHP version.
Have you tried to send an email with not secured method ?
Are you sure that your google credentials are valid ?

UPDATED
From the command line of your server, what is the output of this command and how much time that it takes to respond

telnet smtp.gmail.com 587

Solution 3

This problem is slashes ( )

Edit

require_once ("incl\PHPMailer\PHPMailerAutoload.php");
