PHPmailer not working recipient - php

Question

I have a problem, with my code beneath I get this error message:
Message could not be sent.Mailer Error: SMTP Error: The following recipients failed: !Censored!
I have looked into the Host, Port, Username, Password, Recipient and all is correct, what is the problem? Thank you!
Could you please explain too cuz Im new to PHP-coding
<?php
require 'PHPMailerAutoload.php';
$mail = new PHPMailer;
$name = $_POST['name'];
$email = $_POST['email'];
$subject = $_POST['amne'];
$message = $_POST['message'];
//$mail->SMTPDebug = 3; // Enable verbose debug output
$mail->isSMTP(); // Set mailer to use SMTP
$mail->Host = '!Censored!'; // Specify main and backup SMTP servers
$mail->SMTPAuth = true; // Enable SMTP authentication
$mail->Username = '!Censored!'; // SMTP username
$mail->Password = '!Censored!'; // SMTP password
$mail->SMTPSecure = 'tls'; // Enable TLS encryption, `ssl` also accepted
$mail->Port = 587; // TCP port to connect to
$mail->From = $email;
$mail->FromName = $name;
$mail->addAddress('!Censored!'); // Add a recipient
$mail->addAttachment('/var/tmp/file.tar.gz'); // Add attachments
$mail->addAttachment('/tmp/image.jpg', 'new.jpg'); // Optional name
$mail->isHTML(true); // Set email format to HTML
$mail->Subject = $subject;
$mail->Body = $message;
$mail->AltBody = $message;
if(!$mail->send()) {
echo 'Message could not be sent.';
echo 'Mailer Error: ' . $mail->ErrorInfo;
} else {
echo 'Message has been sent';
}
EDIT: I found the problem, the problem was not in the php code itself. It was in the contact form. The problem started when I put the variables as names and emails. If the email is not verified, it does not work.

This error can be caused by a few different things. You can get a better idea of the reason by adding the following line to your PHPMailer script:
$mail->SMTPDebug = 2; //<-- For debugging
Once you do that, you can check the following things that may be causing the error:
1.) A corrupt class.phpmailer.php file.
2.) The error may be caused by protection put in place by your ISP. Check with them.
3.) It could be a problem with the recipient's/sender's email addresses.
4.) Set SMTPAuth to true for PHPMailer class.
5.) Comment out the following line in your PHPMailer script: $mail->isSMTP();
Mostly, There is possibility that Your phpmailer class file is corrupted.
