php mail() fails on ubuntu server

I'm trying to write a code to send emails from a contact form, I'm doing tests on a ubuntu server and here is the php config on this server:

enter image description here

And here is my php code (I've tested this same code in other online production server and works perfectly):

<?php 
$ToEmail = '[email protected]'; 
$EmailSubject = 'Site contact form'; 
$mailheader = "From: ".$_POST["email"]."\r\n"; 
$mailheader .= "Reply-To: ".$_POST["email"]."\r\n"; 
$mailheader .= "Content-type: text/html; charset=iso-8859-1\r\n"; 
$MESSAGE_BODY = "Name: ".$_POST["name"].""; 
$MESSAGE_BODY .= "Email: ".$_POST["email"].""; 
$MESSAGE_BODY .= "Comment: ".nl2br($_POST["comment"]).""; 
mail($ToEmail, $EmailSubject, $MESSAGE_BODY, $mailheader) or die ("Failure"); ?>

This code isn't working on my Ubuntu server, what can I do? I don't want to use libraries. I read that in Linux server there is no need to install anything and no need to add a SMTP configuration on the code, even in the php manual give some basics examples to send emails and those don't have any SMTP code. What is the problem with this code?

Solution

  • This isn't the answer you wanted but probably the best way to tackle given our discussion on the main question.

    A PHPMailer Example

    You'll just need to adapt your current code to your variables listed in your original code.

    Source: PHPMailer Example - Official Package GitHub

    <?php
// 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 '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 = 'smtp1.example.com;smtp2.example.com';  // Specify main and backup SMTP servers
    $mail->SMTPAuth = true;                               // Enable SMTP authentication
    $mail->Username = '[email protected]';                 // SMTP username
    $mail->Password = 'secret';                           // SMTP password
    $mail->SMTPSecure = 'tls';                            // Enable TLS encryption, `ssl` also accepted
    $mail->Port = 587;                                    // TCP port to connect to

    //Recipients
    $mail->setFrom('[email protected]', 'Mailer');
    $mail->addAddress('[email protected]', 'Joe User');     // Add a recipient
    $mail->addAddress('[email protected]');               // Name is optional
    $mail->addReplyTo('[email protected]', 'Information');
    $mail->addCC('[email protected]');
    $mail->addBCC('[email protected]');

    //Attachments
    $mail->addAttachment('/var/tmp/file.tar.gz');         // Add attachments
    $mail->addAttachment('/tmp/image.jpg', 'new.jpg');    // Optional name

    //Content
    $mail->isHTML(true);                                  // Set email format to HTML
    $mail->Subject = 'Here is the subject';
    $mail->Body    = 'This is the HTML message body <b>in bold!</b>';
    $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. Mailer Error: ', $mail->ErrorInfo;
}
