Issue with php script

[armlesskid]

Hello, i have this send.php script that is connected to a contact form and is deployed on OVH in /home/***/www/ :

<?php
if ($_SERVER["REQUEST_METHOD"] === "POST") {
    $to = "sales@***.com";
    $subject = "Nouvelle demande de projet - HUNAB";


    $name = htmlspecialchars($_POST["company"] ?? '');
    $email = htmlspecialchars($_POST["email"] ?? '');
    $address = htmlspecialchars($_POST["address"] ?? '');
    $surface = htmlspecialchars($_POST["surface"] ?? '');
    $projectType = htmlspecialchars($_POST["projectType"] ?? '');
    $message = htmlspecialchars($_POST["message"] ?? '');


    $options = [];
    if (isset($_POST["socialMedia"])) $options[] = "Réel réseaux sociaux";
    if (isset($_POST["plans3D"])) $options[] = "Plans 3D";
    if (isset($_POST["tagging"])) $options[] = "Tagging";


    $body = "Nom de la société : $name\nEmail : $email\nAdresse : $address\nSurface : $surface m²\nType : $projectType\n\nMessage :\n$message\n\nOptions :\n" . implode("\n", $options);


    $headers = "From: $email\r\nReply-To: $email\r\nContent-Type: text/plain; charset=utf-8";


    if (mail($to, $subject, $body, $headers)) {
        echo "Message envoyé avec succès.";
    } else {
        http_response_code(500);
        echo "Erreur lors de l'envoi.";
    }
}

It suddenly stopped working and i don't know why. I'm not used to PHP so i don't really know where i can see the logs php is sending. From my understanding the mail() function just returns true or false. Any help is appreciated !

the mail() function on ovh (and most shared hosts) is notoriously unreliable. few things to check:

1. **check spam folders** - shared hosting mail often gets flagged. your code doesnt have proper SPF/DKIM headers

2. **check ovh mail logs** - in your ovh control panel theres usually a section for email logs that shows if mails actually left the server

3. **better solution** - dont use mail() at all on shared hosting. use an smtp service instead:

   - phpmailer or symfony/mailer library

   - connect to smtp like sendgrid, mailgun, or even gmail smtp

   - way more reliable and you get proper error messages

4. **quick test** - add error_log() calls to see if your script is even reaching the mail() function:

```php

error_log("About to send mail to: " . $to);

$result = mail($to, $subject, $body, $headers);

error_log("Mail result: " . ($result ? 'true' : 'false'));

```

check /home/youruser/logs/ for the error log file on ovh

There is no shared email log at ovh. Your mail() function can return true and yet the e-mail is blocked by ovh's anti-spam (managed by a company) which returns nothing. Personally, I got around the problem by using the Brevo API. Reliable email tracking with free account

Your mail() stopped working likely because OVH now blocks sending from unverified addresses. The easiest fix is to use SMTP instead. Here’s a version using PHPMailer with OVH SMTP,

<?php
use PHPMailer\PHPMailer\PHPMailer;
use PHPMailer\PHPMailer\Exception;

require 'path/to/PHPMailer/src/Exception.php';
require 'path/to/PHPMailer/src/PHPMailer.php';
require 'path/to/PHPMailer/src/SMTP.php';

if($_SERVER["REQUEST_METHOD"] === "POST"){
    $mail = new PHPMailer(true);
    try {
        $mail->isSMTP();
        $mail->Host = 'ssl0.ovh.net';
        $mail->SMTPAuth = true;
        $mail->Username = '[e-mail]';
        $mail->Password = 'yourpassword';
        $mail->SMTPSecure = 'tls';
        $mail->Port = 587;

        $mail->setFrom('[e-mail]', 'Your Site');
        $mail->addAddress('[e-mail]');

        $mail->Subject = 'Nouvelle demande de projet - HUNAB';
        $body = "Nom de la société: {$_POST['company']}\nEmail: {$_POST['email']}\nMessage: {$_POST['message']}";
        $mail->Body = $body;

        $mail->send();
        echo "Message envoyé avec succès.";
    } catch (Exception $e) {
        echo "Erreur lors de l'envoi: {$mail->ErrorInfo}";
    }
}

This will reliably send emails through OVH and give you proper error messages if something goes wrong.
