PHP mail() function not working despite confirmation [duplicate] - php

Question

This question already has answers here:
PHP mail function doesn't complete sending of e-mail
(31 answers)
Closed 5 years ago.
I have created a form that allows people to send an email from a website. The HTML code (see attached) calls a PHP script (see attached), and the email is supposed to be sent. The webpage displays the message "Email successfully sent", but I never actually received the email (it's not in spam either).
I have reached out to my hosting service (awaiting reply) to check whether PHP is supported or not. In the meantime, I would like to ensure that my code has no errors.
HTML:
<form action="message.php" method="post">
<fieldset>
<p>Name <span class="requiredAsterisk">*</span></p>
<input name="name"/>
<p>Email <span class="requiredAsterisk">*</span></p>
<input name="email"/>
<p>Message <span class="requiredAsterisk">*</span></p>
<textarea name="message"></textarea>
</fieldset>
<fieldset>
<input class="sendMessage w3-large" type="submit" value="Send Message"/>
</fieldset>
</form>
PHP:
<?php
$header = 'From: ' .$_POST['name'] ."\r\n" .'Reply-to: ' .$_POST['email'] ."\r\n" .'X-Mailer: PHP/' .phpversion();
if (mail("email#mail.com", "Email from website", $_POST['message'], $header)) {
echo ("<p>Email successfully sent</p>");
} else {
echo ("<p>Email failed</p>");
}
?>
Thanks in advance

A good alternative to the original mail() function in PHP would be something like PHPMailer. As stated in the github page:
the vast majority of code that you'll find online that uses the mail()
function directly is just plain wrong! Please don't be tempted to do
it yourself - if you don't use PHPMailer, there are many other
excellent libraries that you should look at before rolling your own -
try SwiftMailer, Zend_Mail, eZcomponents etc.
PHPMailer is super easy to set up and get going. This is the basic syntax to send an email:
<?php
require 'PHPMailerAutoload.php';
$mail = new PHPMailer;
//$mail->SMTPDebug = 3; // 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 = 'user#example.com'; // SMTP username
$mail->Password = 'secret'; // SMTP password
$mail->SMTPSecure = 'tls'; // Enable TLS encryption, `ssl` also accepted
$mail->Port = 587; // TCP port to connect to
$mail->setFrom('from#example.com', 'Mailer');
$mail->addAddress('joe#example.net'); // Add a recipient
$mail->Subject = 'Here is the subject';
$mail->Body = 'This is the HTML message body <b>in bold!</b>';
$mail->AltBody = 'This is the body in plain text for non-HTML mail clients';
if(!$mail->send()) {
echo 'Message could not be sent.';
echo 'Mailer Error: ' . $mail->ErrorInfo;
} else {
echo 'Message has been sent';
}

(I would probably comment this, but my rep is too low) You should use
$message = wordwrap($_POST['message'], 70, "\r\n"); so your message follows the documentation on mail(). Besides this, your code seems to be fine. As you mentioned, it is probably related to your hosting provider, as it is common place for them to block the mail function. Also see this question on it for some extras which may the cause of your problem.
