Problems sending mail with mail()

Question

I am trying to send the email, however is returned the success message, but the message is not sent.

I send the data from the frontend to the backend with Angular and the data arrives straight, but I do not know what happens that does not send.

header('Access-Control-Allow-Origin: *');
header("Access-Control-Allow-Methods: GET, POST, OPTIONS, PUT, DELETE");
header("Access-Control-Allow-Headers: X-API-KEY, Origin, X-Requested-With, Content-Type, Accept, Access-Control-Request-Method");

$_POST = json_decode(file_get_contents('php://input'), true);

$name      = $_POST['name'];
$email     = $_POST['email'];
$phone     = $_POST['phone'];
$place     = $_POST['place'];
$message   = $_POST['message'];


  $destino = "[email protected]";

  $assunto = "Cliente.";

  $headers  = 'MIME-Version: 1.0' . "\r\n";
      $headers .= 'Content-type: text/html; charset=iso-8859-1' . "\r\n";
      $headers .= 'From: $name <$email> '. "\r\n";
      $headers .= 'Telefone: $phone '. "\r\n";
  //....

  $enviaremail = mail($destino, $assunto, $headers);

  if($enviaremail)
  {
  echo 1;
  } 
  else 
  {
  echo 0;
  }

Accommodation is the Hostinger. I don’t know if it has anything to do with.

I believe it’s the fact that you’re skipping a parameter:

bool mail ( string $to , string $Subject , string $message [, string $additional_headers [, string $additional_parameters ]] )

Check out the PHP Manual.

I use the code as follows (without those headers you use, try removing them):

$name      = $_POST['name'];
$email     = $_POST['email']; 
$phone     = $_POST['phone'];
$place     = $_POST['place'];
$message   = $_POST['message'];

$m['subject'] = 'Qualquer Assunto'; 
$m['to'] = '[email protected]';

$m['message'] = '
E mail de contato:<br /><br />

Nome: '.$name.'<br />
E-mail: '.$email.'<br />
Telefone: '.$phone.'<br />
Localização: '.$place.'<br />
Mensagem: '.$message.'<br />

';

$m['headers'] = implode("\r\n",array(
                        'From: Contato <[email protected]>',
                        'Reply-To: Contato <[email protected]>',
                        'Subject: '.$m['subject'],
                        'Mime-Version: 1.0',
                        'Content-Type: text/html; charset=iso-8859-1',
                        'Priority: normal',
                        'X-Mailer: PHP/'.phpversion(),
                        'X-Priority: 3'));;

if(mail($m['to'],$m['subject'],$m['message'],$m['headers'])){   
    echo 'Seu contato foi enviado com sucesso.'; 
}
else echo 'Seu contato falhou.';

One detail is that the function mail() returns a boolean for the execution of the function so to speak, and not if the email was actually sent. The function was executed correctly, so it comes true.

Who actually sends the email is not PHP but some other software installed on the server, so PHP is not responsible for informing if the email actually left your server (sent).

Until why email in most cases ends up going to a queue, which makes your email not be sent immediately, but it will be in the near future if you think about it the return would be false which would lead to various complications.

In some accommodations the header from has to be a valid and existing email from your domain, otherwise do not send the email, then add the reply-to to the email that was on from. Something like that.

$headers  = 'MIME-Version: 1.0' . "\r\n";
$headers .= 'Content-type: text/html; charset=iso-8859-1' . "\r\n";
$headers .= 'Reply-to: $name <$email> '. "\r\n";
$headers .= 'From: [email protected] '. "\r\n";
$headers .= 'Telefone: $phone '. "\r\n";
