Problem sending email via PHP. Hidden copy is not coming

Question

I have a PHP file on a website that receives via POST the return sent by Pagseguro on purchases made on the site -- client name, amount paid, e-mail... finally, all the information regarding the purchase.

In this file I have a script that sends to the customer’s email a message about the purchase, using the data sent by Pagseguro.

In this script I have a line where I get a hidden copy of the message:

$headers .= "Bcc: [email protected]\r\n";

I always got the message, but I noticed that, for a few days now, I haven’t received anything, and I even thought that no sale was being made, but the sales are taking place normally.

The code is this:

$headers = "MIME-Version: 1.1\r\n";
$headers .= "Content-type: text/html; charset=iso-8859-1\r\n";
$headers .= "From: [email protected]\r\n"; // remetente
$headers .= "Bcc: [email protected]\r\n";
$headers .= "Return-Path: [email protected]\r\n"; // return-path
mail($CliEmail, "Cupom Ticiana Werner Restaurante - ".$codCupom, $corpo, $headers);

All variables are correct. I have already done a test changing the $CliEmail by my email "[email protected]" and the message usually arrives in my mailbox, IE, no mistake happens.

The problem seems to be on the line that sends the hidden copy as I get nothing:

$headers .= "Bcc: [email protected]\r\n";

Any idea what it might be? Because I always received this hidden copy before and now nothing.

UPDATING:

I changed the "Bcc" to "Cc" and received the copy normally! The problem is the "Bcc" that no longer works.

The Gmail probably thinking it’s SPAM, and it won’t get in the Inbox, maybe even the SPAM box will arrive (check this first), recommend you try sending via SMTP.

There is a library called phpmailer, install via Composer:

composer require phpmailer/phpmailer

And use it like this:

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

//Load composer's autoloader
require 'vendor/autoload.php';

If you don’t have Composer you can download via release and add by url https://github.com/PHPMailer/PHPMailer/releases (the last of preference) and so add:

<?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';

To send do this:

$mail = new PHPMailer(true);

try {
    //Server settings
    $mail->SMTPDebug = 2; //Ativa o DEBUG, desative quando mandar pro servidor de produção
    $mail->isSMTP();
    $mail->Host = 'smtp.doseuservidor.com';
    $mail->SMTPAuth = true;
    $mail->Username = '[email protected]';                 // SMTP username
    $mail->Password = 'SENHA';                           // SMTP password
    $mail->SMTPSecure = 'tls';                            // Se o seu servidor usar TLS, troque por ssl se necessário, ou remova se não tiver nenhum dos dois
    $mail->Port = 587;                                    // troque pela porta para SSL ou TLS ou sem

    $mail->setFrom('[email protected]');
    $mail->addAddress($CliEmail);
    $mail->addBCC('[email protected]');

    $mail->isHTML(true); //Formato HTML
    $mail->Subject = 'Cupom Ticiana Werner Restaurante - '.$codCupom;
    $mail->Body    = $body;
    $mail->AltBody = strip_tags($body);//Alternative em Texto

    $mail->send(); //Envia

    echo 'Email enviado';
} catch (Exception $e) {
    echo 'Erro: ' . $mail->ErrorInfo;
}
