Problem sending email via PHP. Blind copy is not coming


I have a PHP file on a site that receives via POST the return sent by PagSeguro about purchases made on the site – customer name , amount paid , e-mail … in short, all the information regarding the purchase.

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

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

$headers .= "Bcc:\r\n";

I always received the message, but I noticed that, for a few days now, I have not received anything, and I even thought that no sales were being made, but 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:\r\n"; // remetente
$headers .= "Bcc:\r\n";
$headers .= "Return-Path:\r\n"; // return-path
mail($CliEmail, "Cupom Ticiana Werner Restaurante - ".$codCupom, $corpo, $headers);

All variables are correct. I've already done a test by exchanging $CliEmail for my email "" and the message normally arrives in my mailbox, that is, no error happens.

The problem seems to be in the line that sends the blind copy, as I don't get anything:

$headers .= "Bcc:\r\n";

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


I changed the "Bcc" to "Cc" and received the copy normally! The problem is the "Bcc" that doesn't work anymore.


Gmail is probably thinking it's SPAM, and it won't arrive in the inbox, maybe not even the SPAM inbox (check this first), I recommend you try sending via SMTP.

There is a library called phpmailer , install via composer:

composer require phpmailer/phpmailer

And use it like this:

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 via url (the last preference) and add it like this:

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->Host = '';
    $mail->SMTPAuth = true;
    $mail->Username = '';                 // 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->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;
