problem with hidden copy in phpmailer

Question

Guys I’m trying to send several emails with phpmailer, my recipients are receiving them, but to avoid them seeing to whom else I sent the emails, I used the following function:

$email->AddBCC($resultado_nome->email, $resultado_nome->nome);

The problem is that they receive the email with the following:

undisclosed-recipients:;

Good currently I pass the following way:

// Define os destinatário(s)
$consulta_nome = $mysqli->query("select * from cadastro");
while ($resultado_nome = mysqli_fetch_object($consulta_nome)) {


   // Destinatório e cópia oculta
   $email->AddBCC($resultado_nome->email, $resultado_nome->nome);

   // Iremos enviar o email no formato HTML
   $email->IsHTML(true);

   // Define a mensagem (Texto e Assunto)
   $email->Subject = "Nova email";
   $email->Body = "emai";

   // Envia o e-mail
   $email->Send();
}

Is it wrong? That way you send an email to everyone on my registration list

Someone knows how I fix it?

Answer 1

This happens because all recipients are hidden.

See the changelog v1.7 2003:

Adds "To: undisclosed-Recipients:;" when all Recipients are Hidden (BCC)

[en] Adds "To: undisclosed-Recipients:;" when all recipients are hidden (BCC)

You can see how this is handled in the source code here too:

• class.phpmailer.php#1254
• class.phpmailer.php#1946

To avoid this, you can add an email to "To" from you (e.g., [email protected]), or send one email at a time to each recipient, but that’s certainly not a 'problem'. If you choose to change, it will be by 'aesthetic' same.
