phpmailer添加密件抄送不起作用

Question

I am using Phpmailer to send mail. It is working perfectly except for the bcc. The Bcc recipient could not see the cc and the to. Why is this happening?

require_once("PHPMailer_v5.1/class.phpmailer.php");
            $mailer = new PHPMailer();
            $mailer->IsSMTP();

            $mailer->SMTPAuth = true;
            $mailer->SMTPSecure = "tls";

            $mailer->Host = 'smtp.gmail.com';
            $mailer->Port = 587;            

            $mailer->Username = $userid;
            $mailer->Password = $epwd;
            $mailer->FromName = $fromname;
            $mailer->From = $userid;
            $mailer->AddAddress($to,$toname);
            $mailer->Subject = $subject;                
            $mailer->Body =$content;                
            $mailer->AddCC($cc, $tocc);             
            $mailer->AddBCC($bcc, $tobcc);          
            $mailer->AddAttachment($dest_filename);
            $mailer->Send()

Answer 1

There is a good chance this is a gmail issue. Did you test with another SMTP service provider?

Answer 2

From class.phpmailer.php:

/**
  * Adds a "Bcc" address. Note: this function works<br>
  * with the SMTP mailer on win32, not with the "mail"<br>
  ...
 */
function AddBCC($address, $name = '') {
  ...
}
