Im trying to write a script with which I can BCC email a large amount of people, but it's not working.

        $headers = 'From: host@host.com' . "\r\n" .
          'Bcc: user1@mail.com, user2@mail.com, user3@host.com' . "\r\n" .
          'Reply-To: host@mail.com' . "\r\n" .
          'MIME-Version: 1.0' . "\r\n" .
          'Content-type: text/html; charset=iso-8859-1' . "\r\n" .
          'X-Mailer: PHP/' . phpversion();
        mail($to, '=?UTF-8?B?'.base64_encode($subject).'?=', $message, $headers);

Whenever I run it, the script mails to only the server's owned email addresses. For example, in the above script, user3@host.com would get the email, but user1 and user2 wouldnt. Even worse, I can only actually reach user 1 or 2 by making them the $to field, but that wouldnt even work if theres still any Bcc specified.

I did not originally create this code, I'm merely trying to modify code created by the previous owner, so if I'm missing anything obvious, I'm sorry!

Thanks in advance!

    don't build mime emails yourself. it's painful, and far too easy to screw up. use PHPmailer or Swiftmailer. they both make it utterly trivial. – Marc B Mar 07 '14 at 19:34
  • If messages are not received, try using a LF (\n) only. Some Unix mail transfer agents (most notably » qmail) replace LF by CRLF automatically (which leads to doubling CR if CRLF is used). This should be a last resort, as it does not comply with RFC. – viljun Mar 07 '14 at 20:39
  • It is worth noting that the mail() function is not suitable for larger volumes of email in a loop. This function opens and closes an SMTP socket for each email, which is not very efficient. For the sending of large amounts of email, see the » PEAR::Mail, and » PEAR::Mail_Queue packages. – viljun Mar 07 '14 at 20:39
