In the example on the page https://github.com/PHPMailer/PHPMailer at the very bottom of the block with e-mail addresses there are 2 addresses: addCC and addBCC - what are they for?
//Recipients $mail->setFrom('from@example.com', 'Mailer'); $mail->addAddress('joe@example.net', 'Joe User'); // Add a recipient $mail->addAddress('ellen@example.com'); // Name is optional $mail->addReplyTo('info@example.com', 'Information'); $mail->addCC('cc@example.com'); $mail->addBCC('bcc@example.com');
