Пытаюсь отправить подписанное сертификатом письмо. Однако при отправке с добавлением строк "$mail->sign" - письмо приходит пустым. Без них же всё нормально. В чём может быть проблема?
<?php

require 'class.phpmailer.php';
//Create a new PHPMailer instance
$mail = new PHPMailer();
//Set who the message is to be sent from
//IMPORTANT: This must match the email address of your certificate.
//Although the certificate will be valid, an error will be thrown since it cannot be verified that the sender and the signer are the same person.
$mail->setFrom('from@example.com', 'First Last');
//Set an alternative reply-to address
$mail->addReplyTo('replyto@example.com', 'First Last');
//Set who the message is to be sent to
$mail->addAddress('example@mail.ru', 'John Doe');
//Set the subject line
$mail->Subject = 'PHPMailer mail() test';
//Read an HTML message body from an external file, convert referenced images to embedded,
//Convert HTML into a basic plain-text alternative body
$mail->msgHTML(file_get_contents('contents.html'), dirname(__FILE__));
//Replace the plain text body with one created manually
$mail->AltBody = 'This is a plain-text message body';
//Attach an image file
$mail->addAttachment('images/phpmailer_mini.png');
//Configure message signing (the actual signing does not occur until sending)
$mail->sign(
'qwe.crt', //The location of your certificate file
'qwe.key', //The location of your private key file
'', //The password you protected your private key with (not the Import Password! may be empty but parameter must not be omitted!)
'' //The location of your chain file
);
//Send the message, check for errors
if (!$mail->send()) {
echo "Mailer Error: " . $mail->ErrorInfo;
} else {
echo "Message sent!";

/**
* REMARKS:
* If your email client does not support S/MIME it will most likely just show an attachment smime.p7s which is the signature contained in the email.
* Other clients, such as Thunderbird support S/MIME natively and will validate the signature automatically and report the result in some way.
