[resolved] Cannot send emails due to duplicate header (3 posts)

    PHPMailer (part of WordPress) unconditionally adds the "MIME-Version" header to outgoing email messages. This causes MTAs like Postfix and Exim to reject the emails due to duplicate headers.

    There are two places in subscribe-to-comments-reloaded.php where I applied a simple patch:

    // PhpMailer adds this header without checking if it already exists
    // $headers = "MIME-Version: 1.0\n";
    $headers = "From: $from_name <$from_email>\n";

    I found a couple more places that need to have a similar modification made:

    templates/request-management-link.php
    templates/subscribe.php
