    It looks like the SMTP.php file is working pretty nice.

    This heavy bug is still not fixed and can cause a lot of trouble if using your own mailserver,

     

    Just one bug in the SMTP.php file i found, you forget to add the subject into the fputs.

    Fix:

    adding after: fputs($smtp_conn,"DATA\r\n");

    This lines:

    fputs($smtp_conn,"Subject: $YOURSUBJECT\r\n");
    $data = get_data($smtp_conn);

    Hello Daniel,

    Thank you for your notice. SMTP.php has been updated with Subject line.

    The same happens with emails that are being sent from the server when auto-reply is enabled in an email account. The email is being sent but not signed with DKIM. I just test it with Plesk Onyx Version 17.8.11 Update #38 on CentOS 6.10.

    Do you think it is the same issue or should i post it on a new thread?
