    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?

    @Ivan 

    This is a huge bug, i mentioned a few times at the forum already and talked with developers on your help center months ago.

    It really deserves a LOT more attention.

     

    Your unable to use your own mailserver over PLESK for sending newsletter/order mails or even simple mails.

    Some mailservers block not dkim signed messages or mark them as spam. For sure you wont have success like that if you dont implement a workaround.

    Then just tell us: why so long? It's such a basic feature with big consequences.

    Hello @Daniel and @Koert!

    Thank you both for the feedback. Indeed the functionality is useful and vital for you.

    Currently, the Development Team is concentrated on other functionality improvements and bugs. However, this issue is not abandoned and will be resolved, for now without the exact ETA.
