    I deploy an Ubuntu 18.04 with ISPConfig 3.1.13p1. I also follow the step to create a DKIM for my domain. I host my domain on Linode and they also teach me how to set the record on their DNS manager. I check my every mail sent by my owner mail server turns out to be:
    DKIM no signature.

    I check them with Thunderbird v60.7 for Windows with "DKIM Verifier" addon.

    I can see emails sent from other domains carrying DKIM signatures.

    What is the reason that our DKIM does not carry a signature? How do I correct it? :(

    I think our DKIM implementation is not complete! :(

    Did you enable dkim for the email domain and created a dkim signing key in ispconfig (see dkim option in email domain settings)? Did you then set this key that you created in ISPConfig on your linode dns server?

    It suddenly works after I have corrected the postfix master conf!!!
    Thunderbird shows that my DKIM is signed!!!
