    On Centos 7.3, ispconfig-3 3.1.3, I am setting up DKIM for a domain. On the first attempt it broke amavisd on a path error. I ran ln -s /etc/amavisd/amavisd.conf /etc/amavisd.conf, created /var/lib/amavis/dkim and chowned it to amavisd.amavisd. amavisd restarted.

    I recreated the DKIM keys for the domain and it created the key pair in /var/lib/amavis/dkim and put the record in the DNS for the domain. However, when I run amavisd showkeys, it only shows the private key and when I run amavisd testkeys it errors out saying that the public key is not available:

    TESTING#1 => invalid (public key: not available)

    I tried recreating the keys a few times but the problem remains. Any thoughts / help appreciated so much.

    If you use an external dns, it seems, that you missed some settings or the dns does not support longer txt-records. You can use amavisd-new showkeys to see the correct public key.

    Thank you Florian, The problem was the DNS setup.
