Hi, i have install a new server with Debian Buster. I used https://www.howtoforge.com/perfect-server-debian-10-buster-apache-bind-dovecot-ispconfig-3-1/ and https://www.howtoforge.com/replacing-amavisd-with-rspamd-in-ispconfig/. After this, i have configured DKIM over ISPConfig. In some testes, i can't found any DKIM header in all my sended mails. I have checked all settings, regarding this thread: https://www.howtoforge.com/community/threads/rspamd-greylist-dkim-keys-not-loaded.82823/ I don't find any issues in my logs of rspamd, mail logs or something else. Any idea, who i can search for the problem?
