Hi, I have ISP Config 3.1.3 and have enabled DKIM signing on one of my domains. However when I am sending emails they are not being signed. I do not know where to start with working out why not, any help appreciated.
Did you created dkim-keys for the mail-domains? You can debug the dkim-setup: https://blog.schaal-24.de/dkim/debug-2/?lang=en
