The problem with automatic creating DKIM DMARC
I think that they need to know everything and discuss it does not make sense. Indeed, the recordings are already in demand, and there is still no functionality for them. (Generation). BUT I would like to draw attention to this question from a different angle. DNS generation can be done through a wizard. And it may contain not only local opendkim but also external gmail services and many others. They provide an API, but there is no pick up of this data, and rather you will not be able to automatically. In my case, there are only 3 mailboxes from 651 sites on the server, everyone prefers to use external mail services. Consequently, even if you complete the opendkim hegeration, this will never solve the problem. My suggestion: The wizard DNS
Add a field api request in which by default will be a request to opendkim exec or curl, just a string. plus the ability to substitute these values (and there may be more than one) in the DNS record In this case, it does not require processing of the ispconfig interfaces. All logic will remain leka. And for each service, you can lay out a separate manus or search on the forum, the main thing is that it will already be technically possible to implement the request to both local and third-party servers. In the future, when the exact amount of required data, the method of obtaining them will be understood, it will be possible to make a full-fledged control, but this is quite a long time. Let's be realistic, we need the minimum possible opportunity.
