Document DO policy regarding email servers
DO currently has a page called https://www.digitalocean.com/community/tutorials/why-you-may-not-want-to-run-your-own-mail-server However nowhere in the doc does it call out the fact that, if you do it anyway, you will receieve no support from DO when the entire DO network IP ranges are blocked or DO ASN is blacklisted. Currently the page only talks about the difficulties of running a mail server which any mail admin already knows about. It is not explicit on DO's own policies that impact anyone running a mail server on DO. Even if a customer's email server is clean and not sending the mere fact you are running on DO can get you blacklisted and DO will not do anything to resolve the issue at their level.
More in-depth docs.
Docs should contain more-in depth sections. Generally I really like you docs, because they are concise and easy to read, so I don't want you to mess current docs with too much details which only small percentage of potential users will need, but some ADDITIONAL section with very low level details for each service would be very useful. I'm using DO for about half a year now and I has to ask Support about details a few times, I don't remember all my questions but I had asked about ex.: App Platform http timeout Managed Databases connection pool config value server_request_query Grace period while stopping App Platform containers during deployment It would be great if I could read about that details in some separated docs section.
