Nevermind, @Melvin. I see that you didn't quite understand what I was asking for. I probably explained it badly.

I use 1984.is to manage the DNS zones of my domains and I use Yandex.Connect to send and receive e-mails with mail addresses like [email protected]. I don't want to use the DNS of the hosting provider therefore, nor their mail server for mail business. I do however need to be able to use their other features like the TLS certificates for hosted sites. I have tried hosts that wouldn't let you even sign up with them if you didn't use their DNS servers.
