If I'm trying to host my own email, it would seem that I need to make sure the reverse DNS is set up correctly. But where? The hosting provider (where I rent the machine) say's the domain is managed by Gandi, which is correct. But they don't offer a web UI to do this. Is this something I set up on my own machine?

@kensanata depends on the provider. I once had to file a support ticket to have rdns changed

@bremner I'm going to ask them again. 🤨
