If you're wondering, how to do this, with your own relay, or where to rent a relay to do this, I can recommend relay.tools. Great dev, solid service, quick responses on issues or server attacks, independent cloud, etc. A lot of the stuff I described, only became possible to do because nostr:npub10npj3gydmv40m70ehemmal6vsdyfl7tewgvz043g54p0x23y0s8qzztl5h invented it. He has some interesting new features coming up soon, as well. 👀

You can also use his open-source libraries, to manage your self-hosted relay.
