@Lobster I don't have anything to offer I'm afraid but I'm interested in how you get on for sure. Whenever I've looked into it I always get hung up on it depending on some kind of mail server. I'd love to host my own mail server too but it seems like too much work from what I see online.
@Lobster I am waiting for @nextcloud Social app release to host my fediverse instance. I hope, it's gonna be lightweight and easy to mange.
