Is there a hosted Mastodon solution, where you can bring your own domain name and they do the rest, like how I can bring my domain name to any number of email providers?
Discussions of running your own mail server make it sound like it's difficult because you have to get Microsoft and Google to accept your mail and they tend to let it go into the spam folder and not respond to you.
Will mastodon.social federate with HellsMaddy.social? Maybe. Can you use me@hellsmaddy.com? No.
