I recently added email to my mastodon instance, and with that success, I'm ready to finally cut email ties with Google. I bought a new domain name and I'll set that up with postfix/dovecot/etc, then start moving all of my various internet accounts over to it.
The new domain has a .net TLD instead of the current .com TLD, and that's nice; it's more appropriate since I'm not running a business. Now I'm just waiting for the DNS changes to propagate.
