And I _too_ run my own email server on my own domain. Though it resides on a dedicated server that I own in a data center somewhere in the Mid-West. The web mail cient it has is kind of crap though. I run a secondary "mail server" in my home, with a better webmail client, and is also configured with better spam protection and syncs with my android phone and outlook on my laptop, and that local email server that is configured to retrieve email from the data center server, along with retrieving email from gmail and a few other old email systems that I still have access too. Controlling my own email server, and my online identity that goes with it, is far better than entrusting it to someone like Google (who got about one step away from cancelling my Google account when they lost a phone I returned for repair, but that's a different story).
Interestingly, running my own server in a data center lets me run a permanent, private VPN from my home network to the data center, effectively hiding me away from any monitoring from my cable provider, using the DNS I want to make use of, blocking traffic I don't want leaking out or coming in. I have a smaller, less capable server in the UK also running a permanent, private VPN. Depending on which WiFi SSID I connect to within my home, determines if I appear as being in the US or the UK, which gives me access to different streaming services, different streaming content, different website experiences, etc.
