> If you just want a reliable mail service, just use https://fastmail.com. If you want even more freedom and configurations, do try to set up a mail server. But it is hard. A bit hard.

I used to run my own mail server, but I eventually migrated to Fastmail. I liked then because their software stack was similar enough to mine (compatible filter rules) and I knew where to find their admin on IRC.

The reason I made the switch is because I was sick and tired of my Email reliability depending on the reliability of my home Internet connection, and my co-lo/remote-hosting situation (at the time) had different reliability issues I didn't want to risk.
