The case for boring mail servers↗
Reasonable people disagree about running your own mail. This is the best version of the argument I’ve read for doing it anyway:
The interesting parts of a mail server are solved. What’s left is the boring part — keys that rotate, backups that restore, a dashboard someone actually looks at — and the boring part is the whole job. If you don’t want the boring part, you don’t want a mail server; you want an inbox. That’s fine. But be honest about which one you’re paying for.
I’d add: pick the software with the fewest moving parts you don’t understand. For me that turned out to be Stalwart.

Blue hour from the 4:10 to Sacramento. 0:06. A tiny ATProto PDS on a NUC↗

Exactly the write-up I wanted before I did mine. The migration section is the part nobody else documents.
Every clock in the house is now the same clock. Two NTP servers, one PPS-disciplined, and a rule that nothing gets to set its own time. It’s absurd and I’m very happy.
