Some folks think that defederation is a bad thing. OK.
Here's a little experiment you can try at home.
- Stop using GMail, Hey, or whatever email service you're currently using.
- Set up your own mail server (there's instructions on the internet).
- When the instructions say to use a Remote Black List just ignore them.
- When the instructions say to validate domains, ignore those too.
- When the instructions say to set up SPF, DKIM, and DMARC just let those slide.
- Try to send / receive email
- Also try to read your inbox. For added benefit turn on all notifications for received mail.
Voila. Now you have an unfettered email experience.
And this, class, is why defederation is useful.
Please send your comments to the overworked TA in the back of the room.
