We need more email diversity. Use your own email servers as often as you can. Monocultures of Apple/Google/MS is deterioration for the Internet.

And you don't need to run your own server in order to escape the big players. I have been a happy Fastmail customer for many years now.

I second Fastmail wholeheartedly. I moved multiple self-hosted (Postfix and Dovecot) environments to Fastmail and haven’t looked back. The only thing I lost was the ability to manually configure an address to bounce back.

Sending and receiving as a wildcard alias is fantastic, and Fastmail allowing that was the reason I finally moved. I held out on that feature for a long time. (You can also do this in Exchange Online if you want to run a convoluted and officially unsupported configuration.)

I only twice had any kind of RBL issues, and one was a motivating factor in moving. I also got tired of worrying about patching and CVEs. I do that enough for my work.
