Does anybody here self-host a mail-by-proxy solution? If so, I'm interested to hear about your setup, experiences and any drawbacks. I have a custom domain and a hosted email service with a very small amount of storage. I'd like to host something locally so that I can keep all my email without stressing about the space. I also want to be able to use email on my phone and computer and a web interface for tablets or while traveling. Finally, I'd like emails that I send to be stored locally so I can search it. Does anybody else already do something like this? I can forge my own path, but oftentimes, somebody else is already doing it better.
I can't speak to the quality outlook, but from what I understand about enshittification, it typically requires a self-serving entity like a corporation whose interests are not in alignment with its customers/consumers/userbase. In some of Mr. Doctrow's writings, he indicates that federating cans be a "circuit breaker" for enshittification.
In a well federated platform, when one node begins to act counter to its users, the users can easily move nodes/instances. This is one of the reasons why there needed to be a law to allow phone number portability. Email is similar, but only if you own your own domain. Look for Cory Doctrow's writings on BlueSky for more examples.
