I want to encourage everybody to set up their own e-mail infrastructure, as it's both fun, rewarding and useful.
However, deliverability has become really difficult. It seems during the ten years since I last ran my own e-mail, it has become an oligopoly. I have SPF, DKIM, DMARC and reverse DNS, my IP is not on any blacklists, and still my e-mail ends up spam listed in both Gmail and Hotmail. It seems to be getting a worse treatment by Hotmail but it's hard to say due to the small volume.

It is getting better but slowly, it seems.
