You had major issues delivering email to Outlook and Gmail, which represent the majority of all email recipients, and yet you're describing this as a success story with a tone that "anybody can do it".

I also tried to run my own mail server for years and I also had major issues delivering mail to Gmail and Outlook. Because of this I would never recommend self-hosting email to anybody else. Somehow you have my exact experience and your reaction to it is the complete opposite of my reaction. Weird.
