I am writing this with sadness and frustration in my heart. The only issue I have found seriously limiting my ability to use my own self hosted email server is the deliberate decision of Google, Yahoo and Microsoft to make it hard for me to do so. Their decision is essentially un-appealable. I still get hotmail complaints about spam being sent from an IP I do not own anymore. For the life of me I could not find a way to solve this. Yes I did remove that address from their “responsible domain owner nonsense thingy” to no avail. Often times I would send an email to a domain owned by one of the big three and that email would just disappear. No bounce back at all. The recipient would not even see it in their spam folder. They tell you to implement various technical solution line DMARC and DKIM but in the end what really matters is the arbitrary and capricious decision of these three companies against which there is no recourse. I agree that hosting your own email server is important but this is a battle that I gave up fighting.
