The author details their attempt to set up a private mail server using Stalwart on an Ubuntu VPS. While the configuration of essential DNS records like SPF, DKIM, and DMARC was successful and the server avoided becoming an open relay, the project failed due to ISP restrictions blocking port 25. This meant that although outgoing emails could be sent, no incoming mail could ever reach the server. The article concludes that self-hosting email is complicated by external infrastructure factors beyond a user's control, making dedicated paid services often more practical for most people.
