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.

A self-hosted, GitHub-compatible API server designed for agents, automation, and developer workflows. It allows existing GitHub clients to work with owned repositories by exposing REST v3, GraphQL v4, OAuth device flow, and Git Smart HTTP while utilizing real bare Git repositories and TiDB/MySQL-compatible storage for metadata.
Most users treat self-hosted large language models like a simple chat interface, effectively limiting their potential to basic question-and-answer tasks. The author suggests moving beyond this ChatGPT clone approach by integrating local AI as an always-on intelligence layer within your digital workflow. By treating the LLM as a backend engine rather than just a website, you can gain superior privacy and control while automating complex tasks across your files and devices.
