AIMX
Self-hosted SMTP for AI agents. Your mail, your machine, end to end.
AIMX is a self-hosted, open-source SMTP mail server built specifically for AI agents. It stores emails as Markdown files with TOML frontmatter for easy LLM parsing, includes a built-in MCP server for agent integration, and delivers mail directly MTA-to-MTA with no third-party relays. It is distributed as a single Rust binary with a guided setup process.
AIMX installs as a single Rust binary, sets up a direct MTA-to-MTA SMTP server on your machine, stores mail as Markdown files, and exposes a stdio MCP server with tools for agents to list, read, send, and manage mail.
