 "page_title": "How to run a real mail server that receives mail for your domain with Sentio",
 "summary": "Install Sentio without Docker and run it as a systemd service on port 25.",
 "who": "A systems engineer who wants agents to receive mail on a domain they control and needs direct MX delivery.",
 "problem": "Relying on a hosted email API adds a dependency and limits control over the mail path.",
 "outcome": "Sentio runs as a systemd service accepting SMTP on ports 25, 465 and 587 and the REST API on port 8080.",
 "steps": [
  "Install build dependencies, then run `cargo build --release` in the cloned repo.",
  "Create the database with `sudo -u postgres createdb --owner=sentio sentio`.",
  "Run `./target/release/sentio-smtp --config config/default.toml migrate`.",
  "Copy the config with `sudo cp config/default.toml /etc/sentio/sentio.toml` and set server.hostname, database.url and storage.",
  "Install the unit with `sudo systemctl enable --now sentio-smtp` and check logs with `journalctl -u sentio-smtp -f`."
 ],
 "agent_prompt": "In the truespar/sentio repo, build with cargo build --release, run the migrate command against config/default.toml, and enable the sentio-smtp systemd service. Report the output of curl localhost:8080/health/ready. Verify that port 25 accepts a connection from an external test host for <your-domain>.",
