# Proton Mail Bridge

Headless Proton Mail Bridge running on CT 104 — exposes ProtonMail account as SMTP/IMAP endpoints for local services (n8n, Infisical, etc.).

## Stack

- **Host**: CT 104 (`docker`, 192.168.1.40), `/opt/stacks/proton-bridge/docker-compose.yml`
- **Image**: `shenxn/protonmail-bridge:latest`
- **SMTP**: `192.168.1.40:1025`
- **IMAP**: `192.168.1.40:1143`
- **Config volume**: `proton-bridge_proton_config`

## Initial login (one-time, interactive)

```bash
ssh root@192.168.1.40
docker exec -it proton-bridge /bin/bash
protonmail-bridge --cli
# Commands: login → (enter Proton credentials) → list (note bridge SMTP password)
# exit
```

After login the bridge stores credentials in the volume and runs headlessly on restart.

## SMTP credentials for other services

Once logged in, run `list` inside the CLI to get:
- **SMTP host**: `192.168.1.40`
- **SMTP port**: `1025`
- **SMTP user**: your Proton email address
- **SMTP password**: the bridge-generated password (not your Proton login password)
- **IMAP host**: `192.168.1.40`
- **IMAP port**: `1143`

## Ops

```bash
# CT 104
cd /opt/stacks/proton-bridge
docker compose up -d --force-recreate proton-bridge
docker logs proton-bridge -f
```
