---
## Common Issues
### "SMTP connection verification failed"
```bash
# Restart ProtonBridge
sudo systemctl restart protonmail-bridge
sleep 30 # Wait for sync
sudo systemctl restart tractatus
```
### "Authentication failed"
- Check SMTP_PASS is the **Bridge password** (from `protonmail-bridge --cli > info`)
- NOT your Proton account password!
### Emails not received
- Check spam folder
- Verify Proton account has sending quota available
- Check ProtonBridge logs: `sudo journalctl -u protonmail-bridge -n 50`
---
## Monitoring
```bash
# ProtonBridge status
sudo systemctl status protonmail-bridge
# Email service logs
sudo journalctl -u tractatus -f | grep EmailService
# Port check
ss -tuln | grep 1026
```
---
**Done!** Email sending is now using ProtonBridge instead of SendGrid.

## Part 1: VPS Setup (One-time Configuration)
### Prerequisites
- Ubuntu 22.04 LTS VPS (already configured)
- Paid Proton account
- SSH access to production server: `vps-93a693da.vps.ovh.net`
### Step 1: Install ProtonBridge on VPS
```bash
# SSH to production server
ssh -i ~/.ssh/tractatus_deploy ubuntu@vps-93a693da.vps.ovh.net
# Install dependencies
sudo apt-get update
sudo apt-get install -y pass gnupg xvfb
# Download ProtonBridge (check for latest version)
wget https://proton.me/download/bridge/protonmail-bridge_3.0.21-1_amd64.deb
sudo dpkg -i protonmail-bridge_3.0.21-1_amd64.deb
sudo apt-get install -f # Fix any dependency issues
```
### Step 2: Configure GPG and Pass
```bash
# Generate GPG key (for pass credential manager)
gpg --gen-key
# - Use real name and email
# - Choose strong passphrase
# - Save the key ID shown
# Initialize pass with your GPG key ID
pass init "YOUR_GPG_KEY_ID"
```
### Step 3: Configure ProtonBridge
```bash
# Run ProtonBridge interactively (first time only)
protonmail-bridge --cli
# In ProtonBridge CLI:
> login
# Enter your Proton account credentials
> info
# IMPORTANT: Copy the Bridge password shown (different from Proton password)
# Example: cETwrBktTQMBQrMddzCFIg
# This is what SMTP_PASS will be
> exit
```
### Step 4: Create ProtonBridge Systemd Service
Create service file:
```bash
sudo nano /etc/systemd/system/protonmail-bridge.service
```
**Paste this configuration:**
```ini
[Unit]
Description=ProtonMail Bridge
After=network.target
[Service]
Type=simple
User=ubuntu
WorkingDirectory=/home/ubuntu
Environment="PATH=/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin"
Environment="HOME=/home/ubuntu"
Environment="DISPLAY=:99"
Environment="DBUS_SESSION_BUS_ADDRESS=unix:path=/run/user/1000/bus"
Environment="XDG_RUNTIME_DIR=/run/user/1000"
ExecStartPre=/bin/bash -c 'if ! pgrep -x "Xvfb" > /dev/null; then Xvfb :99 -screen 0 1024x768x24 > /dev/null 2>&1 & fi'
ExecStart=/usr/bin/protonmail-bridge --noninteractive
Restart=always
RestartSec=10
StandardOutput=journal
StandardError=journal
[Install]
WantedBy=multi-user.target
```
**Enable and start the service:**
```bash
# Reload systemd
sudo systemctl daemon-reload
# Enable for auto-start on boot
sudo systemctl enable protonmail-bridge
# Start the service
sudo systemctl start protonmail-bridge
# Check status
sudo systemctl status protonmail-bridge
# Should show: "active (running)"
```
### Step 5: Verify ProtonBridge Ports
```bash
# Test SMTP port (should connect)
nc -zv 127.0.0.1 1026
# Test IMAP port (should connect)
nc -zv 127.0.0.1 1144
# View ProtonBridge logs
sudo journalctl -u protonmail-bridge -f
```
---
## Part 2: Tractatus Application Configuration
### Environment Variables (Production)
**File**: `/var/www/tractatus/.env` (on production server)
Add these variables:
```bash
# Email Service Configuration
EMAIL_ENABLED=true
EMAIL_PROVIDER=proton
# SMTP Configuration (ProtonBridge)
SMTP_HOST=127.0.0.1
SMTP_PORT=1026 # Production port
SMTP_SECURE=false # localhost doesn't need TLS
SMTP_USER=your-tractatus-email@pm.me # Your Proton email
SMTP_PASS=YOUR_BRIDGE_PASSWORD # From ProtonBridge setup (Step 3)
EMAIL_FROM=your-tractatus-email@pm.me
# Newsletter URLs
NEWSLETTER_UNSUBSCRIBE_BASE_URL=https://agenticgovernance.digital/api/newsletter/unsubscribe
NEWSLETTER_PREFERENCES_BASE_URL=https://agenticgovernance.digital/newsletter/preferences
```
### Environment Variables (Development)
**File**: `/home/theflow/projects/tractatus/.env` (local dev machine)
```bash
# Email Service Configuration (DISABLED in dev)
EMAIL_ENABLED=false
# Optional: If you want to test locally with ProtonBridge
# SMTP_HOST=127.0.0.1
# SMTP_PORT=1025 # Development port
# SMTP_USER=your-email@pm.me
# SMTP_PASS=YOUR_BRIDGE_PASSWORD
```
---
## Part 3: Production Deployment Script
The existing `deploy.sh` script will handle deployment. ProtonBridge configuration is managed via `.env` on the production server.
### Manual Deployment Steps (if needed)
```bash
# From local machine
cd /home/theflow/projects/tractatus
# Deploy email service changes
./scripts/deploy.sh src/services/email.service.js --restart
# Or full deployment
./scripts/deploy.sh
```
---
## Part 4: Testing & Verification
### Test 1: Check ProtonBridge Status
```bash
# On production server
sudo systemctl status protonmail-bridge
# Should show:
# Active: active (running) since...
# Uptime: X days
```
### Test 2: Test SMTP Connection
```bash
# On production server
telnet 127.0.0.1 1026
# Should connect successfully
# Type QUIT to exit
```
### Test 3: Test Email Sending (Node.js)
```bash
# On production server
cd /var/www/tractatus
# Quick test script
node -e "
const nodemailer = require('nodemailer');
const transporter = nodemailer.createTransport({
host: '127.0.0.1',
port: 1026,
secure: false,
auth: {
user: 'your-email@pm.me',
pass: 'YOUR_BRIDGE_PASSWORD'
},
tls: { rejectUnauthorized: false }
});
transporter.sendMail({
from: 'your-email@pm.me',
to: 'test@example.com',
subject: 'ProtonBridge Test',
text: 'Test email from Tractatus'
}, (err, info) => {
if (err) {
console.error('Error:', err);
} else {
console.log('Success! Message ID:', info.messageId);
}
process.exit(err ? 1 : 0);
});
"
```
### Test 4: Check Application Health
```bash
# Test health endpoint
curl -s https://agenticgovernance.digital/health/detailed | jq '.services.email'
# Should show:
# {
# "status": "running",
# "smtp": {
# "status": "connected",
# "host": "127.0.0.1",
# "port": "1026"
# }
# }
```
### Test 5: Send Test Newsletter
1. Access newsletter administration interface (admin authentication required)
2. Fill in newsletter form (use JSON for content)
3. Click "Send Test" button
4. Enter your email address
5. Check inbox for test email
---
## Monitoring & Maintenance
### View ProtonBridge Logs
```bash
# Real-time logs
sudo journalctl -u protonmail-bridge -f
# Last 50 lines
sudo journalctl -u protonmail-bridge -n 50
# Logs from specific date
sudo journalctl -u protonmail-bridge --since "2025-11-03"
```
### View Application Email Logs
```bash
# Tractatus uses systemd service
sudo journalctl -u tractatus -f | grep EmailService
# Or check PM2 logs (if using PM2)
pm2 logs tractatus-prod | grep EmailService
```
### Restart Services
```bash
# Restart ProtonBridge (rarely needed)
sudo systemctl restart protonmail-bridge
# Restart Tractatus application
sudo systemctl restart tractatus
```
### Health Check Commands
```bash
# Check ProtonBridge is listening
ss -tuln | grep -E '1026|1144'
# Check application connection
curl -s http://localhost:9000/health/detailed | jq .
# Test SMTP auth
nc -zv 127.0.0.1 1026
```
---
## Troubleshooting
### Problem: "SMTP connection verification failed"
**Cause**: ProtonBridge not running or not fully synced
**Solution**:
```bash
# Check ProtonBridge status
sudo systemctl status protonmail-bridge
# Check if ports are listening
ss -tuln | grep 1026
# Restart ProtonBridge
sudo systemctl restart protonmail-bridge
# Wait 30 seconds for mailbox sync
sleep 30
# Restart application
sudo systemctl restart tractatus
```
### Problem: "Authentication failed"
**Cause**: Incorrect Bridge password (not Proton account password)
**Solution**:
```bash
# Get correct Bridge password
protonmail-bridge --cli
> info
> exit
# Update .env with correct SMTP_PASS
nano /var/www/tractatus/.env
# Restart application
sudo systemctl restart tractatus
```
### Problem: Email sending works but emails not received
**Cause**: SPF/DKIM records not configured
**Solution**: ProtonMail handles SPF/DKIM automatically - no DNS changes needed. Check spam folder.
### Problem: ProtonBridge keeps restarting
**Cause**: GPG/pass configuration issue
**Solution**:
```bash
# Check GPG keys
gpg --list-keys
# Reinitialize pass if needed
pass init "YOUR_GPG_KEY_ID"
# Reconfigure ProtonBridge
protonmail-bridge --cli
> login
> info
> exit
```
---
## Port Reference
| Service | Environment | Port | Protocol |
|---------|-------------|------|----------|
| ProtonBridge SMTP | Production | 1026 | STARTTLS |
| ProtonBridge SMTP | Development | 1025 | STARTTLS |
| ProtonBridge IMAP | Production | 1144 | STARTTLS |
| ProtonBridge IMAP | Development | 1143 | STARTTLS |
**Note**: Tractatus EmailService automatically detects production vs development and uses the correct port.
---
## Security Considerations
1. **Localhost Only**: ProtonBridge only binds to 127.0.0.1 - not accessible externally
2. **No TLS Needed**: Localhost connections are secure without TLS
3. **Bridge Password**: Different from Proton account credentials (generated by ProtonBridge)
4. **Email Disabled in Dev**: Prevents accidental email sends during development
5. **Rate Limiting**: EmailService enforces 10 emails/second max
6. **Connection Pooling**: Reuses connections for efficiency
---
## Comparison: ProtonBridge vs SendGrid
| Feature | ProtonBridge | SendGrid |
|---------|-------------|----------|
| **Cost** | Paid Proton account (~$4/month) | Free: 100/day, Paid: $19.95/month |
| **Privacy** | End-to-end encrypted | Third-party data access |
| **Deliverability** | Good (uses Proton infrastructure) | Excellent (dedicated IPs, reputation) |
| **Setup Complexity** | Moderate (requires VPS setup) | Easy (API key only) |
| **Sending Limits** | 1,000/day (Proton paid) | 50,000/month (paid tier) |
| **Control** | Self-hosted bridge | Cloud service |
| **Reliability** | Depends on VPS uptime | 99.9% SLA |
---
## Migration from SendGrid
Already completed! The changes include:
1. ✅ Replaced `@sendgrid/mail` with `nodemailer`
2. ✅ Updated EmailService with ProtonBridge configuration
3. ✅ Added smart port detection (prod vs dev)
4. ✅ Implemented connection pooling and rate limiting
5. ✅ Added EMAIL_ENABLED flag for dev/prod separation
No API changes - existing newsletter functionality works identically.
---
## Next Steps
1. **Install ProtonBridge on production server** (Part 1)
2. **Update production .env** with Bridge credentials (Part 2)
3. **Deploy updated EmailService** (Part 3)
4. **Test email sending** (Part 4)
5. **Monitor for 24 hours** to ensure stability
