# IMAP Email Reader

Read, search, and manage email via IMAP protocol. Supports ProtonMail Bridge, Gmail IMAP, and any standard IMAP server.

## Quick Start

**Check for new emails:**
```bash
node skills/imap-email/scripts/imap.js check
```

**Fetch specific email:**
```bash
node skills/imap-email/scripts/imap.js fetch <uid>
```

**Mark as read:**
```bash
node skills/imap-email/scripts/imap.js mark-read <uid>
```

**Search mailbox:**
```bash
node skills/imap-email/scripts/imap.js search --from "sender@example.com" --unseen
```

## Configuration

Create `.env` in the skill folder or set environment variables:

```bash
IMAP_HOST=127.0.0.1          # Server hostname
IMAP_PORT=1143               # Server port
IMAP_USER=your@email.com
IMAP_PASS=your_password
IMAP_TLS=false               # Use TLS/SSL connection
IMAP_REJECT_UNAUTHORIZED=false  # Set to false for self-signed certs (optional)
IMAP_MAILBOX=INBOX           # Default mailbox
```

**ProtonMail Bridge setup:**
- Install and run ProtonMail Bridge
- Use `127.0.0.1:1143` for IMAP
- Password is generated by Bridge (not your ProtonMail password)
- TLS: Use `false` (Bridge uses STARTTLS)
- `REJECT_UNAUTHORIZED`: Set to `false` (Bridge uses self-signed cert)

**Gmail IMAP setup:**
- Host: `imap.gmail.com`
- Port: `993`
- TLS: `true`
- Enable "Less secure app access" or use App Password
- `REJECT_UNAUTHORIZED`: Omit or set to `true` (default)

## Cron Integration

Set up periodic email checking with Clawdbot cron:

```bash
# Check email every 15 minutes, deliver to iMessage
clawdbot cron add \
  --name "email-check" \
  --cron "*/15 * * * *" \
  --session isolated \
  --message "Check for new ProtonMail emails and summarize them" \
  --deliver \
  --channel imessage \
  --to "+15085600825"
```

Inside the isolated session, the agent can run:
```bash
node /Users/mike/clawd/skills/imap-email/scripts/imap.js check --limit 5
```

## Workflow Examples

1. Run `check --limit 10 --recent 12h`
2. Summarize unread emails from overnight
3. Deliver summary to preferred channel

**Check recent emails from specific sender:**
1. Run `search --from "important@company.com" --recent 24h`
2. Fetch full content if needed
3. Mark as read after processing

**Hourly urgent email check:**
1. Run `search --recent 1h --unseen`
2. Filter for important keywords
3. Extract action items
4. Deliver notification if urgent

**Weekly digest:**

## Dependencies

Install in skill folder:
```bash
cd skills/imap-email
npm install imap-simple dotenv
```

Or install globally:
```bash
npm install -g imap-simple dotenv
```

## Security Notes

- Store credentials in `.env` (add to `.gitignore`)
- ProtonMail Bridge password is NOT your account password
- Bridge must be running for ProtonMail IMAP access
- Consider using app-specific passwords for Gmail

## Troubleshooting

**Connection timeout:**
- Verify IMAP server is running and accessible
- Check host/port configuration
- Test with: `telnet <host> <port>`

**Authentication failed:**
- Verify username (usually full email address)
- Check password is correct
- For ProtonMail Bridge: use Bridge-generated password, not account password
- For Gmail: use App Password if 2FA is enabled

**TLS/SSL errors:**
- Match `IMAP_TLS` setting to server requirements (true for SSL, false for STARTTLS)
- For self-signed certs (e.g., ProtonMail Bridge): set `IMAP_REJECT_UNAUTHORIZED=false`
- Check port matches TLS setting (993 for SSL, 143 for STARTTLS)

**Empty results:**
- Verify mailbox name (case-sensitive)
- Check search criteria
- List mailboxes with `list-mailboxes`
