# IMAP/SMTP Email Tool

Read, search, and manage email via IMAP protocol. Send email via SMTP. Supports Gmail, Outlook, 163.com, vip.163.com, 126.com, vip.126.com, 188.com, vip.188.com, and any standard IMAP/SMTP server.

## Configuration

Run the setup script to install dependencies and configure your email account:

```bash
bash setup.sh
```

If running commands manually without setup.sh, install dependencies first:

```bash
npm install --production
```

Configuration is stored at `~/.config/imap-smtp-email/.env` (survives skill updates). If no config is found there, the skill falls back to a `.env` file in the skill directory (for backward compatibility).

### Config file format

```bash
# Default account (no prefix)
IMAP_HOST=imap.gmail.com
IMAP_PORT=993
IMAP_USER=your@email.com
IMAP_PASS=your_password
IMAP_TLS=true
IMAP_REJECT_UNAUTHORIZED=true
IMAP_MAILBOX=INBOX

SMTP_HOST=smtp.gmail.com
SMTP_PORT=587
SMTP_SECURE=false
SMTP_USER=your@email.com
SMTP_PASS=your_password
SMTP_FROM=your@email.com
SMTP_REJECT_UNAUTHORIZED=true

# File access whitelist (security)
ALLOWED_READ_DIRS=~/Downloads,~/Documents
ALLOWED_WRITE_DIRS=~/Downloads
```

## Multi-Account

You can configure additional email accounts in the same config file. Each account uses a name prefix (uppercase) on all variables.

### Adding an account

Run the setup script and choose "Add a new account":

```bash
bash setup.sh
```

Or manually add prefixed variables to `~/.config/imap-smtp-email/.env`:

```bash
# Work account (WORK_ prefix)
WORK_IMAP_HOST=imap.company.com
WORK_IMAP_PORT=993
WORK_IMAP_USER=me@company.com
WORK_IMAP_PASS=password
WORK_IMAP_TLS=true
WORK_IMAP_REJECT_UNAUTHORIZED=true
WORK_IMAP_MAILBOX=INBOX
WORK_SMTP_HOST=smtp.company.com
WORK_SMTP_PORT=587
WORK_SMTP_SECURE=false
WORK_SMTP_USER=me@company.com
WORK_SMTP_PASS=password
WORK_SMTP_FROM=me@company.com
WORK_SMTP_REJECT_UNAUTHORIZED=true
```

### Using a named account

Add `--account <name>` before the command:

```bash
node scripts/imap.js --account work check
node scripts/smtp.js --account work send --to foo@bar.com --subject Hi --body Hello
```

Without `--account`, the default (unprefixed) account is used.

### Account name rules

- Letters and digits only (e.g., `work`, `163`, `personal2`)
- Case-insensitive: `work` and `WORK` refer to the same account
- The prefix in `.env` is always uppercase (e.g., `WORK_IMAP_HOST`)
- `ALLOWED_READ_DIRS` and `ALLOWED_WRITE_DIRS` are shared across all accounts (always unprefixed)

**Important for Gmail:**

- Requires Google Account with 2-Step Verification enabled

**Important for 163.com:**
- Use **authorization code** (授权码), not account password
- Enable IMAP/SMTP in web settings first

## Security Notes

- Configuration is stored at `~/.config/imap-smtp-email/.env` with `600` permissions (owner read/write only)
- **Gmail**: regular password is rejected — generate an App Password at https://myaccount.google.com/apppasswords
- For 163.com: use authorization code (授权码), not account password

## Troubleshooting

**Connection timeout:**
- Verify server is running and accessible
- Check host/port configuration

**Authentication failed:**
- Verify username (usually full email address)
- Check password is correct
- For 163.com: use authorization code, not account password
- For Gmail: regular password won't work — generate an App Password at https://myaccount.google.com/apppasswords

**TLS/SSL errors:**
- Match `IMAP_TLS`/`SMTP_SECURE` setting to server requirements
- For self-signed certs: set `IMAP_REJECT_UNAUTHORIZED=false` or `SMTP_REJECT_UNAUTHORIZED=false`
