# Nanobot Email Assistant: End-to-End Guide
This guide explains how to run nanobot as a real email assistant with explicit user permission and optional automatic replies.
## 1. What This Feature Does
- Read unread emails via IMAP.
- Let the agent analyze/respond to email content.
- Send replies via SMTP.
- Enforce explicit owner consent before mailbox access.
- Let you toggle automatic replies on or off.
## 2. Permission Model (Required)
`channels.email.consentGranted` is the hard permission gate.
- `false`: nanobot must not access mailbox content and must not send email.
- `true`: nanobot may read/send based on other settings.
Only set `consentGranted: true` after the mailbox owner explicitly agrees.
## 3. Auto-Reply Mode
`channels.email.autoReplyEnabled` controls outbound automatic email replies.
- `true`: inbound emails can receive automatic agent replies.
- `false`: inbound emails can still be read/processed, but automatic replies are skipped.
Use `autoReplyEnabled: false` when you want analysis-only mode.
## 4. Required Account Setup (Gmail Example)
1. Enable 2-Step Verification in Google account security settings.
2. Create an App Password.
3. Use this app password for both IMAP and SMTP auth.
Recommended servers:
- IMAP host/port: `imap.gmail.com:993` (SSL)
- SMTP host/port: `smtp.gmail.com:587` (STARTTLS)
## 5. Config Example
Edit `~/.nanobot/config.json`:
```json
{
"channels": {
"email": {
"enabled": true,
"consentGranted": true,
"imapHost": "imap.gmail.com",
"imapPort": 993,
"imapUsername": "you@gmail.com",
"imapPassword": "${NANOBOT_EMAIL_IMAP_PASSWORD}",
"imapMailbox": "INBOX",
"imapUseSsl": true,
"smtpHost": "smtp.gmail.com",
"smtpPort": 587,
"smtpUsername": "you@gmail.com",
"smtpPassword": "${NANOBOT_EMAIL_SMTP_PASSWORD}",
"smtpUseTls": true,
"smtpUseSsl": false,
"fromAddress": "you@gmail.com",
"autoReplyEnabled": true,
"pollIntervalSeconds": 30,
"markSeen": true,
"allowFrom": ["trusted.sender@example.com"]
}
}
}
```
## 6. Set Secrets via Environment Variables
In the same shell before starting gateway:
```bash
read -s "NANOBOT_EMAIL_IMAP_PASSWORD?IMAP app password: "
echo
read -s "NANOBOT_EMAIL_SMTP_PASSWORD?SMTP app password: "
echo
export NANOBOT_EMAIL_IMAP_PASSWORD
export NANOBOT_EMAIL_SMTP_PASSWORD
```
If you use one app password for both, enter the same value twice.
## 7. Run and Verify
Start:
```bash
cd /Users/kaijimima1234/Desktop/nanobot
PYTHONPATH=/Users/kaijimima1234/Desktop/nanobot .venv/bin/nanobot gateway
```
Check channel status:
```bash
PYTHONPATH=/Users/kaijimima1234/Desktop/nanobot .venv/bin/nanobot channels status
```
Expected behavior:
- `enabled=true + consentGranted=true + autoReplyEnabled=true`: read + auto reply.
- `enabled=true + consentGranted=true + autoReplyEnabled=false`: read only, no auto reply.
- `consentGranted=false`: no read, no send.
## 8. Commands You Can Tell Nanobot
Once gateway is running and email consent is enabled:
1. Summarize yesterday's emails:
```text
summarize my yesterday email
```
or
```text
!email summary yesterday
```
2. Send an email to a friend:
```text
!email send friend@example.com | Subject here | Body here
```
or
```text
send email to friend@example.com subject: Subject here body: Body here
```
Notes:
- Sending command always performs a direct send (manual action by you).
- If `consentGranted` is `false`, send/read are blocked.
- If `autoReplyEnabled` is `false`, automatic replies are disabled, but direct send command above still works.
## 9. End-to-End Test Plan
1. Send a test email from an allowed sender to your mailbox.
2. Confirm nanobot receives and processes it.
3. If `autoReplyEnabled=true`, confirm a reply is delivered.
4. Set `autoReplyEnabled=false`, send another test email.
5. Confirm no auto-reply is sent.
6. Set `consentGranted=false`, send another test email.
7. Confirm nanobot does not read/send.
## 10. Security Notes
- Never commit real passwords/tokens into git.
- Prefer environment variables for secrets.
- Keep `allowFrom` restricted whenever possible.
- Rotate app passwords immediately if leaked.
## 11. PR Checklist
- [ ] `consentGranted` gating works for read/send.
- [ ] `autoReplyEnabled` toggle works as documented.
- [ ] README updated with new fields.
- [ ] Tests pass (`pytest`).
- [ ] No real credentials in tracked files.
