## Step 0: Setup

### Quick Start (Single Account)

```bash
# Set 2 environment variables and you're ready
export EMAIL_ADDRESS="your@qq.com"
export EMAIL_AUTH="your_authorization_code"
```

> ⚠️ `export` 设置的变量在当前 shell 及所有子进程可见（包括 ps 命令、CI 日志、崩溃报告）。
> 用完建议 `unset EMAIL_AUTH`，或使用 `.env` 文件 + `source` 替代一次性 export。

### Multi-Account Setup

```bash
# QQ Mail
export EMAIL_QQ="your@qq.com"
export EMAIL_QQ_AUTH="qq_auth_code"

# 163 Mail
export EMAIL_163="your@163.com"
export EMAIL_163_AUTH="163_client_password"

# Gmail
export EMAIL_GMAIL="your@gmail.com"
export EMAIL_GMAIL_AUTH="gmail_app_password"
```

### Provider Auth Guide

How to get authorization codes for each provider → `references/providers.md`

> ⚠️ 授权码等同于邮箱密码，拥有它可以收发你的所有邮件。不要分享给他人，不要在公共终端设置。

### Persistent Config

**IMPORTANT: Never store email credentials in plaintext files.** Use your system's secure credential manager or session-only environment variables.

```bash
# Option A: Session-only (recommended for security)
# Set environment variables in your current shell session only.
# Credentials will NOT persist after the session ends.
export EMAIL_ADDRESS="your@qq.com"
export EMAIL_AUTH="your_auth_code"

# Option B: Keychain / secret manager
# macOS: Use `security add-internet-password`
# Linux: Use `secret-tool store` (libsecret)
# Windows: Use Windows Credential Manager

# Option C: Restricted file (if persistent config is required)
# Create a file with restricted permissions that only you can read:
mkdir -p ~/.emailbox && touch ~/.emailbox/credentials
chmod 600 ~/.emailbox/credentials
# Then add your credentials:
# EMAIL_ADDRESS=your@qq.com
# EMAIL_AUTH=your_auth_code
# 
# Before running emailbox commands:
# source ~/.emailbox/credentials
```

```

---

## Step 3: Search Email

```bash
# Search by keyword (searches subject, from, AND body)
python3 scripts/receive_mail.py --search "contract" --provider qq

# Search by sender
python3 scripts/receive_mail.py --search "" --from-filter "zhangsan@company.com"

# Search by date range
python3 scripts/receive_mail.py --search "report" --since "2026-04-01"

# Combined search
python3 scripts/receive_mail.py --search "invoice" --from-filter "finance@company.com" --since "2026-04-01" --count 5
```

### IMAP Folders

Access folders beyond INBOX:
```bash
python3 scripts/receive_mail.py --list --folder "Sent Items"
python3 scripts/receive_mail.py --list --folder "Drafts"
python3 scripts/receive_mail.py --list --folder "Trash"
```

Common folder names:

  --forward-subject "Original Subject" \
  --forward-to "me@company.com" \
  --provider qq
```

---

## Step 5: Document Data Integration

Combine other Skills' output with email sending.

Detailed workflows → `references/integrations.md`

### Common Patterns

```
1. Excel → Email: Read data → HTML table → send
2. OCR → Email: Recognize invoice → extract key info → send
3. PDF → Email: Process PDF → summary + attachment → send
4. Data Analysis → Email: Analyze data → conclusions → send
5. Scheduled Report: Generate content → schedule → send
```

### Excel Data → Email Example

```bash
# Step 1: Read and format data (use excel-studio or python3)
# Step 2: Save HTML content using a template from references/templates.md
# Step 3: Send
python3 scripts/send_mail.py \
  --to "boss@company.com" \
  --subject "Sales Report $(date +%Y%m%d)" \
  --body-file "${OPENCLAW_WORKSPACE:-$PWD}/.emailbox_body.txt" \
  --html-file "${OPENCLAW_WORKSPACE:-$PWD}/.emailbox_body.html" \
  --attach "/path/to/report.xlsx" \
  --provider qq
```

### Related Skills

| Skill | Integration | Scenario |
|-------|------------|----------|
| china-doc-ocr | OCR → email content | Invoice/contract recognition then email |
| excel-studio | Excel → table email | Data reports, financial statements |
| pdf-studio | PDF → email attachment | PDF report sending |
| data-analyzer | Analysis → email conclusions | Data insight notifications |

---

## Step 6: Schedule Email

### Send at Specific Time

```bash
python3 scripts/schedule_mail.py \
  --schedule --at "2026-04-19 09:00" \
  --to "boss@company.com" \
  --subject "Daily Report - 2026-04-19" \
  --body "Today's work summary..." \
  --provider qq
```

### Send in N Minutes

```bash
python3 scripts/schedule_mail.py \
  --schedule --in 30 \
  --to "client@example.com" \
  --subject "Follow up" \
  --body "Following up on our meeting..." \
  --provider 163
```

### Manage Scheduled Emails

```bash
# View scheduled emails
python3 scripts/schedule_mail.py --list-scheduled

# Cancel a scheduled email
python3 scripts/schedule_mail.py --cancel SCHEDULE_ID

# Manually process due emails
python3 scripts/schedule_mail.py --process-queue
```

### Auto-Processing (Manual Setup Only)

**⚠️ The schedule script will NEVER modify your crontab automatically.** You must manually confirm any crontab changes.

```bash
# Step 1: Check your current crontab first
crontab -l > ~/crontab_backup.txt

# Step 2: Add the emailbox processor manually (review before adding!)
# Add this line to your crontab ONLY if you want auto-processing:
# * * * * * python3 /path/to/emailbox/scripts/schedule_mail.py --process-queue

# Step 3: To remove later, edit your crontab and remove the line
```

## Error Handling

```
Error                              → Solution
──────────────────────────────────────────────────────────
SMTP auth failed                   → Check authorization code, see providers.md
IMAP connection failed             → Verify IMAP enabled, check network
Connection timeout                 → Gmail/Yahoo/iCloud need VPN in China
SMTP auth code error (QQ/163)     → Use authorization code, NOT login password
Sending rate limit                 → QQ: 1/min, 500/day; 163: 200/day; Gmail: 500/day
Attachment too large               → QQ: 50MB; Gmail: 25MB; Outlook: 20MB
IMAP not enabled                   → Enable in email settings, see providers.md
163 requires phone verification    → Verify via SMS, wait 5-10 minutes
```

## Privacy & Security

- Direct IMAP/SMTP connection to email servers, no third-party data transfer
- **Credentials should be stored in environment variables only, NOT in plaintext files**
- ⚠️ 环境变量中的凭据可能通过 shell history、进程列表（`ps aux`）、CI 日志、崩溃报告泄露
- 用完授权码后建议 `unset EMAIL_AUTH` 清除当前 shell 的凭据
- Use provider-specific app passwords/authorization codes (NOT your login password)
- Authorization codes are email-specific, cannot be used to log into webmail
- Schedule queue stored in `~/.emailbox/queue/` — review and clean up regularly
- **This skill will NEVER modify your crontab or system scheduler without your explicit manual action**
- For maximum security, use a dedicated email account for automated sending

## Notes

- Requires IMAP/SMTP service enabled and authorization code configured
- Gmail/Yahoo/iCloud require VPN in mainland China
- QQ Mail limits: 500 emails/day, 1 email/minute
- 163/126 Mail limits: 200 emails/day
- Attachment size limits vary by provider (QQ: 50MB, Gmail: 25MB, Outlook: 20MB)
- Scheduled sending uses a local queue in `~/.emailbox/queue/`; processing requires manual crontab setup
- **Always use app passwords/authorization codes, never your real email login password**

Attachment too large               → QQ: 50MB; Gmail: 25MB; Outlook: 20MB

Privacy & Security

Direct IMAP/SMTP connection to email servers, no third-party data transfer
Credentials should be stored in environment variables only, NOT in plaintext files
⚠️ 环境变量中的凭据可能通过 shell history、进程列表（ps aux）、CI 日志、崩溃报告泄露
用完授权码后建议 unset EMAIL_AUTH 清除当前 shell 的凭据
Use provider-specific app passwords/authorization codes (NOT your login password)
Authorization codes are email-specific, cannot be used to log into webmail
Schedule queue stored in ~/.emailbox/queue/ — review and clean up regularly
This skill will NEVER modify your crontab or system scheduler without your explicit manual action
For maximum security, use a dedicated email account for automated sending

Notes

Requires IMAP/SMTP service enabled and authorization code configured
Gmail/Yahoo/iCloud require VPN in mainland China
QQ Mail limits: 500 emails/day, 1 email/minute
163/126 Mail limits: 200 emails/day
Attachment size limits vary by provider (QQ: 50MB, Gmail: 25MB, Outlook: 20MB)
Scheduled sending uses a local queue in ~/.emailbox/queue/; processing requires manual crontab setup
Always use app passwords/authorization codes, never your real email login password
