apple-mail-search（Apple mail 搜索）

Apple Mail Search

Direct SQL search against Apple Mail's Envelope Index database. Queries complete in under 0.5 seconds against all mail accounts.

When to use

• You need to find emails by subject, sender, or date.
• You want to list available mailboxes and accounts.
• You need fast search without opening Mail.app.
• You want to read email content from specific messages.

How it works

1. Reads Apple Mail's Envelope Index SQLite database at ~/Library/Mail/V10/MailData/
2. Joins messages with subjects, addresses, and mailboxes tables
3. Returns metadata (subject, sender, date, mailbox) for matching messages
4. Can retrieve full email content from .emlx files when needed

The database is always up-to-date as Mail.app writes to it in real-time.

Usage

Performance

Database Schema

Key tables in Envelope Index:

• messages - Message metadata (sender, subject refs, dates, flags)
• subjects - Subject text (normalized)
• addresses - Email addresses and display names
• mailboxes - Mailbox URLs (account/folder structure)
• summaries - Email preview snippets

Security Considerations

• Read-only access to Mail's SQLite database
• No data is modified or written
• No network requests; all local operations
• Searches happen locally; nothing leaves your machine

Troubleshooting

• "Database not found": Ensure Apple Mail has been opened at least once
• "Database is locked": Mail.app may be syncing; retry in a moment
• Empty results: Check account/mailbox names with accounts and mailboxes commands
• Missing message content: Some messages may be partially downloaded (IMAP); full content requires Mail.app to download

Limitations

• Body search uses the summaries table (email previews), not full message content
• For full-text body search, use read --id to get complete message content
• Attachments are not searchable via this tool
• Deleted messages (in Trash) may still appear until permanently deleted
