# Himalaya Email CLI

Himalaya is a CLI email client that lets you manage emails from the terminal using IMAP, SMTP, Notmuch, or Sendmail backends.

## References

- `references/configuration.md` (config file setup + IMAP/SMTP authentication)
- `references/message-composition.md` (MML syntax for composing emails)

## Prerequisites

1. Himalaya CLI installed (`himalaya --version` to verify)
2. A configuration file at `~/.config/himalaya/config.toml`
3. IMAP/SMTP credentials configured (password stored securely)

## Configuration Setup

Run the interactive wizard to set up an account:
```bash
himalaya account configure
```

Or create `~/.config/himalaya/config.toml` manually:
```toml
[accounts.personal]
email = "[email protected]"
display-name = "Your Name"
default = true

backend.type = "imap"
backend.host = "imap.example.com"
backend.port = 993
backend.encryption.type = "tls"
backend.login = "[email protected]"
backend.auth.type = "password"
backend.auth.cmd = "pass show email/imap"  # or use keyring

message.send.backend.type = "smtp"
message.send.backend.host = "smtp.example.com"
message.send.backend.port = 587
message.send.backend.encryption.type = "start-tls"
message.send.backend.login = "[email protected]"
message.send.backend.auth.type = "password"
message.send.backend.auth.cmd = "pass show email/smtp"
```

## Common Operations

```

## Output Formats

Most commands support `--output` for structured output:

himalaya envelope list --output plain
```

```bash
RUST_LOG=debug himalaya envelope list
```

```

## Tips

- Use `himalaya --help` or `himalaya <command> --help` for detailed usage.
- Message IDs are relative to the current folder; re-list after folder changes.
- For composing rich emails with attachments, use MML syntax (see `references/message-composition.md`).
- Store passwords securely using `pass`, system keyring, or a command that outputs the password.
