# 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)

## Prerequisites

1. **Himalaya CLI** - the `himalaya` binary must already be on `PATH`. Check with `himalaya --version`.
   - **Recommended: v1.2.0 or newer.** Older releases can fail against some IMAP servers.
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 default
```

Or create `~/.config/himalaya/config.toml` manually:

```toml
[accounts.personal]
email = "you@example.com"
display-name = "Your Name"
default = true

backend.type = "imap"
backend.host = "imap.example.com"
backend.port = 993
backend.encryption.type = "tls"
backend.login = "you@example.com"
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 = "you@example.com"
message.send.backend.auth.type = "password"
message.send.backend.auth.cmd = "pass show email/smtp"
```

If using 163 mail, add `backend.extensions.id.send-after-auth = true`.

## Common Operations

### List Folders

```bash
himalaya folder list
```

### List Emails

```bash
himalaya envelope list                           # INBOX (default)
himalaya envelope list --folder "Sent"           # Specific folder
himalaya envelope list --page 1 --page-size 20   # With pagination
```

### Search Emails

```bash
himalaya envelope list from john@example.com subject meeting
```

### Read an Email

```bash
himalaya message read 42          # Plain text
himalaya message export 42 --full # Raw MIME
```
