CLI to manage emails via IMAP/SMTP. Use `himalaya` to list, read, write, reply, forward, search, and organize emails from the terminal. Supports multiple accounts and message composition with MML (MIME Meta Language).

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

# 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 = "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"
…

How to install

The exact contents, by fingerprint

mdr add metaspartan/cybara/himalaya@sha256:ff9b88ffdba81024

The line at the top of this page pins the label git:20260218.a87179d, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
