notify-me

Here, sendmail is wrapped by telegram-sendmail. Mail ends up in Telegram, not a mailbox.

Command

Use the wrapper binary:

/run/wrappers/bin/sendmail << 'ENDMAIL'
Subject: Short descriptive title
From: grok@whiterun
To: lucas59356@gmail.com
 
Message body here.
Multi-line is fine.
Keep it mostly ASCII to avoid UTF-8 queue issues.
ENDMAIL

• sendmail on PATH is usually the same wrapper.
• To: (and argv recipients) are mostly ignored; delivery goes to the configured Telegram chat.
• Success prints OK (enqueued for the daemon).

One-liner:

printf 'Subject: test\n\nbanana\n' | /run/wrappers/bin/sendmail

Prefer a heredoc for anything longer.

Repo wiring

• services.telegram-sendmail.enable = true on riverwood and whiterun
• module: nix/nodes/common/services/telegram_sendmail.nix
• creds: secrets/telegram_sendmail.env (sops; MAIL_TELEGRAM_TOKEN, MAIL_TELEGRAM_CHAT)
• other callers: nix/nodes/common/services/cloud-savegame.nix, bin/qrun
• identity in flake.nix: user lucasew, email lucas59356@gmail.com

When the user wants a ping

1. Minimal message with a clear Subject.
2. Pipe or heredoc into /run/wrappers/bin/sendmail.
3. Say it went out via sendmail (Telegram).

Skip mail / mutt / msmtp unless they ask. sendmail is the path here.
