This one needs environment variables set before it will start: ATOMIC_MAIL_CREDENTIALS_DIR (Override default credential directory (~/.atomicmail/)), ATOMIC_MAIL_API_KEY (Existing API key — skips PoW registration), ATOMIC_MAIL_AUTH_URL (Override auth service base URL), ATOMIC_MAIL_API_URL (Override JMAP API base URL), ATOMIC_MAIL_INBOX_DOMAIN (Default inbox domain when inboxId has no @ (default: atomicmail.ai)). The author declared them in the registry entry; get the values from the project itself.
