Meaning your contact doesn’t need to be online when you send the message. Your contact will get it automatically once they come online. So I can't send a message while my contact is offline, then go offline myself, and expect that my contact will receive it when they go online? This is quite limiting. How is PeerBox different from [Delta Chat](https://delta.chat/)?

Good question! The core difference is that Delta Chat still relies on email infrastructure (SMTP/IMAP), so your messages go through centralized servers you don't control. PeerBox is fully P2P. Your messages go straight from your machine to your contact's machine. No server in between, no account to create, no middleman. It combines SSH for encrypted transport and Tor for anonymity, so not even your ISP can see who you're talking to. It also works in deferred mode (like regular email, your contact gets the message when they come back online), strict P2P mode, or local network only. Contact management uses a dual-channel encrypted invitation system, so spam is simply impossible. And all local data is encrypted on disk with a self-destruct mechanism after 5 failed password attempts. It's a lightweight Python app for Linux, fully open source (AGPL).

Sounds like how SMS works. Doubt it's a problem if you're online or not after you send it.
