LAN Chat Software: delta chat

I found that using email protocols is better suited for scenarios where participants may go offline at any time. So I chose delta chat , which supports IP-based email formats such as remoon@[2001:ff::1], making it a perfect fit.

However, current open-source mail servers require TLS by default, while TLS is not needed within a well-net network. Therefore, a dedicated mail server needs to be built specifically for this internal communication scenario.

Unfortunately, I don’t have time to work on this right now. If you know any suitable implementation, feel free to recommend it in the issues.

A recommended mail server implementation should meet the following requirements:

1. Support IP-based email addresses
2. Rewrite the From email domain into an internal IP format, for example: remoon@remoon.net → remoon@[2001:ff::1], to unify identity
3. Support message re-delivery, since other peers may go offline at any time
4. Possibly other features?

Frontend Interface

After trying various approaches, using a web UI turned out to be the fastest option.

Todo

• Plugin mechanism. _hookjs is not very ideal, but it allows implementing features like “allow anyone to connect”
• Unified management of owned devices Temporarily not planned; feels easy to implement with external scripts
• Firewall. support ports filter. want support tag filter in feature
• Support socks proxy
