First xmpp message. Does server decide if encryption is used?

Hi, welcome!

Which layer of encryption?

TLS encryption is always used, obviously the client has to use it, and the server will reject clients that don't

End-to-end encryption is up to the client, not the server. The point of end-to-end encryption is to protect message contents when the server cannot be trusted. In such a case, depending on the server to decide would be fundamentally problematic :)

Ok. Thanks. I'm using Conversations on Android and it says: send unencrypted message. So if I dm some one it will use end to end. I have OMEMO encryption on in settings.

Public chats such as this one generally do not support end-to-end encryption, for many reasons

e.g. public chats generally don't reveal the real XMPP addresses of the participants, which makes it harder to retrieve and verify their keys. This can be solved, but then the security gained by doing end-to-end encryption in a public chat is negligible.

So it just adds complexity and overhead for little (or even negative) gain

Does it take a lot of resources to host a xmpp server? (For under 10 people.) I want to test it my unraid server.

No, it doesn't take much at all. A good starter server is Snikket (which I work on): https://snikket.org/faq/#q-what-are-the-system-requirements

I'd like to have a ready-made Unraid template for Snikket one day. I'm not an Unraid user otherwise, so I don't know how easy/hard it is to set up without one.

I'm a noob but I have installed a few tings from dockerhub with out problems. Maybe luck.

https://snikket.org/service/quickstart/ - good luck :)

Thanks

Will you start charging money for selfhosted servers?

no

Self-hosted servers are entirely under your control, there's no way to charge for them (all the software is open-source and freely available). Donations are always appreciated though 🙂

@MattJ, Does snikket server support third-party xmpp clients? Does it supports voice calls in Conversation?

Shura, https://snikket.org/faq/#q-can-i-use-non-snikket-apps-to-connect-to-a-snikket-server

Conversations is generally fine - the Snikket Android app is based on it ✏

Thank you. Now I have prosody server and I want change it to snikket
