I was wondering if the XMPP standard defines support for temporary/disappearing messages, and apparently it does via XEP-0079. But Prosody, which is the server I run, doesn’t support it. Anyone know why this is, or if it’s on the roadmap?
Seems like a rather obscure feature that can not be enforced client side anyways. What do you want it for?
It’s not an obscure feature, it’s very standard amongst the non-federated chat messengers. I want it because I don’t want to worry about chat logs on other people’s machines.
Well as I said, impossible to do. Anyone could just run a client that ignores these suggestions (as most clients probably will given the obscurity of that XEP).
Edit: also what you ask for isn’t the purpose of that XEP:
Extensible Messaging and Presence Protocol (XMPP) is a communication protocol for message-oriented middleware based on XML. Learn more about it here.
