That's exactly it, except each of them is not an XMPP network but just a single domain (there's only a single authority, so it doesn't make a lot of sense to talk of network). XMPP works exactly like SMTP in this regard: you can send a mail from a@gmail.com to b@fastmail.com just like you can (could, at least) send an XMPP message from c@duckgo.com to d@facebook.com
- pmlnr 11y agoWas this ever implemented anywhere like this? XMPP can do anything in theory, I understand, but had this ever worked? How bad was spam in this case?
- detaro 11y agoBasically all public XMPP/Jabber servers implement this, and it is fairly easy to set up (multiple of my contacts run their private servers). Spam has never been an issue for me.
- Macha 11y agoGoogle used to implement this, DDG still implements this, most small->medium XMPP servers still implement this. For a while, Facebook was the odd one out for not supporting it. Spam was less of a problem than e.g. spam on AIM. There's the fact that it's not any harder to sign up for AIM than a XMPP network, it's not popular enough and the audience too tech-savvy for spammers to bother, and if a specific host was a bad apple it's easy to BL them.
- rakoo 11y agoThis part is actually the one that is in the core of XMPP, so it doesn't work in theory, it just works everywhere (as long as administrators have allowed federation, of course).
