[Operators] transitive federations?
Hi, Are XMPP federation transitive? In other words, if A federates with B, and B federates with C, can A send traffic to C through B? I can't find anything in the RFCs, XEPs, or vendor docs that permit this kind of transitive federation, but I'm not yet convinced that I've read everything that there is to read. Thanks!

No, they cannot. XMPP server-to-server traffic always flows directly from one domain to another. Regards, Matthew

Relaying is not supported. This isn't Internet Relay chat :-) I can't find anything in the RFCs, XEPs, or vendor docs that permit this kind of transitive federation, but I'm not yet convinced that I've read everything that there is to read. http://tools.ietf.org/html/rfc6120#section-2.5 Note that people from A can still talk to people from C in a MUC room hosted on B for example. However, that rewrites addresses.

Re: [Operators] transitive federations?
Out of curiosity, do you have a specific need for relaying or transitive federations? In general, if domain A is openly federated, it should be able to communicate directly with other domains such as B, C, D, E, ... without prior administrative configuration. To maximize the likelihood that other domains will communicate directly with domain A, A may want to follow a few best practices, such as: * have DNS SRV records, * enable encryption, * have TLS/SSL certs for each server issued from a recognized CA, and * have TLSA (DANE) records in a DNSSEC-secured zone. (in case other domain operators choose to not trust your selected CA but may instead trust DANE for cert validation...) Anyone else have tips? - David On August 19, 2014 12:48:41 PM EDT, Hiers, David david.hi...@adp.com wrote: Thanks for the responses!
