For various reasons, we are trying to setup a subdomain for IM. At the same time, we’d like this to be transparent to the outside world. For example, if I’m email@example.com, we’d like for others to be able to add/see me as firstname.lastname@example.org.
As far as I’m aware, currently whatever doesn’t match the IM domain is treated as a remote user. So here come the questions: is it possible to set up Openfire to do what we want? If not, is it possible to patch Openfire into doing that? Would that go against RFCs?
