I have an OpenBSD server, and I would like to configure a corporate/personal domain name to be Jabber / XMPP enabled, and to automatically proxy (forward/alias) messages between some set of local accounts and a given gmail.com Google Talk account.
Requirements, all must be satisfied:
no new accounts at Google; has to work with an existing gmail.com Google Talk account
no new clients, has to be able to use the corporate domain through existing gmail interfaces
no local accounts to log into, an alias-only solution is needed
In email terms, I'm looking for a
virtusertable (or some such) with Sender Rewrite Scheme.
In other words, it would sound like I need to setup some kind of an XMPP-to-XMPP transport / gateway on my server. There surely must be such a thing, as there are many other kinds of Jabber transports / gateways available, between XMPP and non-XMPP networks; I see my case as similar to that.
(Google Apps does not fit, because it requires new and separate accounts.)
