I have OS X Server 10.6.5 running on a new Mac Mini (server model), serving several functions among which is iChat Server (iChat and Pidgin on Windows as clients). In the iChat log in Server Admin, I kept seeing entries about connecting to proxy.eu.jabber.org. It's for our office network and I wasn't excited about external access to it, so I disabled server-to-server XMPP federation and now the connections just time out. But why is it doing that in the first place?
Sample log entry:
(datetime) (servername)jabberd/resolver[portnum]: [xmpp-server._tcp.proxy.eu.jabber.org resolved to 18.104.22.168:5269 (300 seconds to live)
sending dialback auth request for route '(full server hostname)/proxy.eu.jabber.org'
A couple minutes later, it comes back with:
dialback for outgoing route '(full server hostname)/proxy.eu.jabber.org' timed out
