Jabber server (jabberd 1.4) does not uplink to main jabber hubs
I've set up a Jabber server on my host (jabberd 1.4) and the server itself, seems to be working fine.
User registration works good, secured connections, and all.
But the server does not interconnect with the jabber hubs, obviously.
Since when I log in to my jabber server, all users I see, are those that are registered on my server, and that are online.
Usually I'd see all people, that are online, and that I have in my contact list, no matter what server they connected to.
Did anyone else had to deal with this problem?
Maybe it's just a configuration issue. If so, please give me a hint where I probably made my error.
