What are you trying to do?
Running Jabber (XMPP protocoll) on port 110?
Or running a Jabber-ICQ gateway on port 110?

I guess it's the first.
Have you any POP-server running on your machine in pirt 110? If so, you
can't run jabberd on that port to. In that case, uninstall the
POP-software.

If you try ejabberd, it can serve many virtual Jabber-servers on
different ports. It might work. Problems with ports under 1024 is that
they can only be opend by processes running as user root. And that is a
security risk. There are technics to go around that, but I don't know
if jabberd or ejabberd implements those.
