Connection Refused

[Paul Franklin]

Greetings!
I have set up Kolab and am attempting to do a couple of things that
don't seem to want to happen.  The first is what I would think is the
easiest:  send a message from one Kolab user on this box to another on
the same box.  When I send a message, the sending computer gets no error
message.  Everything appears fine.  But then when I log in as the other
person, there is no mail.
The postfix log says that the connection is refused on 127.0.0.1.  In
the Privileged Networks box I have listed 127.0.0.0/8, 192.168.1.0/24.
Kolab is running on an Ubuntu 7.04 server.
Here are some lines from the postfix log:

May 20 17:52:07 ubuntufs <info> postfix/smtp[18009]: A94D51160269: 
to=<pdf at paulfranklin.org>, relay=none, delay=1210, status=deferred 
(connect to 127.0.0.1[127.0.0.1]: Connection refused)
May 20 17:52:07 ubuntufs <info> postfix/smtp[18008]: connect to 
127.0.0.1[127.0.0.1]: Connection refused (port 10024)
May 20 17:52:07 ubuntufs <info> postfix/smtp[18009]: connect to 
127.0.0.1[127.0.0.1]: Connection refused (port 10024)

Can anyone straighten me out here?  I'm not very proficient in this.

Your readers, who with me have never seen any signs of sunshine before 
noon, and seldom regard the astronomical part of the almanac, will be as 
much astonished as I was, when they hear of his rising so early; and 
especially when I assure them, that he gives light as soon as he rises.
--Benjamin Franklin, 1784
