This means that OL2000 tries to send mail as an unauthenticated user and 
Kolab / Postfix denies this because the sending IP is not trusted. (Could be 
a spammer)

Yes! Please don't use the OL "secure" password option. Please also remember 
that you must use the full email address (including the domain) as the 
username if you are using a genuine Kolab server but not the Mandrake server.

Connect from the OL2000 using IE to the Kolab Server. If you did not replace 
the self-signed certificate you must import this certificate in IE.

After you did this successfull (IE shows green check marks). You can connect 
from OL2K using TLS.
