kolab on sarge using debian package

[Fathi Boudra]

hi,

i have backported kolab package from sid to sarge and installed them. I can : 
* connect to webadmin
* send mail from the local kolab server
* login from a host using imapd

but when i try to send a mail from the host, it failed. My log returns :

Aug 22 16:50:54 localhost postfix/smtpd[2928]: connect from 
unknown[192.168.0.1]

Any clue, how i can resolve ?
