Mailbox unknow with multi domains

[Guillaume LUDWIG]

Hi,

one of my mail server crashed, so I managed to replaced it with my "personal" 
Kolab (2.2.0) server at home.

This server runs on Ubuntu.

I use it for my mails at gmli.fr, and it works perfectly. My other mail server 
was for cfait.fr. 

In the "settings" tab in the web admin section of Kolab, I've added the domain 
"cfait.fr" and clicked Add, then restarting Kolab.

I've made an user named gml at cfait.fr, for primary email address i've entered 
'gml' and selected "cfait.fr" in the select box. 

The user was correctly added, and I can sent mails with it. But when I try to 
send mails to this account with another one (using gmail, or using an account 
from gmli.fr), I get that :


Mar 31 20:27:29 eeebox <info> postfix/pipe[28196]: 6CB203FE1: 
to=<gml at cfait.fr>, relay=kolabmailboxfilter, delay=0.33, 
delays=0.06/0.01/0/0.26, dsn=5.3.0, status=bounced (service unavailable. 
Command output: Failed to set recipient: Mailbox unknown.  Either there is no 
mailbox associated with this name or you do not have authorization to see it. 
5.1.1 User unknown, code=550, original code 550)   

Note that i can't add a folder in Horde (for example a trash folder, it says 
permission denied).


Could someone help me ?

Regards,
Guillaume
