Distribution lists issue

[JP Viljoen]

Hi

I've got an inherited kolab setup, which I'm learning as I go along, and currently I'm having an issue where distribution list addresses which get set up 
do not seem to work. I created a list named testlist, and when sending mail to it, I get the following output in the maillogs:

Oct 17 14:50:45 10.0.0.2 postfix/pipe[26399]: B99131F0017: to=<testlist at domain.tld>, relay=kolabfilter, delay=0.14, delays=0.03/0/0/0.1, 
dsn=2.0.0, status=sent (delivered via kolabfilter service)
Oct 17 14:50:47 10.0.0.2 postfix/smtp[3706]: CA0E51F0029: to=<testlist at domain.tld>, relay=127.0.0.1[127.0.0.1]:10024, delay=1.3, 
delays=0.06/0/0/1.3, dsn=2.6.0, status=sent (250 2.6.0 Ok, id=03348-07, from MTA([127.0.0.1]:10026): 250 2.0.0 Ok: queued as 
1410F1F0017)
Oct 17 14:50:47 10.0.0.2 postfix/pipe[3341]: 1410F1F0017: to=<testlist at domain.tld>, relay=kolabmailboxfilter, delay=0.12, 
delays=0.06/0/0/0.06, 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 )

I have also tried restarting the kolab service (just in case, since I have no idea how the kolab architecture works for refreshing configuration 
information or such), and still get the same output after it. Any help or information would be appreciated. Some more information, if needed: gentoo 
based server, with the following packages and versions:
