Thanks for hint, but what is bothering me is why sending to 
didtributionlist at domain.com bounces? As I see picture - postfix gets email 
for DL, then postfix asks ldap to extract emails of this DL and then postfix 
sends emails to all the members of the DL. After kolabmailboxfilter is 
responsible for delivering mails localy. In the kolab/issue825 (Bad error 
handling of kolabmailboxfilter) it is said, that the problem is that 
kolabmailboxfilter is failing for all the recipients of the DL if one 
delivery fails. I changed kolabmailboxfilter_destination_recipient_limit = 1 
in the postfix main.cf file and postfix is sending 1 message at a time to 
kolabmailboxfilter, so kolabmailboxfilter delivers email to DL members except 
for distributionlist at domain.com.

So my question is - why kolab wants to send email also to 
distributionlist at domain.com. I expect it to send email to all emails in DL, 
but not to DL email itself?

It seems to me, that postfix is misconfigured. It should not return DL email 
to the kolabmailboxfilter, but only emails of DL members.

Actually I was a qmail guy untill now and my experience with postfix is very 
limited. In qmail-ldap I create qmailuser with mail and 
mailForwardingAddress'es, set deliveryMode to nombox and it is working - all 
emails sent to mail are delivered to mailForwardingAddress and no mail are 
delivered to mail address. So I think postfix should also work in a similar 
way.
