Hi all,

(kolab 3.2, debian wheezy)

after setting up multidomain support in kolab 3.2 according to I have the following 

Assume we have the primary domain:
and two added:,

I can send emails to user at and user at but not to 
user at anymore.

The error is: 

Mar 24 22:27:14 kolab3 postfix/submission/smtpd[7208]: NOQUEUE: reject: RCPT 
from localhost[]: 550 5.1.1 <user at>: Recipient address 
rejected: User unknown in local recipient table; from=<user at> 
to=<user at> proto=ESMTP helo=<kolab3>

and in ldap access log I get:

conn=5 op=44 SRCH base="dc=datenkollektiv,dc=net" scope=2 filter="(&(|
(mail=user at at!
(nsUniqueId=d10b7401-b39311e3-943cf169-810dacce)))" attrs="mail alias 
[24/Mar/2014:21:36:21 +0100] conn=5 op=44 RESULT err=0 tag=101 nentries=0 
etime=0 notes=U

it's filterd with nsUniqueID - and this is obviously the reason that the entry 
is not found.

Searching with this ldap filter manually I also did not get any result. Without 
the nsUniqueID-Attribute the user is found.

Has anybody an explanation?

(Before setting up multidomain it was possible to send to
