It probably is that you are trying the send emails with 
the following from line:
  From: Mish <mailto:mish at kolabdomain.com>

The "mailto:" part looks fishy, can you check your outlook
email account settings? Also check the From: lines if you can
so see what is actually send.

Background:
kolabfilter.php checks that envelop and from: lines are matching 
when the result comes from kolabdomain.com.

You might see more in
/kolab/var/resmgr/resmgr.log

We are still refining kolabfilter.php, but you can switch it off, if you do
not want the protection or want to allow broken client configurations.
Check
/kolab/etc/resmgr/resmgr.conf
