Only add servers to the Kolab Hosts, if they are Kolab Slave Servers.
To send email without SMTP auth, adding the servers to the trusted networks
should be sufficient.

Chech the logs about why the emails did not arrive,
note that Kolab usually wants to have correct envelope and header froms.
Note that this is different to the reply-to which can be set to anything.
If you feel this could be the problem: Try to disable the header from checks
to see if this makes a difference.
