Is it possible to have root sent emails via kolab?

[Richard Bos]

Hi,

is it possible to sent email from root, via the kolab server?  The emails are 
sent for information after a cronjob has run for example.  The user root has 
not been configured in the kolab system, so it is correct that kolab 
complains.  Anyway it should still be possible that root sent its emails, 
isn't it?

I now get:
===========

This is the mail system at host mail.example.com.

I'm sorry to have to inform you that your message could not
be delivered to one or more recipients. It's attached below.

For further assistance, please send mail to postmaster.

If you do so, please include this problem report. You can
delete your own text from the attached returned message.

                   The mail system

<user at example.com> (expanded from <cron at example.com>): permission
    denied. Command output: Invalid From: header. root at example.com
    (root) looks like a forged sender
