Undelivered mail returned to sender

[Ger Apeldoorn]

Hi,

I've got a little problem with amavis/clam on my kolab server. 

When a virus is reported, it tries to send a notification to 
virusalert at argoss.nl but I get a error notification instead:

Final-Recipient: rfc822; virusalert at argoss.nl
Action: failed
Status: 5.0.0
Diagnostic-Code: X-Postfix; service unavailable. Command output: Failed to set
    recipient: Invalid response code received from server, code 550

If I send an email manually to the same address; it works fine. The mentioned 
address is a distribution list generated by kolab.

Any help very much appreciated!

Ger.
