New submission from Bernhard Reiter <bernhard at intevation.de>:

User reports:     
    
Emails are send to a group of user and postfix expands    
it (=similar to distribution lists)    
With high numbers of recipients this does not work anymore.   
   
  service unavailable. Command output: Failed to set  
     recipient, general Error: (kolabmailtrasnsport.php):

     Invalid response code received from server, code 550 
 
What could be the problem? 
We should retest this with a high number of users in a distribution list.
