Hi Gregor,

Hopefully, I have not misunderstood your requirement. Assuming your  
server is a Unix or Linux box, I would like to suggest the following:

Use imapsync to copy all folders to mboxes for all users. Keep the  
mbox files in each user's directory and they can access it without  
having to do anything.

In one case, I used imapsync to convert mbox files to maildir.

HTH,

Vijay
