Hi Michael, OK it just takes some time until it activates (even after 
restarting lighttpd). So now I can logg per device and that client which 
made such a slow impression stops syncing after ~8GB and the last 
message in the log reads:

2015-09-10T09:53:10+02:00 INFO: [2036] Maximum memory usage for 
ActiveSync request: 64225280 bytes.

This Email-Account has more than 50 folders and subfolders. So should I 
raise the maximum Memory for ActiveSync requests? If yes, where could I 
do so? Kind regards, Jens.
