You don't need it all....
If you not have callrecoder it's just skip it, it's not a problem... I mean if you use background auto-changer - it have refresh command, just try to see sometimes if you have any problem with mail updates.
If you not use background auto-changer, but sometimes use refresh commands like in your previous post, just continue use your script or instead this, use my N9 Qrefresh button (it have all this commands in option F) and try to see if you will get any problem with mail app.
Thanks
