It depends on which device you are asking about. Your profile lists both a 9800 and a Z10. In both cases, there is no removal from the server upon delivery to the device. But after that, they function differently.
For the 9800, there are several conditions that must be met to delete from the server when you delete on the device:
With all of that, it will do as you instruct based on how you have configured it, the capability of your server, and how you use it. Note carefully that, if your server is not capable, then the settings you configure and the way you use it will be irrelevant.
On the Z10, the device and the server are intended to be replicas of each other. What you do on one will act on the other. There is no setting to override it and allow you to delete on the Handheld only. The workaround is to move to a folder rather than delete.
