If you are using BIS, which I assume that you are, email does not sync.
What you can do is set it up to delete from the server when you delete from the BB. If the email has downloaded to your PC email client, then it won't delete there.
If it has been downloaded to the PC client, then it will delete and not get to the PC.
There isn't a real clean/easy/foolproof way to do what you want right now.
