Just wanted to point out that a customer can create a forwarder starting with a plus + symbol but the forwarder cannot be deleted. If you try and delete it, you get the correct response that it has been successfully deleted but it remains in the list and in the valiases file. Server is on R17853 I should submit a bug report but im far too lazy to sign up for bugzilla. I dont know why anyone would want to create a forwarder beginning with a + anyway. In this case I just deleted the entry from the valiases file.
