Mail forwarding, while convenient when you want to send all your mail to a gmail, yahoo or other free type or external account, is not allowed in the Netsonic shared hosting environment. The receiving mail servers see the originating server as your hosting server here. This means any spam sent to your mail box that is forwarded looks to have originated from our servers and thus causes significant problems for all users on the server when blocks and blacklisting are employed on the receiving end. It is therefore not allowed in the shared hosting environment.
