Then it's not much of a DPI product they're using. Since DPI should not care about ports, as it is looking at every packet regardless of the port and determines what the protocol is by the packet headers and deeper. It should never care about the port, since you can run anything on any port.

Yes but these Ellacoya boxes they're using are capable of much more than DPI even though it is their main function. The main reason Bell configured it this way I think is because Bell uses port 995 for SSL over pop3. Not only does it do port filtering, they can use it to identify subscribers, measure usage etc.
