Radio, TV, and newspaper are each a better analogy. Postal service is more akin to the infrastructure of radio/TV/newspaper (which differs, and is rather not one but various, e.g. cable, FM, and paperboys). The analogy with Internet would be transit providers. The undersea cables between US and EU, for example. These are heavily logged, e.g. by UK. Imagine all your post be scanned, that'd be GDR-esque.
