A German court has ruled that a university acted illegally by blocking incoming emails from a former employee from reaching addresses within the institution. It's reasoning on the issue was that email is private and therefore the university did not have the right to filter it based on content, unless related to combating a viral threat.
The Register is wondering if they have thereby unintentionally banned spam blocking too, as that is generally done by applying filtering rules to message content. Surely it's more likely that spam-blockers will just be offered as services to which users have to consent, thus getting around any possible privacy issues.
