Why can the Campus UMail server just delete this stuff for my utah.edu Email account?
In general, OIT only blocks email when there is great probability that the incoming message is harmful to the University’s computing and networking systems. Viruses and worms fall into this category. If OIT were to block messages more aggressively, it is possible that legitimate messages would be filtered out. It’s important to recognize that the problem of unsolicited commercial email has no perfect solution, be it technological or legal. The University and OIT must take actions that serve the interests of faculty, staff, and students, while preserving the openness that is essential for an academic institution. You should regularly inspect your spam folder to identify any messages that you don’t consider spam.
