If you'd just block out the extensions and I were a student in your faculty and wanted to send an MP3 or something, then I'd just goof a bit more and rename a .mp3 to a .txt, just because I can get around that. That's what I think (most) students do if they're clever enough. Of course blocking extensions is cheap in CPU/mem resources but IMHO it's not the way to go. Inspecting the attachments checking for filetypes to block is more intensive but also much much harder to omit. Of course, you can still block these extensions... :-)
