I'd hope/assume that any Computer Science students would be able to do this, but most Biology/Education/English/Art students probably couldn't.

I mean, anyone smart enough to attend university could probably figure it out if they really wanted to, but there are hundreds of other useful things that they could learn too. There are only so many hours in the day, and given that most students don't get that many emails, I can hardly blame them for not wanting to prioritize learning how to filter emails.

(I personally have over a hundred lines of Sieve filters, but I'm definitely not a typical student)
