Universities are often major sources of spam. Spam is sent directly
from virus-infected student computers, and spam is also sent to students
at their university email address and then .forwarded on to the
student's outside (or post-university) email account - when the student
receives forwarded spam at their Yahoo account and clicks "this is spam"
the university is considered the "source" of the spam.
