that could occur when
a. student machines are botted (for institutions not blocking outbound port 25)
b. student and alumni accounts are compromised by phishers

(both of these just for the purposes of sending spam from well connected, reputable institutions.)

and then consumers really do complain...

i'm told (not just by yahoo insiders) that the forms at

postmaster.yahoo.com

actually do work, eventually.

Christ .. Yahoo did say "complaints".  And it can take a very low
level of complaints before a block goes into place - especially for
low volume (corporate etc) mailservers.

I don't think this is Yahoo reacting to spam complaints because a large number of sites (many universities, for instance) are being affected by
this problem at the same time.
