One of the things about working in a university environment is
top-level network policies are often set by a separate campus-wide
entity; sysadmins working on the department level often have no
control over this.  So the blacklisting decision may not be something
he has the power to change.

Also keep in mind that in a lot of university environments network
access is uncontrolled.  Where I work students can plug into any
network jack and have full access.  They do make an effort to react to
and shut down compromised machines, but I can see why blacklisting IPs
that aren't intended to have mail servers on them might seem like a
reasonable proactive measure.  There are blacklists that attempt to
contain all home cable and DSL IP blocks for exactly this reason.
