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. _______________________________________________ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "freebsd-questions-unsubscr...@freebsd.org"
