Setting "Confidential=Service" and then including "Service=*.ua.edu"
 will work.  And if you want to add other patterns, just list them on
 the Service= line separated by commas or add multiple Service= lines.
 So the lines,
 
 * Confidential=Service
 * Service=*.ua.edu,ua1vm
 
 might be a good choice in this case.  People that try to subscribe
 from other hosts/domains will receive the following response.
