# This little perl program will take an internet address of the form
# foobar@some.place.domain and will print out where in the world that
# message originated from.  Its pretty dumb in that it just matches
# the `domain' part against a hard-coded list.  Also, I haven't
# checked the list for validity -- I picked it up from someplace. With
# the speed in which political boundaries are changing these days, no
# doubt there are some incorrect mappings.
