This seems like a good solution.  We would have to make changes to
pathalias to either indicate that an entry is the ONLY entry to be
used or place the changes in a files that would be read last and
modify pathalias to only use the data from the LAST entry found (as
I understand it, pathalias allows multiple entries for a site and
uses all of them).

We could then have an additional newsgroup called "mod.map.updates" or
something similar that would contain the updates and corrections to the
maps.  This should give us a much more current map and correct at least
some of the mail problems that are current occuring.
