For the mailing list, either one should work fine.  For filtering on
a news server itself, using the Path site filter is generally easier.
So, if any of you are using a news server that does not honor cancels
and you are still seeing the reposts, you should ask your news admin
to drop all the reposts by filtering on the "resurrector" pseudo site.
