control.ctl. 

I recommend adding:

newgroup:group-admin at isc.org:*:drop
newgroup:tale@*uu.net:*:drop
rmgroup:group-admin at isc.org:*:drop
rmgroup:tale@*uu.net:*:drop

This should be immediately after the two lines that set the default
for newgroup and rmgroup to "*:*:mail".

In fact, I think I will add that to CURRENT/samples/control.ctl right
now.  It does have a commented out "log" for things *not* from
group-admin at isc.org, but I think it should just drop the bogus ones.
