list messages bouncing due to no reverse dns!

The netblock of IP addresses got hijacked by someone bad, and the 
nameserver entries were changed without permission from the owners. As 
soon as they can get ownership back, they will correct the nameserver 
records and everything will return to normal.

In the mean time, sorry, but there's nothing much I can do about this 
except suspend normal processing of list-bounce error messages, which I 
have done. The only other option would be to move the entire list to 
somewhere else, which is a big job just because of a temporary outage at 
a time of year when everything would be pretty quiet anyway.

Hope that's okay with all of you.
