There are a number of servers in Brazil which are totally broken. They are running with outdated versions of the network tables, which cannot be updated either for technical reasons (not enough disk space) or because of an administrative error when configuring the server. The people in charge do not answer mail. The best advice I can offer is to relocate the lists to another server if you have the misfortune of being hosted on one of these servers. Note that there are a number of servers in Brazil which work just fine :-) Eric
