I got following message: There is no OLD list on this server. Try sending a "LIST" command to get a description of all the lists available from [log in to unmask] There is no BACKUP list on this server. Try sending a "LIST" command to get a description of all the lists available from [log in to unmask] the LIST command confirmed all lists exist. Any idea? Regards, Eric
