[cobalt-users] Backup/Secondary Server

[timothy <timothy@xxxxxxxxxxxxxxxxxxxx>]

We have 2 cobalt RaQ4r. We want to make one of them as a secondary DNS and 
backup Email server. How can we config the seconadary cobalt as a 
seconadary DNS so that it will automatically update its DNS record with the 
primary DNS server. Also, we would like to config it as a backup email 
server so that if the primary server fail, the email will automatically 
sent to the secondary server. THX
