RE: [cobalt-users] Setting up Qube3 as a secondary mail server

["Bagus" <baguswinarko@xxxxxxxxxxxxxx>]

Thanks Ed,

I did that but my further question :
Do I have to put CNAME on my DNS?

mail1    IN    A    10.1.1.1
mail2    IN    A    10.1.1.2

mail    IN    CNAME    mail1
        IN    CNAME    mail2

something like this, so my client will automaticaly recieve mail from 
secondary when primary goes down?
Do I have to syncronize all of my user?

Apreciate to U Ed & List
