I have downloaded and installed zimbra iso file in VirtualBox.  

The Installation was flawless.

But I could not figure out following...

As per the info given on turnkey site, I am supposed to fill some values based on my setting..

Example  :

mail                222.222.222.222             A
example.com.        mail.example.com            MX
example.com.  	    v=spf1 mx ~all              TXT

Now where these values have to be filled ?  ( in zimbra installation or at my domain provider )

Can I configure co.cc domain with this appliance ?  If yes, what is the procedure.

A step by step tutorial will be very useful for this great appliance.

Thanks in advance...

PS :  Similar question was asked on Zimbra forum but I was told that Zimbra does not support unless it is downloaded from their site.  I was told that I should post all the question on Turnkey forum only.
