I have used these docs a number of times (yes all of them) for CentOS-5 
with no apparent issues - Thanks guys - much appreciated from me.

I have just (8 months) set up a new CentOS-6 server using the same 
guides with few changes needed - I have just implemented virtual mail 
boxes on this for multiple domains, all working but no admin interface - 
i.e. need to edit config files to add users etc. Still looking into this 
bit to see if there is an option that is not full of security holes, 
thus far I would not expose the admin interfaces to the internet, i.e. 
only make them internally accessible.
