what i want to do is; Have four domains, e.g
a.domain.org
b.domain.org
c.domain.org
d.domain.org
This will not be live on the net, it's purely for experimental purposes.
Then i want numerous email addresses, e.g
john@a.domain.org
jumpupndown@b.dowmain.org
etc etc
this will all be aliased to one mail box which i have already on my machine.
I am using Exim to do the mail transfer which can handle the aliasing for the mail boxes no probs, i was just a little perplexed as to what zone files to create, what to stick in them, do i use CNAME for the other domains or do they have their own zone file...
i think you've already answered that one but im still not exactly clear on what it is i need. (relative newbie here <-)
any more help much appreciated
