Does anyone know how to set up virtual domains on my redhat box?
i.e. more than one domain, lets say 4 all aliased to the same machine.
Do i just alias them all to my primary domain or IP number or something?

Or has it nothing to with aliasing?

The purpose of my experiment is writing mail filter software. Hence, i need to set up a few domains from which i can then test out my filter files on.

Apache will not be used in this set up, only an MTA [exim].



Cheers in advance

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

Basically virtual domains are several domains pointing to the same ip address. Just set up a root domain (say donothing.org) and add several A or CNAME records to it with the same ip. Example:
As you can see www, mail, april, cc, stats all point to the same ipaddress.
