I have apache working correctly (I think) I'm having trouble knowing where/how to setup Virtual DNS - I want to setup CNAME for all of my e-mail users to match the domain name that they own - but i want to server this up off of 1 linux box using one IP address.  I have the domain names routiong correctly - now i want them to pop there e-mail down using there own domain name.  Where do i add these CNAME records and will i need seperate MX records for each domain name ??

Hi,

First of all you can easily have several services (mail, dns, web, ftp, and so on..) wherever you want on only one computer and/or dispatched on several ones.

In this case you just have to set up as many domain.com.dns zones as you manage domain names.

In my example :

Let master.com be your master domain
and secondary.com your second one.

master.com zone is defined as :

@     NS ...
@     NS ...
mail  IN A 254.254.254.254 (your IP)

secondary.com is defined as :

@     NS ...
@     NS ...
@     IN MX 10 mail.master.com
pop   IN CNAME mail.master.com

Don't forget to set up your mail server with a (Qmail) /var/qmail/control/rcpthost filled with full qualified domain names list to activate mail handling.

From your clients side it will appear as pop.secondary.com computer host.

Hope it helps. Sorry for my english.. ;-)
