There are two ways of implementing multiple domains on a mail server. I'll
illustrate with how you would set up and

One is a "quick dirty fix" - that is you alias additional domains to the
first one. This means that you have to give all users a different
pop-account name. For example: -> ->
Anyone logging into the mail server will discover that it is run by

The second is to use a second IP address so that from outside, no-one can
tell that the two domains are running on the same machine. In this case: -> ->

Personally, I feel that the latter is "Mutiple domain support". Anything
less is a scam.

NTMail provides the "Quick dirty fix" (we call it a redirection rather than
multiple domain support) just like most other mail servers our of the box.

If you want real virtual domains - then you need NTDomain. As far as we are
aware, we are the only mail server product for WindowsNT that supplies real
virtual servers in this way.

Many customers use the first method to alias domain names - some with over
500 domains aliased to one. Others use the second method. It all depends
upon what you preceive as the best solution for the way you wish to work.

I hope this clears up the pricing method and what the difference between the
two versions are.
