Hello,

I have a high-level overview of what is happening in our internet servers, b
ut am unable to understand exactly what needs to happen on a more technical 
level. This was all setup a long time ago and is no longer fully supported. 
I am looking for assistance in creating a more technical workflow for my sce
nario. I will explain the best I can the details that I know from a high-lev
el, if I need to provide further information please let me know.

I have a web server that is behind a firewall and is inacessible to the worl
d. All the web pages get deployed here. There is also an IIS server using IS
API_Rewrite from Helicon to redirect web traffic to the web server. What exa
ctly is happening here?

Now as new sites are deployed on the web server we also get a domain, usuall
y from go daddy, and redirect it to our ISAPI_Rewrite server. How exactly do
es a domain name get redirected to our server? Additionally, how does this r
elate to how the web pages from the internal server being displayed to the w
orld?

In the future we may want to use existing domain's that have websites on the
m, how do we setup this existing domain so that it can also work for our new
 sites? For example if we deploy a website on our server, how could we use t
he webservertalk domain to also point to our server without hendering the we
bservertalk site itself?

There are also scenarios where bulk email needs to be sent. We have a sepera
te server for this which is hosted at Godaddy, the software we use for bulk 
email is Group Mail. In our first situation we used one domain for the email
s, and another one for the website we were promoting. Is it possible to use 
the same domain for both? This may be a similar situation to the question re
garing 1 domain pointing to 2 web servers.

I think that about explains the situation, here is a small recap:

We have 3 servers: Web Server behind firewall with no Internet access. Rewri
te Server using Helicon/ISAPI_Rewrite. And a Email Server for sending Bulk E
mail. In some situations we will use a new domain for the site, in others we
 may want to use an existing organizations website such as webservertalk. We
 would like to be able to use the same domain for sending email as the websi
te we are promoting.
