I run a few websites for others on the same server I run Mail Server.NET.  Previously with Mail Server Pro, I had a custom log-in page under each domain that logged each user into MS Pro's webmail with their domain already entered.  This gave the appearance each domain had their own webmail server as each user always viewed their own www.*mydomain*.com/mail in the address bar of their browser.

Right now I have MS .NET webmail interface installed under my personal domain for testing purposes.  Is it possible to install the webmail client under each doimain on the server or is my only option to have every user access webmail under the same single domain?

I have not done a lot of work with this web interface since I have a small user base and customization of the web interface is not necessary.  Off the top of my head I can think of two different ways to accomplish this.

Install the web interface once, then use IIS Host headers to set different host names (IIS Manager -> Web Sites -> Your Web Site Name -> Right Click -> Properties ->  Web Site Identification -> Advanced). Note: Instructions are for IIS6 on W2K3, newer or older version of IIS may be different.  See image at right.

The second method would be to install the web mail on each web site, but to me that is a bigger maintenance issue when you need to upgrade the web interface.

I also recall the new version of the web interface supporting themes. Please see the following ArGoSoft Document on the subject:
