The .NET web interface runs on port 80, or what ever port you have IIS listening to. Here is what I did:
1. I created a new web site in IIS. I set the Host Headers to the domains that I wanted to use webmail for. By doing it this way, I have one install of the web interface that can service several domains.
2. I ran the install program for the web interface and instead of selecting the "Default Web Site" I selected the newly created site. (I named it ArGomail).
3. I placed a default.aspx file in the root of the web site. The contents of this file will redirect the user to the \webmail folder where the web interface resides. So if a user types webmail.mysite.com it will redirect them to webmail.mysite.com/webmail. I will attach my default.aspx to this message. It is Zipped up so not to cause any issues with the web site.
Notes: When creating the folder for the new site, make sure that IUser_[Computer Name] Account and Network Service account have "Read & Execute", "List Folder Contents" and "Read Permissions". I throw the Administrator account with Full Control. In IIS on the Home Directory Tab, click the "Create" Button to create a new application. In the Execute Permission drop down, set this to "Script Only". For application pool, you can use the default, or create your own application pool.
For me, as a rule of thumb, I never use the default web site for anything, for security purposes. As a matter of fact that site is disabled on my server.
Currently there are no theme packs like there were for the pro version. The interface uses "Themes" so you can customize it. Information on Themes can be found here at http://www.argosoft.com/rootpages/M...hemes.aspx
I have not yet had the time to play around with the themes yet, so I do not know how easy/hard it is to customize.
