New for IMail Server 2006.23

Features and Defect Fixes:


Web Client



Product Description

IMail Server is an Internet standards based mail server system for Microsoft Windows 2000 and Microsoft Windows 2003. IMail Server includes powerful antispam and antivirus management tools, a new Web-based administrator and client, and implements a series of programs that run as services including:

IMail also provides features such as a List server for creating and managing mailing lists and a mail to pager/beeper feature that lets you set up aliases on the IMail Server that forward mail from a mail client to preconfigured pager or beeper address.

IMail Server Features

Optional Enhancements


Registry Checker - Regcheck.exe is run automatically during a repair or upgrade, and can also be run from the command line. Regcheck troubleshoots registry conflicts during upgrades and repairs.

Ipswitch IMail uses InstallShield® Wizard to install the IMail components on your computer. Use the on-screen instructions to select the installation features that set up the mail server to your preferences.

The installation program automatically configures Microsoft Internet Information Services (IIS) 5.0 or later and Microsoft® .NET Framework 2.0 or later. It also sets user permissions automatically; however, if you need to configure permissions manually, the following Default IMail Permissions and Configuration must be set on your mail server to make it fully functional or for administrators who do not want to use the default configuration, you can use the Non-default IMail Permissions and Configuration. If you need to configure IIS manually, see IIS Settings. For using IIS Virtual Directories, see Using IIS Virtual Directories.

Starting Web Admin and Web Client

After installation, you have the option to launch the IMail Web Admin automatically. If you choose not to launch IMail Web Admin automatically, in your browser address box, type the IP address or domain name of the IMail Web Server followed by the path where you installed ICS Web Admin.

For example:, then press ENTER. The Ipswitch Web Admin login page appears.


Click Start > Programs > Ipswitch IMail Server > IMail Server Administration. The Ipswitch Web Admin login page appears.

To launch the Web Client, in your browser address box, type the IP address or domain name of the IMail Web Server followed by the path where you installed ICS Web Client.

For example:, then press ENTER. The Ipswitch Web Client login page appears.

Web Messaging Notes for Upgraders

The Web Messaging templates have been redesigned and no longer support the Web template infrastructure implemented in previous versions of Web Messaging (included in IMail 8.2 and earlier). When you upgrade to IMail v9.0/ICS 2006 or later, the previous versions of the Web templates are not functional.

Web Calendaring Notes for Upgraders

There were no updates to the Web Calendaring templates in this release.

The Web Address for IMail Web Calendaring:
By default, the IMail Web Calendaring server is assigned a Web address that consists of the domain name of the IMail Server and a Web server port number. The default port number is 8484. For example, if your mail host has a name of, then the address is:

IMail users can start IMail Web Calendaring by entering the address in the browser's address field. If you are not running another Web server on the same host, you can set the port number to the normal HTTP (Web) server port of 80. In this case, users do not have to specify the port with the Web address. For example, users enter:

Important: Some firewalls may block the 8484 port, in which case you need to change the port number.

Secure Sockets Layer (SSL) Notes

The private key file is protected using a password specified in SSL Configuration Utility. This password is required for decoding the key file while loading the SSL server. This password is stored in the registry and automatically retrieved during the loading process of SSL Server. The registry path for IMail is usually SOFTWARE\Ipswitch\imail\ssl. The registry path must be correct; otherwise an error message is generated and the files will not be created.

Changing Web Client Default Directory (Redirect)

To set a redirect so Web Messaging users do not have to use \IClient in the URL for Web Messaging:

  1. Click Start > Programs > Administrative Tools > Internet Information Services. The IIS console opens.
  2. Right-click IClient (usually located under Web Site > Default Web Site).
  3. Select Properties. The IClient Properties dialog box opens.
  4. In the Execute Permissions list, click Scripts only.
  5. Copy the directory path in the Local Path box.
  6. Click OK.
  7. Right-click Default Web Site.
  8. Select Properties. The Default Web Site Properties dialog box opens.
  9. Click the Home Directory tab.
  10. Paste the directory path you copied from the IClient dialog box Local Path box into the Default Web Site Properties dialog box Local Path box


You can downgrade the IMail Server 2006.23 back to a previous version of 2006 or earlier ICS installation (v2.0, 2.0A, 2.01, or 2.02) without uninstalling as follows:

  1. Open the Registry Editor and locate the following key:
  2. Change the Version value to 2000000 (hex)
  3. Launch the installation file and proceed as normal.
  4. When asked if you would like to convert your LDAP database, select no.

Note: The IAdmin and IClient virtual directories and web files will still be on the computer.

Important: Mailbox sizes are corrupted after downgrading IMail 2006 to an earlier version (IMail 8.x). If you have quotas set up, they will fail. To correct this, delete the .uid and .xml files.

Important: When downgrading IMail Server 2006.23 to a previous Imail version, you need to delete the configuration.xml file from the top-level IMail folder


  1. Open the Add/Remove Programs applet in the Windows Control Panel.
  2. Select the IMail or ICS Edition you want to uninstall.

Removing IMail Server using the Add/Remove Programs applet does not delete the IMail directory or the subdirectories and files it contains. To remove these, you must delete them manually.
Everything is deleted in the Windows registry under HKEY_LOCAL_MACHINE\Software\Ipswitch\IMail (but the Ipswitch key is not removed).
Directories and files created by setup.exe are removed if they have not been modified. For example, if you have not added any users (and root never gets mail), the Users directory is removed. If these directories have been modified (i.e. the root or users accounts have received mail), you must remove them manually.
