What's New in IMail Server 11

IMail Mobile Synchronization

Users now have the capability to synchronize their mobile devices with their web client information to include e-mail, contacts and calendar events. Users can maintain their contacts and calendar appointments from either their computer or mobile device, and remain synchronized.

Outlook synchronization is also capable, but requires installing the WorkgroupShare Client. This enables synchronizing e-mail, contacts, calendars, notes, and tasks between their web client, Outlook and their mobile devices.

Default Mobile Synchronization Settings

The new Console Administrator has the bulk edit user capability, and can turn on this feature by going to the Domain > User List page, select all users and checking the Enable Mobile Synchronization.

Warning: It is recommended that Mobile Synchronization is not turned on for all users simultaneously, as the initial mobile download will put a high stress on your IMail system. See System Requirements for mobile user recommendations.

See the IMail Administration Help > System Settings for more details on enabling this feature. Also available for mobile device owners is the Mobile Sync White Paper.

Product Update

To allow integration for all users to receive the greatest benefit for mobile synchronization, Ipswitch has modified the Product Offerings. WorkgroupShare previously only offered with IMail Premium has the component necessary to allow mobile synchronization with Outlook to include e-mail, contacts, calendars, tasks and notes. WorkgroupShare and Ipswitch Instant Messaging has been integrated into IMail Server Plus and IMail Server, obsoleting IMail Plus, and leaving IMail Server and IMail Premium. See new Table of IMail Product Features.

New IP Reputation by Commtouch (IMail Server Premium)

Ipswitch has integrated Commtouch's GlobalView™ Mail Reputation services into IMail Server Premium v11. By default upon installation the new IMailCommtouchIpRep service will be enabled (a wrapper for Commtouch's ctIPd™ daemon) and set to only logging. This default will need to be updated by your System Administrator to enable the full capability of Commtouch's IP Reputation daemon.

The Commtouch GlobalView Mail Reputation daemon (ctIPd™) is an embedded reputation engine with a small footprint. It is responsible for maintaining communication with the Commtouch Datacenter. ctIPd™ delivers reputation data to messaging, security and networking devices, providing an added layer of protection while saving valuable resources by enabling the messaging network to analyze and process requests before message reach the network. These querying devices post queries to ctIPd™ over HTTP, UDP, or RBL/RBL+ protocol requesting reputation data on source IP addresses attempting to establish SMTP sessions for sending messages to recipients.

See the Administration Help at Antispam > Premium Antispam, and Services > Antispam for more information.

IMail Console Administrator

Back by popular demand, the IMail Console Administration application has been rewritten with full functionality for handling all System Administration functions.

Note: WorkgroupShare (Collaboration) and Instant Messaging have been omitted, as separate Console applications already exist for both applications. Look for them at Start > Programs > Ipswitch IMail Server.

The IMail Console Administrator has the following new functionality:

New Web Administrator

The Web Administrator originally written using classic ASP has been rewritten to use ASP.Net 2.0 to provide better performance.

Note: Instant Messaging has been omitted from the Web Administration application, as a separate Console application is available. Look for it at Start > Programs > Ipswitch IMail Server > Instant Messaging Server

Twelve months Support and updates







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.

Tip: Before installing on Microsoft Windows 2008 Server, be sure IIS 7 has "Metabase Compatability" enabled. See also Installing IMail Server on Microsoft® Windows 2008.

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 the 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 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 2006 and later, the previous versions of the Web templates are not functional.

Note: Port 8383 is no longer the default port for Web Messaging, as IIS by default uses port 80.

Secure Sockets Layer (SSL version 3) 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.


Downgrading from v11.02

Customers using External user databases will have to manually reverse the Maximum Mailbox Size column type back to "integer".

Warning: Any updates made to Maximum Mailbox Size that exceed the 2GB mailbox size will need to be corrected to their original values to avoid truncation.

IMail Server Premium Downgrading

Warning: Downgrading from IMail Server Premium v11 or later to v10.01 or earlier will cause the Premium Antispam Services to stop working.

Read the KB article for details on downgrading to IMail Server v10, or v10.01:

Once a user has installed and been licensed with Commtouch Premium services, he/she can no longer be downgraded to a previous version unless the Mail-Filter license has been backed up and saved to a path outside of the Ipswitch folder.

IMail Server Standalone Downgrading

Important: Downgrading from IMail Server v11 or later to IMail Server v10.02 or earlier will remove Ipswitch Instant Messaging and WorkgroupShare.

To downgrade the IMail Server back to a previous version without uninstalling:

  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 11 or later 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 11 Server or later 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 Edition you want to un-install.

• 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.
