Commtouch® Zero-Hour Virus Outbreak Protection provides a complementary shield to conventional AV technology, protecting in the earliest moments of malware outbreaks, and right through as each new variant emerges.

Server-side polymorphic malware has become impossible for traditional AV engines to block, since there are typically thousands of distinct variants, and malware distributors often release hundreds of new variants per hour.

Commtouch® Zero-Hour Virus Outbreak Protection provides a complementary shield to conventional AV technology, protecting in the earliest moments of malware outbreaks, and right through as each new variant emerges.

Note: IMail Server was modified to handle the Commtouch scan at the SMTP level, allowing the new "Reject" classification type to occur, rejecting a message before being accepted.

- SMTP Connection Checks / Reject Connections

A modification to SMTP Connection Checks has been made to allow the capability to reject connections versus receiving and then deleting the message. Connection Checks will begin checking as soon as the data is received from the SMTP client.

This SMTP Connection Check modification also allowed the capability to add Reject Connection as a new option to the following IMail Server features:

Upgrades will not affect any previous settings for Administrators that are using this feature. The Delete Message option functionality will still function as in previous versions. Administrators must also be aware that when the option Reject Connection is used, the validation will run during the MAIL FROM command.

Note: New installations will by default will not have Connection Checks or SPF enabled.

- "adduser.exe"

"adduser.exe has been rewritten to handle internationalization for the Full Name.

- OpenSSL

WorkgroupShare incorporates the capability to share Outlook data, such as calendars, tasks, contacts, distribution lists, notes, and e-mail for all IMail users. In addition to sharing users' personal folders with other users, WorkgroupShare lets you define public shared folders such as shared contact lists and holiday calendars with other users.

WorkgroupShare now has the capability to allow all users to synchronize their mobile devices with their Outlook folders to include e-mail, contacts, calendar, tasks and notes. Users can maintain their contacts and calendar appointments from either their computer or mobile device, and remain synchronized. See the IMail Administration Help > System Settings for more details on enabling this feature.


IMail Server Installation

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) 6.0 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 Administration and Web Client

After installation, you have the option to launch the IMail Web Administration automatically. If you choose not to launch IMail Web Administration 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 Administration.

For example:

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:

Web Messaging Notes for Upgrading

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.

WorkgroupShare Installation

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 v11.03 and Later

Customers with SQL/Access for User Database

Note: If the Administrator has a database backup made prior to the upgrade, a simple restore by the Administrator is all that will be necessary for downgrading the SQL/Access user database.

Customers downgrading with no user database backup from before the IMail Server v11.03 upgrade, will need to follow the instructions at the following KB:

Customers with IMail User Database

Correcting "Reject Connection" Option for Commtouch Premium Anti-spam

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 and later to v10.01 or earlier will cause the Premium Anti-spam 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 and 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


Uninstalling IMail Server

  1. Open the Add/Remove Programs applet in the Windows Control Panel.
  2. Select the IMail Server Edition you want to un-install.

Removing IMail Server using the Add/Remove Programs does not delete the IMail directory or the subdirectories and files. These must be deleted manually.
Everything is deleted in the Windows registry under HKEY_LOCAL_MACHINE\Software\Ipswitch\IMail (only 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.

Removing WorkgroupShare

WorkgroupShare is a component of your IMail Server. To remove only WorkgroupShare select the Modify option in your IMail Server.

  1. Open the Add/Remove Programs in the Windows Control Panel.
  2. Select your IMail Server edition and click the Modify button.
  3. This will initiate the IMail Server Install program, click Next until the Program Maintenance window and select Modify.
  4. Click the icon Custom Install Options by WorkgroupShare Server and select "This feature will not be available", and click Next.
  5. Click Install to initiate the removal of WorkgroupShare from your IMail Server.
