Defect Fixes for v12.5.7

Web Client

• Downloading messages would fail if the message subject contained a character not valid for a file name.
• Additional lines sometimes inserted at the end of messages when sent.
• Filenames not correctly showing when header folding was done with spaces and not tabs.
• Plain text warning message has been removed from the plain text body part.
• Attachments with filenames encoded using filename* syntax were not decoded correctly.
• Task Calendar back button not functioning.
• Telerik controls updated.
• Stack Overflow error when viewing messages with malformed HTML.
• HTML Messages would fail to create a new line when composing a message in IE
• Unable to send messages when SMTP Auth was disabled in SMTP

Web Admin

• Unable to download log file.

Collaboration

• Systems with a large number of users would get a timeout error when attempting to configure permissions from the Outlook Plugin.
• Windows Updates released on Oct 10, 2017 caused the Outlook Plugin to hang when syncing with the IMail Server.

SMTP / Queue Manager

• IP addresses not assigned to an IMail Domain were sometimes not correctly sending the initial banner message upon connection.
• Kill list was bypassed by including spurious < or > characters at the end of the from address.
• DNS Lookup diagnostic log messages added when debug logging is enabled.

IMAP

• Memory Leak in Fetch command.

Maintenance Service

• Several errors regarding database cleanup tasks were addressed.

Utilities

• IMailConfigExport.exe incorrectly wrote values for some QWORD registry values

Known Issues

• When the Store Mailbox Metadata in SQL Database option is enabled, using versions of the IMail Utilities Pack prior to 12.5.4 will cause an unnecessary conversion of mailbox metadata to flat file storage and then back to the Database. Mailboxes will be inaccessible while this conversion is occurring.
• Mail Collector does not honor maximum mailbox size limits placed on users. If a limit is imposed on a user and they configure a Mail Collector account they can exceed their maximum mailbox size which will cause messages sent to the user to be returned to the sender.
• Upgrade Note: If you are upgrading to Imail version 12 or newer from a prior version, we recommend that the collaboration database be converted from the default Microsoft Access database to a more robust SQL Express database. The version 12 web messaging uses this database more heavily than prior versions and may experience performance problems if not converted. For more information on how to convert the database, please see the following article: http://ipswitchmsg.force.com/kb/articles/FAQ/IMail-Utilities-Converting-Web-Mail-Personal-Contacts-or-Calendar-from-Access-to-SQL-or-SQLExpress-for-IMail-11-03-and-newer-1307739597574
• For Windows Server 2012 administrators that are installing IMail Server. Ipswitch recommends that IMail Server be configured to use SQL Server for improved performance. Windows Server 2012 does not support SQL Server 2008 which is delivered by the IMail Server install. There are two possible options:
  1. Manually download and install SQL Server 2012 from Microsoft before installation of the IMail Server. After SQL Server 2012 is successfully installed be sure to select "Use Existing Local SQL Server" when installing the IMail Server.
  2. Remote SQL Server (any version) access is also possible as long as the SQL Server is a member of the same Active Directory Domain as the IMail Server installation. See Remote Setup.
• IIM 2.08 Standalone upgrade to IMail Premium. The Conversation Store is located in a different directory. Files require copying the old conversation store from the old directory to the new directory.
• LDAP Service will not start on Domain Controllers due to Active Directory being bound to the standard LDAP port.
• Droid Mobile Devices and Windows Mobile 6.5. When accessing Public Folders (Contacts and Calendars), and Shared User Folders (Contacts and Calendars), do not have the capability to display on current Droid mobile devices.
• Tasks. Outlooks task recurrence option named Regenerate new task after each task is completed, is not handled correctly for all recurrence patterns when synchronized and saved to the IMail Collaboration database. The web client will not display the tasks correctly.
• Calendar. Creating a yearly recurring appointment in Outlook using the "Recur every XX years" will be ignored by the web client and by default use every year. Should the appointment be saved with the Web Client then IMail Collaboration will synchronize and modify Outlook to also reflect every year.
• External User Database customers using the Maximum Mailbox Size with users Maximum Mailbox Size set to 2GB. The database saves 2GB as -2147483648 (instead of 2147483648). When this negative value is converted to unsigned, the value becomes 9223372036854775807 which is 8589934591 GB. Customers will be required to manually update these users or use the bulk edit command available with the Console Administrator to correct these values.
• Windows Mobile devices are unable to accept or view meeting invitations. Meeting invitations will arrive as an attachment.dat file. Windows Mobile can send meeting invitations.

Product Description

IMail Server is an Internet standards based mail server system for Microsoft Windows 2008, and Microsoft Windows 2012. IMail Server includes powerful anti-spam management tools, a new Web-based administrator and client, and implements a series of programs that run as services including:

• Simple Mail Transfer Protocol (SMTP) service for sending and receiving mail over the Internet or in an internal TCP/IP network.
• Post Office Protocol, version 3 (POP3) service to allow POP3 clients (such as Microsoft Outlook Client and Qualcomm Eudora) to download mail from the IMail Server.
• Internet Message Access Protocol, version 4 (IMAP4) service to allow IMAP4 clients (such as Mozilla Thunderbird and Microsoft Outlook) to access mail on the IMail Server.
• Lightweight Directory Access Protocol (LDAP) Version 2.1.22 service for publishing user information in an LDAP directory.
• Language support for Web Messaging: English, French, Italian, German, Spanish, Chinese Simplified, Chinese Traditional and Japanese.
• List server for creating and managing mailing lists.

IMail Server Product Features

• Web Client lets you send and receive mail using a web browser. You can log on to the Web Messaging from a browser on any computer with a supported browser and manage e-mail without installing e-mail client software. When a user creates a mailbox in the Web client, the mailbox is created on the mail server and mail folders and messages reside on the server.
• Lite Web Client (Low bandwidth mail client) allows mobile users capability to access their mail quicker. To allow this capability, framesets, icons, and certain processes were removed to allow faster processing.
• IMail Web Administration (Server) provides local or remote access to IMail Server administration features via a Web browser and/or console server. You can administer all e-mail functions, including users, groups, services, shared calendars and contacts, and anti-spam and anti-virus settings.

IMail Collaboration

IMail Collaboration is now integrated into all IMail Server products to allow all users the greatest benefit for data sharing. IMail Collaboration 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, IMail Collaboration lets you define public shared folders such as shared contact lists and holiday calendars with other users.

IMail Collaboration 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.

Installing/Upgrading/Repairs

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) 7.0 or later and Microsoft® .NET Framework 4.0 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:

• Type "http://mail.domain.com/IAdmin" in the browser and press ENTER. The Ipswitch Web Administration login page appears.

  -OR-

  Click Start > Programs > Ipswitch > IMail Server > IMail Web Administration. The Web Administration 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:

• Type "http://mail.domain.com/IClient" in the browser then press ENTER. The Ipswitch Web Client login page appears.

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.

IMail Collaboration Installation

• The IMail Collaboration installation is a component of the IMail Server installation.
• If you are upgrading from an IMail Server without IMail Collaboration or if you did not install IMail Collaboration, a backup of the WorkgroupShare.mdb file (located under "...\IMail\WorkgroupShare\Data".
• To save existing contacts used for your Web Client or Microsoft Outlook, after installing IMail Collaboration, import the contact database located at "...\IMail\WorkgroupShare\Data\WorkgroupShare.old.mdb" to "...\IMail\WorkgroupShare\Data".

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

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:

http://kb.imailserver.com/cgi-bin/imail.cfg/php/enduser/std_adp.php?p_faqid=1206

Customers with IMail User Database

http://kb.imailserver.com/cgi-bin/imail.cfg/php/enduser/std_adp.php?p_faqid=1213

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

Customers using IMail Premium CYREN Anti-spam with the new "Reject Connection" settings, will need to save the settings before downgrading, or modify the registry keys manually. The registry keys are located at: "HKLM\SOFTWARE\Ipswitch\domains\Domain Name\"

Registry Key	Type	Value
SpamConfirmed\Action	REG_DWORD	Valid values are 0-4 0 = None 1 = Delete Message 2 = Forward to Address 3 = Insert X-Header 4 = Move to Mailbox
SpamBulk\Action	REG_DWORD	Valid values are 0-4
SpamSuspected\Action	REG_DWORD	Valid values are 0-4

Correcting "Reject Connection" Option for SPF Filtering

"HKLM\SOFTWARE\Ipswitch\domains\Domain Name\"

Registry Key	Type	Value
SPFError\Action	REG_DWORD	Valid values are 0-4 0 = None 1 = Delete Message 2 = Forward to Address 3 = Insert X-Header 4 = Move to Mailbox
SPFFail\Action	REG_DWORD	Valid values are 0-4
SPFSoftFail\Action	REG_DWORD	Valid values are 0-4
SPFTempError\Action	REG_DWORD	Valid values are 0-4

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:

http://kb.imailserver.com/cgi-bin/imail.cfg/php/enduser/std_adp.php?p_faqid=236

Once a user has installed and been licensed with CYREN 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 IMail Collaboration.

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

1. Open the Registry Editor and locate the following key:
   HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall\{42A05E51-7514-4330-A784-B4C45412F04D}
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

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.

Note:
• 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.

IMail Collaboration is a component of your IMail Server. To remove only IMail Collaboration 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 by Collaboration and select "This feature will not be available", and click Next.
5. Click Install to initiate the removal of IMail Collaboration from your IMail Server.
