DESCRIPTION
===========
IMail Server is an Internet standards based mail server system for Microsoft Windows NT 4.0 (Service Pack 6) and later, Windows 2000, Windows 2003, and Windows XP Professional. IMail Server consists of a series of programs that run as services on the Windows system, 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 IMail Client and Eudora) to download mail from the IMail Server.

Internet Message Access Protocol, version 4 (IMAP4) service to allow IMAP4 clients (such as Netscape Communicator and Internet Explorer) to access mail
on the IMail Server.

Lightweight Directory Access Protocol (LDAP) Version 3 service for publishing user information in an LDAP directory.

A List server for creating and managing mailing lists.

IMail Server can monitor any of these services, notify you when they are down, and automatically restart a service.

Web Messaging lets users access their mail on the IMail Server system from any Web browser on the Internet. It also provides remote management capabilities for IMail administrators. Web Messaging can also display banner ads at the top of the Web Messaging mail screens.

Mail to Pager/Beeper lets you set up aliases on the IMail Server system that can receive mail from a mail client and forward it to preconfigured pager or beeper addresses.

NEW FEATURES
============
o IMail Administrator (IAdmin)
- Copy and Bounce for inbound rules

o Queue Manager
- A Queue Manager service has been added to IMail that controls message delivery.

o Anti-Spam content and connection filtering

Optional Enhancements
=====================
o IMail Anti-Virus
IMail Anti-Virus fully integrates with IMail Server and is powered by Symantec CarrierScan Server, a high performance, scalable, reliable solution to protect against viruses. IMail Anti-Virus provides administrators a powerful all-in-one anti-virus solution that is easy to install and use. Designed to work exclusively with IMail Server, IMail Anti-Virus stops dangerous viruses before they make it to an end-user's e-mail client.

o Mail to Fax
IMail Server's Mail-to-Fax Option is an add-on (not included in base price) that allows system administrators to create special aliases that route messages directly to a fax machine. This option allows ISPs, for example, to set up e-mail accounts for customers who do not have a PC or Internet access and want to receive e-mail messages via a fax machine. With this option, other users could send fax messages from their desks by sending e-mail to a special account on a local server that faxes it to the recipient.

INSTALLING/UPGRADING
====================
o If you purchased an IMail CD-ROM, insert the IMail Server CD in a drive. If the CD does not run automatically, select Run from the File menu, and then enter the CD path followed by autorun.exe.
o If you downloaded the IMail install program from the Internet, run the downloaded application. 
o If you are currently using an external user database with an earlier (pre-v7.0) version of IMail, you must add a new set of required columns to the database table in which user information is stored. Please refer to the "External Database Changes" entry in the Release Notes section of this document for details.

UNINSTALLING
============
Use the Add/Remove Programs applet in the Windows NT Control Panel. The following happens:
o IMail services are removed from the Control Panel Services.
o Everything is deleted in the Windows NT registry under
HKEY_LOCAL_MACHINE/Software/Ipswitch/IMail (but does not remove the Ipswitch key).
o 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.

Note: 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.

Web Messaging enhancements for administrators
=============================================
o Web Messaging templates have been updated to support Anti-Spam configuration.

o Web Messaging templates have also been updated to support new inbound rule actions for copy and bounce.

Web Messaging enhancements for users
====================================
o Web Messaging templates have been updated to support new inbound rule actions for copy and bounce.

WEB CALENDARING NOTES FOR UPGRADERS
===================================

v8.0
==================
There were some Web Calendaring Template changes made to this release version. All of these changes were made to the JavaScript code, which did not affect the user interface of the templates.

The following templates were altered:
o addevent.html
o addtask.html
o editevent.html
o edittask.html
o jsadevt.js

SECURE SOCKETS LAYER (SSL)
==========================
You can check the following if you are having trouble getting SSL to work:

o IWebMsg.ini should have EnableSSL=1 (ForceSSL=1 may or may not be there).

o IWebMsg.ini is in the proper windows directory (%WINDOWS% usually \Winnt).

o After changing IWebMsg.ini, stop the service and restart it again to have changes recognized by the application.

o Select "Allow Service to interact with Desktop" to see if there is any dialog box from SSL.DLL like initialization failure because the certificate or key file is not found. If SSL.DLL initialization has failed, then the application will not continue.

o If the application is running but SSL is not working, EnableSSL is the only problem.

o SSL.CGI allows change from secure to non-secure mode. If SSL is disabled, then changeover from secure to non-secure is not allowed; hence SSL.CGI is not parsed.

o 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.

KNOWN ISSUES
============
o The IMail shortcuts are not always installed on traditional Chinese. They should be manually created in this case.

RELEASE NOTES
=============
o The X-IMail-Rule header can be disabled by adding the following registry key:

HEY_LOCAL_MACHINE\SOFTWARE\Ipswitch\IMail\Global\BlockRuleHdr

This should be a DWORD value and should be set to non-zero value to block this header from being created. This is a server wide setting and affects all domain and user rules on the server.

o External Database Changes:
IMail supports multiple database connections. Enabling this feature will improve performance when using an external database. This can be enabled by creating and setting two registry keys:

HKEY_LOCAL_MACHINE\SOFTWARE\Ipswitch\IMail\Global\UseMultiConnect
HKEY_LOCAL_MACHINE\SOFTWARE\Ipswitch\IMail\Global\MaxConnect

The first key, UseMultiConnect should be set to 1 to enable multiple database connections. The second key, MaxConnect should be set to the maximum number of connections allowed, 10 is recommended.

When installing IMail v8.0 over any version earlier than 7.1 in which one or more hosts are configured to use an external user database, new columns must be added to the database tables. This is due to additional user-level data which must be stored for use with the new Web Messaging features and for Web Calendaring. These new columns must be added to the user table for each IMail host configured to use an external database.

NOTE: If a custom ODBC driver was used with an earlier version of IMail, the driver must be modified to accommodate the new columns. Source code for the basic ODBCUser.dll driver (tailored for SQL Server and Access) may be obtained by download from the IMail Support Center:

ftp://ftp.ipswitch.com/Ipswitch/Product_Support/IMail/odbcuser.dll

These database column additions must be made before installing IMail v8.0. Also, if a custom ODBC database driver will be used with IMail, it must be created and
ready for use. New columns and their types are as follows:

IMail Server v7.1 New Columns
Database Column Default
Name Type Value
------------------------ --------
NUMNOTIFY INTEGER 0
LASTNOTIFY INTEGER 0

IMail Server v7.0 New Columns

Database Column Default
Name Type Value
------------------------ --------
NUMTRIES INTEGER 0
ATTEMPTTIME INTEGER 0
NUMTIMESSUSP INTEGER 0
LASTLOGIN INTEGER 0
SPNDUSRACCT INTEGER 0
IWOPTIONS INTEGER 0
SPELLCHKG INTEGER 0
ICALENBL INTEGER -1

TIMEZONE VARCHAR(255) "" (empty string)
DEFVIEW VARCHAR(40) ""
DEFCALNM VARCHAR(40) ""

For all existing user records, these columns should be set to the default values shown in the table above.

Please note that when all domains use the IMail and/or NT user databases, these changes do not apply. Also, when creating a new external database, these columns will be automatically generated as the table is created.
