IMail Server is an Internet standards based mail server system for Microsoft Windows NT 4.0 (Service Pack 6) and later, Windows 2000 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 4.0 and Internet Explorer 4.0) 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 pre-configured pager or beeper addresses. 

NOTE: Also available as a separate purchase, the Mail to Fax option lets you set up mail accounts on the IMail Server system that can receive mail from a mail client and forward it to Fax phone numbers. 

o IMail Administrator (IAdmin)
- Multiple condition rules support
- Anti Virus by domain
- Rules can send to mailbox or address
- Outbound rule support
- Max outbound message size
- Full mailbox notification (by percent full)
- Sub mailbox creation control

o SMTP32
- X-Imail-Rule header will be added to locally delivered messages that were trapped by a rule.

o Web Messaging
- 128 bit SSL support for more secure transmissions.
- Improved administration capabilities to match IAdmin rules, outbound message size, sub mailbox creation and full mailbox notification.

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.

Web Messaging enhancements for administrators 
o Web Messaging templates have also been updated to support Inbound and Outbound Delivery Rules, as well as multiple conditions for rules.

o The advanced SMTP options, such as maximum outbound message size, full mailbox notifications and sub-mailbox creation, can be configured on the Add Virtual Host and Modify Virtual Host Administration pages.

o If you have IMail Anti-Virus installed, administrators can also enable/disable virus scanning per domain from the Add and Modify Virtual Host administration pages.

Web Messaging enhancements for users 
o Web Messaging now supports 128 bit SSL for more secure transmissions.

o Users can create Delivery Rules for their incoming mail, and apply multiple conditions to each rule.

If you have customized templates that you wish to continue using, you may refer to the "Upgrading Customized Templates Document" for procedures to upgrade the old templates for use with IMail v7.0. If you choose to copy templates onto your system during the install, this document is stored as:
IMail\Web\New\Upgrade Help\upgrade6to7.txt 

The following templates were changed in this version:

- delconfirm.html
- msgsum.html (7)
- readmail.html (5)

(You can see what changed in \imail\web\Upgrade Help\upgrade6to7.txt.)

***NOTE: ONLY FOR 7.04 OR HIGHER UPGRADERS****************
| |
| If you have already updated delconfirm.html for |
| IMail 7.04 or higher, you need to remove the hidden |
| <INPUT> tag named "msgsort." This <INPUT> tag was |
| added to the delconfirm.html template in IMail 7.04, |
| and this element is no longer needed. |
| |

Changes made to the various templates are outlined in the "Upgrading Customized Templates Document." Below is a list of the templates that have been altered for 7.10. The number in parenthesis next to the file name indicates the numerical reference to the change applied to the file as outlined in the "Upgrading Customized Templates Document."
The following templates were changed in this version:
- chghostrule.html (2 - 6)
- chgrule.html (1 - 5)
- cs_help.cgi (1)
- listchgrule.html (2 - 6)
- readmail.html (4)
- sm_js2.cgi (1)
- vh_add.html (8 - 12)
- vh_modify.html (8 - 12)


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:
- addevent.html
- addtask.html
- editevent.html
- editimiprequest.html
- edittask.html
- yearview.html

You can check the following if you are having trouble getting SSL to work:

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

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

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

- 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. 

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

- 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.

- 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. 

o Page 4 of the IMail Server v7.0 User's Guide states that Web Calendaring has the" ability to import and export information to any compliant client, such as Outlook, and then import the information into a calendar or PDA." Web Calendaring does NOT have the ability to import or export. However, it can send and receive single events to and from MS Outlook and other compatible clients.

o Download the IMail Server User's Guide (.pdf file) from the Ipswitch Web site:

o Note: You will need the Adobe Acrobat Reader to view the .pdf file. You can also download the Acrobat Reader from the same location on our Web site.

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


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.

- Multiple condition rules are now supported in IAdmin and IWebmsg. The IMail client does not support multiple condition rules, but single condition rules are supported in the IMail client.

- External Database Changes:
IMail 7.1 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:


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 v7.1 over any earlier version, 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:

These database column additions must be made before installing IMail v7.1. 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
--------------------------- -----

IMail Server v7.0 New Columns

Database Column Default
Name Type Value
-------------------------- ------
TIMEZONE VARCHAR(255) "" (empty string)

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.
