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
IMail now uses the Open SSL library.
IMail now uses the Open LDAP server.
IMail Anti-spam will search for phrases in the subject.
IMail Anti-spam now has the option to modify the subject for
messages identified as spam.
Optional Enhancements
IMail Anti-Virus products provide 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 products stop dangerous viruses before they make it to
an end-user's e-mail client.
o IMail Anti-Virus premium
IMail Anti-Virus premium fully integrates with IMail Server
and is powered by Symantec CarrierScan Server, a high performance,
scalable, reliable solution to protect against viruses.
o IMail Anti-Virus Standard
IMail Anit-Virus standard fully integrates with IMail Server
and is powered by BitDefender(TM), a reliable solution to
protect against viruses.
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.
o If you are upgrading from a previous version of IMail
a conversion of the LDAP database will take place. This
conversion can take a lengthy amount of time depending on
the number of domains converted. The LDAP server will also
be left running after the conversion.
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.
MESSAGING ENHANCEMENTS
In this release, the ClassicWebMail templates have been added
as the default web templates for IMail. The stylish and
sophisticated look of ClassicWebMail adds ease of use to the
web messaging experience. Apparent changes made to these web
files in this release include:
o Context sensitive help for associated pages
o Ability to view mail message headers on the Read Mail page
o Anti-Spam interface updates to the Host Black List, Phrase
Filtering, Statistical Filtering, HTML Feature Filtering,
URL Domain Black List, and Domain/Email Addresses pages.
o Anti Virus interface updates to the Anti Virus
Administration page

WEB CALENDARING NOTES FOR UPGRADERS
There were no updates to the Web Calendaring templates
in this release.
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.
o The IMAP server may crash if the SQL server is not started
and ACLs are enabled.
o SETACL does not support the + or - modifiers on the ACL
string. This does not affect Bynari Connector.
RELEASE NOTES
o The function of the 'Hide from Information Services' feature has
changed. There is currently no way to hide information within an
OpenLDAP database. When this option is applied, LDAP information
for the user is deleted from the LDAP database and must be
re-added should you wish to show LDAP information for this user
again.
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 v8.1 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 v8.1. 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
------------------------ --------
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
SPELLENBL INTEGER -1
NUMSGSTNS INTEGER -1
IWDEPTH INTEGER -1
PRVWSIZE INTEGER -1
STRTDAY INTEGER -1
ENTRYGRNL INTEGER -1
STARTTIME INTEGER -1
ENDTIME INTEGER -1
MAXEVNTDISP INTEGER -1
MAXTSKDISP INTEGER -1
MAXNOTEDISP INTEGER -1
MAXDLYRCURCNT INTEGER -1
MAXWKLYRCURCNT INTEGER -1
MAXMONRCURCNT INTEGER -1
MAXYRLYRCURCNT INTEGER -1
DISPCMPLTDTSKS INTEGER -1
HOURSCLOCK INTEGER -1
MAXSRCHRESPPG INTEGER -1
MAXEVENTTITLELEN INTEGER -1
MAXTASKTITLELEN INTEGER -1
CONFIRMONDELETE 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.
