Go to the SETUP directory, and type UPDATE. Follow the instructions displayed on the screen. 1.4 New Functionality in This Release This release of Microsoft Exchange Server includes new client support and a number of new features. These are described below. 1.5 Macintosh Client Microsoft Exchange Client for the Apple Macintosh adds to the client platforms available in Microsoft Exchange Server 4.0. The Microsoft Exchange Client for the Apple Macintosh supports advanced features such as grouping and filtering in views, discussion databases, auto-signature, rules, sending/sharing of documents, digital signatures, offline folders, and access to the Internet through the Internet Mail Connector 1.6 PowerPC Client Microsoft Exchange Client for Windows NT is also available for the PowerPC platform. 1.7 PowerPC Server Microsoft Exchange Server also adds the server software for the PowerPC platform. With this addition, Microsoft Exchange Server completes its support for high-end hardware platforms, offering the same advanced functionality such as security integrated into the network operating system, use of server operating system monitoring, and backup tools on Intel and RISC platforms. 1.8 Internet Mail Connector and Macintosh File Attachments With the release of Microsoft Exchange Server, all file attachments from an Apple Macintosh will be mapped to MIME-standard bodyparts so that MIME complaint clients and gateways can decode these attachments. Additionally, the Internet Mail Connector maps any incoming bodyparts to windows or Macintosh file types. 1.9 Internet Mail Connector Supports Dial-up Connections This release enables support of dial-up connections by the Internet Mail Connector to send/receive messages to Internet service providers over a telephone connection. 1.9.1 Administrator Permissions Required to Run the Internet Mail Connector To administer the Internet Mail Connector, the account under which you are running the Microsoft Exchange Server Administrator program must have administrative rights on the computer where the Internet Mail Connector service is running. This account must be listed as a member of the Administrators group in the User Manager for that computer. If the account does not have administrative rights, an error message will be displayed when you attempt to open the Internet Mail Connector properties, and some fields will be disabled. 1.9.2 Internet Mail Connector Word Wrap and Text Quoting Registry Parameters Two new registry values have been added under the Internet Mail Connector's Parameters key to provide control over the Internet Mail Connector 's word- wrap and text quoting behavior. The first, UseRTFText, is a DWORD value that specifies if reply and forward text will be quoted in outgoing non- TNEF. If it is enabled (non-zero), Internet style quoting is applied to reply and forward text by inserting a ">" character before each line. If UseRTFText is disabled (set to zero or not present), no Internet style quoting is applied. UseRTFText is enabled by default. The second new registry value is EnableMIMEWrap. This is a DWORD value that controls word-wrap in outgoing non-TNEF MIME messages. If it is enabled, lines in MIME messages are wrapped at a fixed column. If EnableMIMEWrap is disabled (and UseRTFText is also disabled), lines are wrapped using quoted printable encoding. MIME enabled readers will unwrap the lines, restoring the original text flow, but users with non-MIME readers will see a "=" character appended to each wrapped line of text. EnableMIMEWrap is enabled by default. Note that UseRTFText also affects word-wrap. If enabled, text lines in all non-TNEF messages are wrapped at a fixed column, regardless of the setting of EnableMIMEWrap. The word-wrap setting for non-MIME messages on the Internet Mail Connector properties in Microsoft Exchange Server Administrator program is ignored. 1.9.3 Using Internet-style Quoting with List Servers When the UseRTFText registry parameter is enabled, Internet style quoting will be applied to forward and reply text in messages. This quoting will also be applied to text that is cut and pasted from a message into a compose note. When sending a message with a command to a list server, it is important to make sure the text is not quoted; otherwise, the list server will not be able to interpret the command. You can type the command manually. Alternatively, you can use the Paste Special command to paste the plain text. Do not paste the formatted text. 1.9.4 Site Address Required to Start the Internet Mail Connector The Internet Mail Connector determines the domain to use in the originator address for reports from the site address for its address type. If you set the address type on the Internet Mail property page of the Internet Mail Connector properties to a type for which there is no site address, the Internet Mail Connector will not start. If you want to set an address type without specifying the site address, you can modify the registry by adding the value SiteDomain to SYSTEM\CurrentControlSet\Services\MSExchangeIMC\Parameters. SiteDomain is a REG_SZ value that should be set to the domain you would like to be used in the originator address for reports generated by the Internet Mail Connector. 1.9.5 Sending Imported Messages Using the Internet Mail Connector Messages that have been imported into Microsoft Exchange with the migration tools cannot be embedded in messages and sent through the Internet Mail Connector. The Internet Mail Connector will not be able to process the embedded message and will generate a non-delivery report (NDR). The problem will also occur if you try to embed an unsent message into another message and send it out the Internet Mail Connector. To work around this problem, cut and paste the contents of the migrated message or forward it instead of embedding it in another message. 1.9.6 The Microsoft Exchange Server Routing Table The Internet Mail Connector reads the Microsoft Exchange Server routing table every 15 minutes to determine its routing responsibilities. The 15- minute interval is configurable through the Windows NT Registry. It is recommended that you use this default setting (0xF), but if you need to modify it, use the following registry key: SYSTEM\CurrentControlSet\Services\MSExchangeIMC \Parameters\RouteCalculationInterval Note Setting this registry value to 0x0 means the Internet Mail Connector would check the routing table only at startup. The Internet Mail Connector checks the Last Modified field for the routing table to determine whether changes have been made. If the Last Modified time on the routing table is newer than the timestamp on the Route.txt file, the Internet Mail Connector will update its routing information and create the Route.txt file in the Exchsrvr\Imcdata\Log directory. Using the Route.txt File The Route.txt file contains the current routes that the Internet Mail Connector will use to determine delivery destinations for connected sites. This file is not used by the Internet Mail Connector for routing; it's a text representation of the routes that the Internet Mail Connector is responsible for. If changes are made to the routing table, at the next checking interval, the Internet Mail Connector will copy the existing Route.txt file to Route.old and update the Route.txt file with the latest changes. The Internet Mail Connector always reads the routing table at startup. Troubleshooting a Routing Problem If the Internet Mail Connector does not route properly, check the following configuration items: Check the entries in the Control Panel, Network, TCP/IP, and DNS configuration. The host name and domain name need to be reachable by other computers (that is, registered within the DNS or specified in the local HOSTS file). Check the Internet Mail Connector Connected Sites property page to ensure that all entries are correct. Check the routing table using the Site Addressing object, Routing property page in the Microsoft Exchange Server Administration program. Additionally check the following files: Route.txt: The current routes the Internet Mail Connector services. Route.old: The previous routing information the Internet Mail Connector used before it created the new Route.txt file. Equal Cost Routes and Non-Delivered Mail If your configuration consists of multiple routes with the same cost for a destination, the Internet Mail Connector will balance loads between the different routes. If a route has problems, any queued mail for that destination will not be rerouted through a different route. If the problems continue longer than the maximum allowed delivery time-outs, a non-delivery report will be generated in these cases. Least Cost Routes If your configuration contains multiple routes to the same destination with different costs, the Internet Mail Connector will use only the least cost route defined. If that link is unavailable due to a communication problem, the Internet Mail Connector will not use any of the higher cost routes. Proper configuration of your DNS with MX records can override this behavior and allow all incoming mail to use a secondary route. Routing Table Can't Be Read If the Internet Mail Connector has started and the routing table cannot be read at the specified checking interval, the Internet Mail Connector will continue to use its existing routing information. No event is logged in this case. Correction to the Administrator's Guide In the "Using Routing Addresses for Address Space Entries" section in Chapter 11, The Routing Address tab no longer needs to be used when connecting two replicated Microsoft Exchange sites. It can be used to send mail to different organizations that are not replicated. 1.9.7 Maximum Number of Inbound and Outbound Connections Setting the maximum number of inbound and outbound connections to 0 on the Connections property page does not stop the Internet Mail Connector from accepting inbound or attempting outbound connections. To stop both inbound and outbound connections, set the Transfer Mode to None. To stop inbound connections, choose Outbound only. To stop outbound connections, choose Inbound Only. 1.9.8 Removing an Installed Internet Mail Connector Before removing the Internet Mail Connector, be sure there are no messages left in the queues awaiting delivery. Follow these steps: 1. On the Connections property page, set the transfer mode to None (Flush Queues). 2. Set the retry interval for the connector message queues to a short interval, such as .25 (15 minutes). 3. Set the message time-outs for normal, urgent, and non-urgent mail to one hour. 4. Restart the Internet Mail Connector. The Internet Mail Connector will not accept new messages and will continue to process the messages already in its queues. Non-Delivery Reports (NDRs) will be generated for any messages that cannot be delivered in one hour (host unreachable, for example). Check the status of the queues on the Queues property page. When the queues are empty, shut down the Internet Mail Connector and begin removing the installation. 1.9.9 Loopback Detection The Internet Mail Connector will allow configurations where SMTP connections are made to itself. There are cases where this behavior is desired, such as when one Microsoft Exchange user addresses another using an SMTP proxy. However, this can also allow loopbacks and inefficient configurations. You can configure the Internet Mail Connector so that it won't initiate SMTP connections if the destination host's IP address matches its own. Instead, it will create a non-delivery report (NDR) for the message. To enable the Internet Mail Connector's connection loopback detection, create the following DWORD registry value and set it equal to 1: SYSTEM\CurrentControlSet\Services\MSExchangeIMC \Parameters\DisableLoopbackConnection 1.9.10 Delivery Restrictions for Custom Recipients Delivery of inbound messages to custom recipients cannot be controlled using the Delivery Restrictions property page. 1.9.11 Internet Mail Connector Performance Monitor Counters The Microsoft Exchange Server Performance Monitor Counters for the Internet Mail Connector described in Chapter 17 of the Administrator's Guide have changed. Name Description Counters for MTS-IN Queued MTS-IN The number of messages awaiting final delivery in MS Exchange Server Bytes Queued MTS-IN The size, in bytes, of the messages that have been converted from Internet Mail and are awaiting final delivery within MS Exchange Server Messages Entering MTS-IN The number of messages entering the MTS-IN folder after conversion from Internet Mail format Counters for MTS-OUT Queued MTS-OUT The number of messages waiting to be converted to Internet Mail format Bytes Queued MTS-OUT The size, in bytes, of the messages waiting to be converted to Internet Mail format Messages Entering MTS-OUT Messages that have entered the Internet Mail Connector's MTS-OUT folder for conversion to Internet Mail format Messages Leaving MTS-OUT The number of messages entering the Outbound Queue Associations Connections Inbound The number of current SMTP connections to the Internet Mail Connector established by other SMTP hosts Connections Outbound The number of current SMTP connections the Internet Mail Connector has established to other SMTP hosts Connections Total Outbound The total number of successful SMTP connections that the Internet Mail connector has established since it was started Connections Total Inbound The total number of SMTP connections the Internet Mail Connector has accepted from other hosts since it was started Connections Total Rejected The total number of SMTP connections that the Internet Mail Connector has rejected from other hosts since it was started Connections Total Failed The total number of SMTP connections the Internet Mail Connector has attempted to other hosts that failed since it was started Internet Queues Queued Outbound The number of messages from MS Exchange Server that are queued to be delivered to the Internet Queued Inbound The number of messages received from the Internet destined for MS Exchange Server Counters for NDRs NDRs Total Inbound The total number of Non-delivery reports generated for outbound mail NDRs Total Outbound The total number of Non-delivery reports generated for inbound mail Counters for Messages/Bytes Transferred Inbound Bytes Total The total size in Bytes transferred into MS Exchange Server Outbound Bytes Total The total size in Bytes transferred from MS Exchange Server Inbound Messages Total The total number of Internet messages delivered into MS Exchange Server Outbound Messages Total The total number of outbound messages delivered to their destinations 1.9.12 Internet Mail Connector Queues The "Selecting a Queue" section in Chapter 17 of the Administrator's Guide has changed. Option Description Inbound messages awaiting conversion Incoming messages waiting to be converted by the connector and then delivered to the information store. Inbound messages awaiting delivery Messages in the MTS-IN folder in the information store. Outbound messages awaiting conversion Outgoing messages received from the MTA and waiting to be converted by the Internet Mail Connector. The next destination is the Out queue. Outbound messages awaiting delivery Messages queued for delivery in the Internet Mail Connector's scheduler, which roughly corresponds to the message files in the IMCDATA\OUT directory. Since some messages require delivery to multiple hosts, there will be more entries in the queue than there are files in the directory. 1.9.13 Using a Wildcard MX DNS Record If you are using a wildcard MX DNS record, the Internet Mail Connector will append the default domain from your TCP/IP configuration to each host name before trying to resolve it in DNS. To prevent this, create a REG_DWORD registry value named DisableResolverSearchList under the SYSTEM\CurrentControlSet\Services\MSExchangeIMC\Parameters key and set its value to 1. This will stop the Internet Mail Connector from appending a domain to host names before trying to resolve them. 1.9.14 Using the Internet Mail Connector as a Site Connector In Chapter 8 (Planning Your Connectors) of the Microsoft Exchange Server Concepts and Planning Guide, the "Connecting Microsoft Exchange Server Sites over the Internet" section has changed. The following information supplements the section and describes steps that can be eliminated. Step 1: Multiple Internet Mail Connectors in one site is no longer required. Step 8: The address space routing address is no longer required. Sites that can be connected (reached) only through site B (that is, site A has no direct connection to them) do not need to be added to the Connected Sites property page on the Internet Mail Connector on site A. The Internet Mail Connector reads the routing information from the Microsoft Exchange Server routing table and determines that these sites are routable through site B. Step 9: You no longer have to add routing addresses for address spaces that are serviced on other sites that an Internet Mail Connector will connect to. When sites are replicated, the Internet Mail Connector will access this information directly. In addition to the steps in the Concepts and Planning Guide, use the following steps to connect Site A and Site B: 1. Use the Connected Sites property page on site A to add a new connected site for site B. 2. Using the Routing Address tab from the Connected Sites property page, add the routing address for the Internet Mail Connector computer on site B. 3. Add site A to the Connected Sites property page for the Internet Mail Connector on site B and use the routing address for site A. Step 10: It is no longer necessary to define custom recipients in the site where the Internet Mail Connector servicing the external Internet mail resides. 1.9.15 Connecting Sites with the Internet Mail Connector For best performance when connecting sites, configure the Internet Mail Connector to use MIME encoding. When sending TNEF, the Internet Mail Connector handles attachments differently when performing MIME encoding than it does with uuencode. Attachments are transmitted in the TNEF data, instead of being broken out separately, as they are in uuencoded messages. Due to the internal design of the Internet Mail Connector, this results in much better performance in processing TNEF messages. Therefore, to maximize site replication performance, it is recommended that you use MIME encoding with TNEF when connecting sites using the Internet Mail Connector. 1.9.16 Do Not Use an Ending Period to Specify an FQDN When specifying message delivery by domain, a fully qualified domain name (FQDN) ending with a period (.) is not supported. A non-delivery report (NDR) specifying "host unreachable" will be generated. 1.9.17 Specifying the Maximum Message Size The description of the No limit option on the Internet Mail Connector General property page in the "Specifying the Maximum Message Size" in Chapter 11 of the Microsoft Exchange Server Administrator's Guide should read as follows: Send an inbound or outbound message of any size. 1.9.18 Forwarding Outbound Mail to a Host Using Dial-up The Internet Mail Connector has a default setting that creates up to 10 outbound connections to any particular host and sends up to 8 messages in any single connection. For performance reasons, you should consider changing the settings to 1 for outbound connections and to 100 for maximum messages. To change these settings: 1. In the Administrator window, choose Connections. 2. Double-click the Internet Mail Connector. 3. Select the Connections tab. 4. Under Transfer Mode, choose Advanced. 5. Change the defaults to the following: Max no. of Connections to a single host: 1 Max no. of Messages sent in a connection: 100 Note Check with your Internet service provider to make sure the receiving host can accept 100 messages in a single connection. 1.10 Double-byte Character Set (DBCS) Support With the release of Microsoft Exchange Server, all versions accept and can administer all other versions.
