Module 5 Managing Message Transport

Module Overview Overview of Message Transport Configuring Message Transport

Lesson 1: Overview of Message Transport Discussion: Overview of Message Flow Components of Message Transport How Are Messages Routed in an Exchange Server Organization? How Are Messages Routed Between Active Directory Sites? Options for Modifying the Default Message Flow Tools for Troubleshooting SMTP Message Delivery Demonstration: How to Troubleshoot SMTP Message Delivery

Discussion: Overview of Message Flow What is SMTP? What are the various message-flow scenarios? What type of message-flow scenarios do most organizations implement?

Components of Message Transport Component Description Submission queue Stores all messages on disk until processed Store driver Retrieves messages from sender’s Outbox Microsoft Exchange Mail Submission service Notifies a Hub Transport server in the local Active Directory site when a message is available for retrieval from a sender’s Outbox Categorizer Processes one message at a time from the Submission queue Pickup directory Submits messages to the Submission Queue

How Are Messages Routed in an Exchange Server Organization? Internet Hub Transport server Mailbox server Outlook client Client Access server

How Are Messages Routed Between Active Directory Sites? Default message flow Source Site Destination Site 10 Delayed fan-out Queue at the point of failure Default message flow Source Site Destination Site 10

Options for Modifying the Default Message Flow To modify the default message flow, you can: Configure hub sites to add additional hops to the message delivery Configure Exchange-specific routing costs to override the IP site link costs Configure expansion servers for distribution groups

Tools for Troubleshooting SMTP Message Delivery ToolDescription Exchange Server Best Practices Analyzer Use to check the configuration and health of the Exchange topology Exchange Mail Flow Troubleshooter Use to troubleshoot common mail-flow problems Queue Viewer Use to view and manage undelivered messages Message Tracking & Tracking Log Explorer Use to confirm message delivery Routing Log Viewer Use to view the message routing topology Protocol Logging Use to provide detailed protocol-level information Telnet Use to check if the SMTP port responds or to directly send a SMTP mail to a connector

Demonstration: How to Troubleshoot SMTP Message Delivery In this demonstration, you will see how to: Use Telnet to check if Exchange Server responds correctly Use Queue Viewer to troubleshoot SMTP message delivery

Lesson 2: Configuring Message Transport Process for Configuring Hub Transport Servers Demonstration: How to Configure Hub Transport Servers Options for Configuring Message Transport What Are Accepted Domains? What Are Remote Domains? Demonstration: How to Configure Accepted and Remote Domains What Is an SMTP Connector? Demonstration: How to Configure SMTP Send and Receive Connectors What Is Back Pressure?

Process for Configuring Hub Transport Servers To configure a Hub Transport server: Configure a postmaster mailbox Configure authoritative domains and address policies Configure server-specific settings Configure Internet message flow Configure messaging policies Configure administrative permissions

Demonstration: How to Configure Hub Transport Servers In this demonstration, you will review: Options at the global and server level Default configuration Options for changing the default configuration for Hub Transport servers

Options for Configuring Message Transport Moderated transport Enhanced disclaimers Anti-spam and antivirus protection Rights protection using transport protection rules Transport rules Journaling

What Are Accepted Domains? Accepted domains can be: Internal relay domains Authoritative domains Accepted domains define SMTP domain names for which the Exchange server will accept External relay domains

What Are Remote Domains? Properties of remote domains are: Out-of-office message delivery Remote domains define SMTP domains that are external to your Exchange organization Message format options including acceptable character sets

Demonstration: How to Configure Accepted and Remote Domains In this demonstration, you will review: The default accepted domain configuration How to configure accepted domains How to configure one remote domain

What Is an SMTP Connector? SMTP Receive Connectors: Accept SMTP messages from other hosts Must use a unique combination of port number, listening IP address, and accepted remote IP addresses SMTP connectors are Exchange Server components that support one-way SMTP connections SMTP Send Connectors: Send SMTP messages to other servers Are required to send to any SMTP server

Demonstration: How to Configure SMTP Send and Receive Connectors In this demonstration, you will see how to: Create and configure a SMTP Send connector Create and configure a SMTP Receive connector

What Is Back Pressure? Resource Utilization Level Description Normal The resource is not overused. The server accepts new connections and messages Medium The resource is slightly overused. Back pressure is applied to the server in a limited manner. Mail from senders in the authoritative domain can flow. However, the server rejects new connections and messages from other sources High The resource is severely overused. Full back pressure is applied. All message flow stops, and the server rejects all new connections and messages Back pressure is a system-resource monitoring feature that you can use to: Monitor system resources such as available hard disk, drive space, and memory Restrict new connections and messages if a system resource exceeds a specified level Prevent the server from being completely overwhelmed

Lab: Managing Message Transport Exercise 1: Configuring Internet Message Transport Exercise 2: Troubleshooting Message Transport Exercise 3: Troubleshooting Internet Message Delivery Logon information Estimated time: 60 minutes Virtual machines 10135A-VAN-DC1, 10135A-VAN-EX1, 10135A-VAN-EX2 User nameAdministrator Password Pa$$w0rd

Lab Scenario You are a messaging administrator in A. Datum Corporation, which is a large multinational organization that includes offices in London, Tokyo, and Vancouver, which is its headquarters. Your organization has deployed Exchange Server 2010 in two of its sites. However, all Internet messages should flow through the main site in Vancouver. As part of your job responsibilities, you need to set up the message transport to and from the Internet and also ensure that the message flow works within and between the various sites.

Lab Review What would you need to configure to enable outbound Internet from each of Adatum‘s location? A user calls and reports that she sent a message to a user in another company two hours ago, and the message has not arrived. How would you troubleshoot this? After A. Datum. bought some new locations, you want to make sure that all messages are passed through the main site in Vancouver. How would you do that?
