1. Module 5 Managing Message Transport

2. Module Overview Overview of Message Transport Configuring Message Transport

3. Lesson 1: Overview of Message Transport 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

4. Components of Message Transport Submission queue Exchange Mail Submission service SMTP Receive connecter Pickup and Replay directories Agent delivery Agent delivery Remote delivery queue Mailbox delivery queue Categorizer Store driver Store driver SMTP Send connector User mailbox Hub Transport server Mailbox server Deliver to Inbox Submit from Outbox

5. How Are Messages Routed in an Exchange Server Organization? Internet Hub Transport server Mailbox server Outlook client Client Access server 3 3 2 2 1 1 6 6 5 5 4 4

6. How Are Messages Routed Between Active Directory Sites? 20 10 Default message flow Source Site Destination Site 10 Delayed fan-out Queue at the point of failure 20 10 Default message flow Source site Destination site 10

7. 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

8. 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 TestExchange Connectivity Website Use to test connectivity to Exchange services from outside

9. 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

11. Lesson 2: Configuring Message Transport Process for Configuring Hub Transport Servers Demonstration: How to Configure Hub Transport Servers 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?

12. Process for Configuring Hub Transport Servers To configure a Hub Transport server: Configure a postmaster mailbox Configure authoritative domains and email address policies Configure server-specific settings Configure Internet message flow Configure messaging policies Configure administrative permissions 1 1 2 2 3 3 4 4 5 5 6 6

13. 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

14. 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 email External relay domains

15. 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

16. 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

17. 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 email to any SMTP server

18. 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

20. 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

21. 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

22. 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.

23. Lab Review What would you need to configure to enable outbound Internet email 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 email messages are passed through the main site in Vancouver. How would you do that?
