Message Mail Flow Architecture ! Intraserver Message Flow ! Outbound Message Flow ! Inbound Message Flow There are several components in Exchange 2000 and Windows 2000 that work together to send and receive messages. These components run on each server running Exchange 2000. After you understand the underlying architecture, you will be able to describe intraserver, outbound, and inbound message flow. Topic Objective To introduce the components and functions of message flow architecture. Lead-in Several Exchange 2000 and Windows 2000 components comprise message flow architecture. Module 9: Message Flow in Microsoft Exchange 2000 3 BETA MATERIALS FOR MICROSOFT CERTIFIED TRAINER PREPARATION PURPOSES ONLY Message Mail Flow Architecture IIS SMTP Advanced Queuing Engine Message Categorizer Routing Information Information Store Store EXIPC Each component of the message flow architecture performs a specific function when sending and receiving messages. Within Exchange, message flow involves routing, queuing, categorizing, and communication between protocols and the Information Store. Information Store The Exchange 2000 Information Store is the end point for messages sent to users with mailboxes on the server running Exchange 2000. The Information Store is also the starting point for messages that are sent by Messaging Application Programming Interface (MAPI) clients, such as Outlook, that connect directly to the Exchange 2000 Information Store. EXIPC The Exchange InterProcess Communication (EXIPC) provides a queuing layer that enables IIS and store processes (Inetinfo.exe and Store.exe) to quickly move data back and forth. The ability to move data quickly is required to achieve the best possible performance between the protocols and database services on a server running Exchange 2000. IIS The client access protocols in Exchange 2000 are part of Internet Information Services (IIS). The IIS process is the protocol engine. Incorporating the protocols into IIS enables you to host Exchange 2000 subsystems (protocol, storage, and directory) on virtual servers on either the same computer or on different computers, which makes Exchange 2000 more scalable. Topic Objective To describe message flow architecture components and functions. Lead-in Managing incoming and outgoing message traffic is important for effective message handling. 4 Module 9: Message Flow in Microsoft Exchange 2000 BETA MATERIALS FOR MICROSOFT CERTIFIED TRAINER PREPARATION PURPOSES ONLY Advanced Queuing Engine The Advanced Queuing Engine defines and manages queues for message delivery, such as domain and link queues that you can query for transport information. When the Advanced Queuing Engine receives an SMTP Mailmsg object, it forwards the Mailmsg object to the Message Categorizer, which returns the message destination. The Advanced Queuing Engine then queues the Mailmsg object for delivery based on the routing information provided by the routing engine. Message Categorizer The Message Categorizer is a plug-in to the Advanced Queuing Engine. It is a collection of event sinks that perform advanced address resolution on every Mailmsg object that travels through the Advanced Queuing Engine. It may also perform bifurcation for messages with two types of recipients, RTF and MIME. Bifurcation creates multiple Mailmsg objects, one for all RTF recipients and the other for all MIME recipients. These messages may be intended for the local information store, a remote host through the message transfer agent (MTA), or a remote host through SMTP. The Message Categorizer is turned off by default in Windows 2000. Installing Exchange 2000 activates the Message Categorizer. Routing The routing engine adds link state routing capabilities by providing accurate next hop information to the Advance Queuing Engine. The routing engine creates and maintains link state information for the server running Exchange 2000. SMTP The SMTP service processes incoming traffic from SMTP clients, such as Microsoft Outlook Express, and other SMTP hosts, such as another Exchange server. Windows 2000 also uses this transport to perform certain operations, such as directory replication in Active Directory.
