352 Chapter 6 • Managing the Hub Transport Server Role ■ Internet This option is used to create a Receive connector that will receive e-mail from servers on the Internet. This connector will be confi gured to accept connections from anonymous users. ■ Internal Internal Receive connectors are used to receive e-mail from servers within your Exchange organization. Note that this connector type will be confi gured to only accept connections from internal Exchange servers. ■ Client Client Receive connectors are used to receive e-mail from authenticated Exchange users. This means that this connector will be confi gured to only accept client submissions from authenticated Exchange users. ■ Partner Partner Receive connectors are used to receive e-mail from partner domains. This connector will be confi gured to only accept connections from servers Figure 6.29 Selecting the Receive Connector Type Managing the Hub Transport Server Role • Chapter 6 353 that authenticate with Transport Layer Security (TLS) certifi cates for SMTP domains included in the list of domain-secured domains. You can add domains to this list by using the -TLSReceiveDomainSecureList parameter in the Set-TransportConfi g command. 5. When you have selected the type of connector you want to create, click Next. 6. As shown in Figure 6.30, you now have the option of modifying the IP address and port that should be used to receive mail. With Custom, Internet, and Partner Receive connectors, you also have the option of entering a FQDN that should be provided in response to HELO and EHLO commands. When ready, click Next. 7. On the Confi guration Summary page, click New. On the Completion page, click Finish. Figure 6.30 Entering the Local IP Addresses that Should Be Used to Receive Mail 354 Chapter 6 • Managing the Hub Transport Server Role TIP To create a Receive connector via the Exchange Management Shell, you must use the New-ReceiveConnector cmdlet. For example, to create a Receive Connector similar to the one we generated in the previous steps, run the following command: New-ReceiveConnector –Name ‘Special Receive Connector’ –Usage ‘Custom’ –Bindings ‘0.0.0.0:25’ –Fqdn ‘mail.exchangedogfood.dk’ –RemoteIPRanges ‘0.0.0.0– 255.255.255.255’ –Server ‘EDFS03’ At any time, you can modify an existing Receive connector as required. You do this by selecting the respective Receive connector and clicking Properties in the Action pane. In addition, any existing Receive connectors can be disabled, enabled, and removed as necessary. You do this by selecting the particular Receive connector and clicking the required task in the Action pane. Managing Message Size and Recipient Limits Like previous versions of Exchange, Exchange 2007 allows you to restrict the size of messages users can send and receive. The message size limits can be set globally in the organization on a per-server, per-connector level, and/or a per-user basis. Message size and recipient limits can only be confi gured using the Exchange Management Shell. In the following, I’ll show you how to confi gure these limits. Confi guring Global Limits By default, the global limits are set to unlimited, as can be seen in Figure 6.31. Figure 6.31 Listing Global Limits Managing the Hub Transport Server Role • Chapter 6 355 To confi gure new limits that apply to all Exchange 2007 Servers in the organization, you must use the following command: Set-TransportConfi g -MaxReceiveSize:<value> -MaxSendSize:<value> -MaxRecipientEnvelopeLimit:<value> NOTE When you set the MaxReceiveSize or MaxSendSize, it’s important to note that if you only specify a number such as 100, it defaults to kilobytes (KBs). This means that it is generally a good idea to specify the number followed by either KB or MB. Confi guring Server Limits Since message size limits are controlled via Send and Receive connectors, you cannot confi gure message size limits per server. You can, however, confi gure the maximum number of recipients allowed per message. That is, the maximum number of recipients that can be included on a single e-mail message and submitted to the Pickup directory. By default, the maximum number of recipients is 100, which can be verifi ed by running Get-TransportServer | FL in the Exchange Management Shell. To change this setting, you must use the following command: Set-TransportServer -PickupDirectoryMaxRecipientsPerMessage:<value> Confi guring Connector Limits By default, the default maximum message size for both Send and Receive connectors is 10 MB. You can verify this by running Get-SendConnector | FL and Get-ReceiveConnector | FL, respectively. Send Connectors To change the maximum message size limit on a Send connector, use the following command: Set-SendConnector <name of connector> -MaxMessageSize:<value> Receive Connectors To change the maximum message size limit on a Receive connector, use the following command: Set-ReceiveConnector <name of connector> -MaxMessageSize:<value> 356 Chapter 6 • Managing the Hub Transport Server Role Confi guring Per-User Limits You can also confi gure message size limits on a per-user level, if required. Message size limits set on a user override global limits and connector limits. The default message size limit for both sent and received messages on a user mailbox is unlimited, as can be seen by running Get-Mailbox | FL. In order to change this setting, run the following command: Set-Mailbox –MaxReceiveSize:<value> -MaxSendSize:<value> NOTE When you set the MaxMessageSize, it’s important to note that if you only specify a number such as 100, it defaults to kilobytes (KBs). This means that it is generally a good idea to specify the number followed by either KB or MB. NOTE When you set the MaxReceiveSize and MaxSendSize, it’s important to note that if you only specify a number such as 100, it defaults to kilobytes (KBs).

Message Tracking with Exchange Server 2007 When message tracking is enabled, all Simple Mail Transfer Protocol (SMTP) transport activity on all messages that transfer to and from an Exchange 2007 computer with a Hub Transport, Mailbox, or Edge Transport server role installed are recorded into a log, located by default in the C:\Program Files\Microsoft\Exchange Server\TransportRoles\Logs\MessageTracking directory. Message tracking logs can be used for message forensics, mail fl ow analysis, reporting, and troubleshooting. When message tracking is enabled (which is the case by default), the maximum age for message tracking log fi les is 30 days. After 30 days, the oldest message tracking log fi les are deleted using circular logging. This is only true if the message tracking log reaches its specifi ed maximum size (which, by default, is 10 MB), or a message tracking log fi le reaches its specifi ed maximum age. . mail.
