Microsoft decided that it was best if administrators took a deliberate step to configure connectors if they wanted to support anonymous connections on hub transport servers and this is how Exchange 2007 and Exchange 2010 operate. Things are different on Edge servers. In this case, the Edge server role is explicitly designed to accept and process incoming messages from external servers, so it wouldn t make sense if its connectors forced authenticated connections. You can update the connector by selecting the Anonymous Users check box in the Permission Group Properties dialog box, as shown in Figure 13-8, or with EMS:

Remember that receive connectors are scoped to a single server, so if you apply this change to the default receive connector on one hub transport server, you should apply it to all the hub transport servers that are active across the organization. If you don t configure a receive connector to allow anonymous connections, users who send messages from the other email systems will receive nondelivery notifications with an error code of 5.7.1, which means that the sending server was unable to authenticate itself and so the connection was terminated by the hub transport server. If some hub transport servers allow anonymous connections and others don t, you can find yourself in a situation where messages presented at one connector will be accepted whereas they will fail if routed to another connector an unacceptable situation for a messaging system. Figure 13-8 shows the nondelivery notification generated by an Exchange 2010 organization for a message that it couldn t deliver to a user in another Exchange 2010 organization. In this case, the essential clue is the 5.7.1 Client Was Not Authenticated line in the diagnostic information at the bottom of the message.

Updating the default receive connector to allow anonymous connections is the easy solution to the problem of accepting incoming messages from external SMTP servers . However, this approach means that you use the same configuration for internal and external messages . You might want to treat external messages differently; for instance, you might allow users to send 10 MB messages internally but want to restrict incoming messages to 5 MB . In this circumstance, it is best practice to create one or more dedicated receive connectors to process intranet SMTP traffic and then customize these connectors with appropriate message size limits and to allow anonymous connections . You can then direct internal SMTP traffic for the Exchange organization to the servers that host the receive connectors .

Before you create a new receive connector, you need to understand why it is required and what additional functionality it will provide to the organization over and above that available through the default receive connectors that Exchange creates on all hub transport servers. The questions that you might ask include the following:
1. What hub transport server will host the new connector 2. What function does the new connector serve Will it connect two internal Exchange
organizations, handle other internal SMTP traffic, connect Exchange 2010 to Exchange 2003, or have another use
3. What special settings such as the maximum size of inbound messages apply to the
connector
4. What permissions are necessary for clients who will use the receive connector
Once these answers are clear, you can proceed to the Server Configuration section of EMC. Select the Hub Transport node, then the server that will host the new connector, and then select the New Receive Connector option. EMC launches the New Receive Connector Wizard and asks you to name the new connector and select its purpose from a drop-down list (Figure 13-9).

The selected purpose determines the permission groups and other settings that Exchange applies to the new connector and can be any of the following:
Custom: Allows the greatest flexibility in the use of the connector. A connector of this type can be used for many purposes, including cross-forest connections and connections to other SMTP-based mail systems that operate within the firewall. Internet: Used to allow unencumbered connections from external SMTP servers. This setting is used by Edge transport servers and should not be used for intranet connections. Internal: Used for connections between this Exchange organization and other Exchange organizations that operate within the firewall. Client: Used to support POP3 and IMAP4 client connections. Partner: Used for TLS-secured connections with specified partner domains (see the discussion in the section TLS security earlier in this chapter).
For our purposes, we want to create a new receive connector to handle incoming messages generated by a Linux-based Sendmail system. We don t need to create a specific connector for this purpose, because it would be possible to amend the properties of a default receive connector on a hub transport server to accept anonymous connections, as discussed earlier, and point the Sendmail system to this server as its entry point to the Exchange organization. However, having a dedicated connector allows more control over the messaging flow
