In Exchange Server 2007, you can create multiple Receive Connectors with the same
IP address and port; however, the remote IP range must be unique.
On a Hub Transport server, two Receive Connectors are created by default as shown in Figure 7-10. The
bindings indicate that the Receive Connectors are configured to listen on all IP addresses on available
network adapters on the server and on the designated ports. The Default Receive Connector is configured
to listen on port 25 while the Client Receive Connector listens on port 587. The Client Receive Connector
accepts SMTP connections from all non - MAPI clients, such as POP and IMAP. To view all the properties
on both Receive Connectors, use the Format-List cmdlet in addition to the Get-ReceiveConnector
cmdlet. A basic difference between both connectors besides the bindings is the permissiongroups
attribute also shown in Figure 7 - 10 . This makes sense because only non - MAPI clients connect to the
Client Receive Connector.
Figure 7-10
As mentioned earlier, to create a new Receive Connector, use the New-ReceiveConnector cmdlet. The
Name, Bindings, and RemoteIPRanges are required parameters. You can create a Receive Connector
based on its intended use. The following switch parameters, Custom , Client , Partner , Internal , and
Internet , indicate the types of Receive Connectors that can be created in Exchange Server 2007.
