Use the Network tab on the Receive Connector Properties dialog box to specify the IP addresses and TCP ports on which this Receive connector receives connections. You can also configure the IP address ranges from which this Receive connector accepts connections.

Note

After you have configured IP addresses and ports for the POP3 or IMAP4 service by using the Exchange Management Console, you must restart either the POP3 or IMAP4 service, depending on which service you are using. For more information about how to restart the IMAP4 service, see How to Start and Stop the IMAP4 Service. For more information about how to restart the POP3 service, see How to Start and Stop the POP3 Service.

Note

If Exchange 2007 SP1 is deployed on a computer that is running the Windows Server 2008 operating system, enter IP addresses and IP address ranges in the Internet Protocol Version 4 (IPv4) format, Internet Protocol Version 6 (IPv6) format, or both formats. A default installation of Windows Server 2008 enables support for IPv4 and IPv6. For more information about Exchange 2007 SP1 support for IPv6 addresses, see IPv6 Support in Exchange 2007 SP1 and SP2.
