How to Configure IP Addresses and Ports for POP3 and IMAP4 Access

 

Applies to: Exchange Server 2007 SP3, Exchange Server 2007 SP2, Exchange Server 2007 SP1, Exchange Server 2007

Topic Last Modified: 2007-08-23

This topic explains how to use the Exchange Management Console and the Exchange Management Shell to configure Microsoft Exchange to use ports other than the default ports on the Microsoft Exchange Server 2007 computer that has the Post Office Protocol version 3 (POP3) and Internet Message Access Protocol version 4rev1 (IMAP4) services enabled. In the original release (RTM) version of Exchange 2007, you could only configure IP addresses and ports for POP3 and IMAP4 access by using the Exchange Management Shell. In Exchange Server 2007 Service Pack 1 (SP1), you can also configure IP addresses and ports for POP3 and IMAP4 access by using the Exchange Management Console. Steps for doing this are included in this topic.

noteNote:
If Exchange 2007 SP1 is deployed on a computer that is running Windows Server 2008, 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.
noteNote:
After you configure IP addresses and ports for POP3 and IMAP4 access, you must restart the POP3 or IMAP4 service. For more information about how to restart the POP3 and IMAP4 services, see How to Start and Stop the POP3 Service and How to Start and Stop the IMAP4 Service.

To perform this procedure, the account you use must be delegated the Exchange Server Administrator role and membership in the local Administrators group for the target server.

For more information about permissions, delegating roles, and the rights that are required to administer Exchange, see Permission Considerations.

  1. In the console tree, expand Server Configuration, and then click Client Access.

  2. In the work pane, click the POP3 and IMAP4 tab.

  3. Select either POP3 or IMAP4, and then click Properties in the action pane.

  4. On the Binding tab, under TLS or Unencrypted Connections, click Add.

  5. On the TLS or Unencrypted Connection Settings page, under IP address to use, choose from the following:

    • To use all available IP addresses for a server, select the Use all IP addresses available on this server option.

    • To manually specify an address, select Specify an IP address, and then enter an IP address in the dialog box.

  6. Under Port to Use, in the box next to Port, enter a port number, or accept the default port.

  7. Click OK to save your changes.

  • To set the IP address and port for communicating with Exchange by using POP3 with Secure Sockets Layer (SSL), run the following command:

    Set-PopSettings -SSLBindings: IPaddress:Port
    
  • To set the IP address and port for communicating with Exchange by using POP3 with no encryption or Transport Layer Security (TLS) encryption, run the following command:

    Set-PopSettings -UnencryptedOrTLS Bindings IPaddress:Port
    
  • To set the IP address and port for communicating with Exchange by using IMAP4, run the following command:

    Set-ImapSettings -SSLBindings: IPaddress:Port
    
  • To set the IP address and port for communicating with Exchange by using IMAP4 with no encryption or TLS encryption, run the following command:

    Set-ImapSettings -UnencryptedOrTLSBindings IPaddress:Port
