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.

Use these local IP Addresses to receive mail

Use this list to specify the IP addresses and port numbers on which this Receive connector listens for incoming mail. For each entry, you must specify a different set of IP addresses or specify all available IP addresses.

To edit an existing IP address, select the IP address, and then click Edit.

To remove an existing IP address, select the IP address and then click .

To add a new IP address or port number, click Add The following options are available in the window that appears:

• Use all IP addresses available on this server   To use all IP addresses that are associated with this computer, select this recommended option.
  
  
• Specify an IP address   Select this option if the following conditions are true:
  
  
  • More than one IP address is associated with the computer.
    
    
  • You want to bind the Receive connector to a specific IP address.
    
    
  Then, in the text box, type the IP address on which this Receive connector accepts connections.
  
  

  Note:
  You must specify a local IP address that is valid for the Hub Transport server or Edge Transport server on which the Receive connector is located. If you specify an invalid local IP address, the Microsoft Exchange Transport service may fail to start when the service is restarted.

• Port   This field identifies the TCP port number on which this Receive connector listens for incoming mail. TCP port 25 is the default port that is used for message transmission between Simple Mail Transfer Protocol (SMTP) messaging servers.
  
  

Receive mail from remote servers which have these IP addresses

Use this list to specify the IP address or IP address range from which this Receive connector accepts connections. To add the remote IP address or remote IP address range, use one of the following methods:

• To enter an IP address or subnet without a subnet mask, or to specify the subnet mask by using Classless Interdomain Routing (CIDR) notation, click Add or the drop-down arrow located next to Add and select IP Address. In the Add IP address(es) of Remote Servers dialog box, enter the IP address by using one of the following methods:
  
  
  • IP address without a subnet mask   For example, 192.168.1.0. If you don't specify a subnet mask by using CIDR notation, the classful default subnet mask is assumed.
    
    
  • IP address by using CIDR notation   For example, 192.168.1.0/24
    
    
• To enter an IP address or subnet together with a subnet mask in dotted decimal notation, click the drop-down arrow located next to Add and select IP and Mask. In the Add Remote Servers - IP and Mask dialog box, enter the IP address and the subnet mask by using the following syntax:
  
  
  • IP Address   For example, 192.168.1.0
    
    
  • Subnet Mask   For example, 255.255.255.0
    
    
• To specify an IP address range by using the first IP address and the last IP address in the range, click the drop-down arrow located next to Add and select IP Range. In the Add Remote Servers - IP Range dialog box, enter the IP address and the subnet mask by using the following syntax:
  
  
  • Start Address   For example, 192.168.1.1
    
    
  • End Address   For example, 192.168.255.255
    
    
  Because you can't specify a subnet mask, the classful default subnet mask is assumed.
  
  

To edit an existing IP address range, select the IP address range, and then click Edit.

To remove an existing IP address range, select the IP address range, and then click .
