Use the Address Space tab on the Send Connector properties dialog box to maintain the list of address spaces for which this Send connector is responsible. You can configure an SMTP address space or a non-SMTP address space. Non-SMTP address spaces may only be configured on Send connectors that exist on Hub Transport servers. If you use a non-SMTP address space type, you must use a smart host to route e-mail.

Add

To specify an address space to which this Send connector will route mail, click Add or the drop-down arrow located next to Add.

• When you click Add, the address space type is always SMTP.
  
  
• When you click the drop-down arrow located next to Add, you can select SMTP Address Space or Custom Address Space.
  
  

On a Hub Transport server or Edge Transport server, if you click Add or the drop-down arrow located next to Add and select SMTP Address Space, enter the following information in the SMTP Address Space dialog box:

• Address   Enter the address space as follows, for example: contoso.com. You can include the wildcard character (*) in the address space as defined in RFC 1035. For example, "*", "*.com", and "*.contoso.com" are permitted, but "*contoso.com" is not permitted.
  
  To also use this connector to route mail to all subdomains of the specified address space, select Include all subdomains. If you entered an address space that contains the wildcard character, Include all subdomains is automatically selected.
  
  
• Cost   Use the address space cost to set the selection priority when more than one Send connector is configured for the same address space. During routing resolution, when the connector selection is made, the least cost routing path to the destination address space is selected. The default cost is set to 1. The valid input range is 1 to 100.
  
  

On a Hub Transport server, if you click the drop-down arrow located next to Add and select Custom Address Space, enter the following information in the Custom Address Space dialog box:

• Type   This field describes the address space that you enter in the Address field. If you enter SMTP or X400 in the Type field, Exchange 2007 monitors the syntax of the address space that you enter in the Address field. If you enter any other text string in the Type field, the Address field becomes free-form text.
  
  
• Address   If you entered SMTP in the Type field, the address space that you enter must be RFC 1035-compliant. For example, "*", "*.com", and "*.contoso.com" are permitted, but "*contoso.com" is not permitted. If you entered X400 in the Type field, the address space that you enter must be RFC 1685-compliant, such as o=MySite;p=MyOrg;a=adatum;c=us. If you enter any other text string in the Type field, you can enter any text for the address space.
  
  
• Cost   Use the address space cost to set the selection priority when more than one Send connector is configured for the same address space. During routing resolution, when the connector selection is made, the least cost routing path to the destination address space is selected. The valid input range is 1 to 100.
  
  

Edit

To modify an existing address space in the address space list, select the address space, and then click Edit.

Remove

To delete the domain name from the list of domains, select a domain name and then click .

Scoped Send connector

By default, all Send connectors that you create can be used by all the Hub Transport servers in the Exchange organization. However, you can limit the scope of any Send connector so that it can be used only by other Hub Transport servers that exist in the same Active Directory site. To limit the scope of the Send connector, select Scoped Send connector.

Apply

To save the changes that you made without closing the dialog box, click Apply.
