This script updates address space for specific send connectors in Microsoft Exchange Server 2010.
Send connectors create a logical connection to remote e-mail systems and are responsible for outbound transmission of e-mail messages. If your organization requires a Send connector with specific configuration options, or if you don't use the EdgeSync process, you have to manually configure Send connectors. Sometimes, you need to add or remove dozens of domains in the address spaces. So you want a script to complete this task more efficiently.
