How to Configure Send Connector in Exchange Server 2010

As exchange server enables to send and receive e-mails. When a user sends mails then Exchange requires some set of instructions that facilitate to determine message route and delivers the e-mail to the receiver. So here I am giving you a detailed discussion what is Send Connector? How send connector works? How it is interlinked with Hub server and Edge server? And also giving you an optimal way to configure Send Connector.

What is Send Connector?

Send connector generates a logical connection between sender and receiver which facilitate in transmission of remote e-mail messages to the specified receiver. It is configured on mailbox server that runs the Transport services, commonly user configures send connector to send outbound email messages to a smart host or directly to their recipient using DNS (Domain Name Server). The created Send Connectors are stored in active directory and available for all Mailbox Servers running the Transport Service in the organization.

As I stated that Send Connector controls the flow of outbound messages, to control the flow of outbound messages it requires a proper synchronization between Hub Transport Server and Edge Transport Server. Let's discuss about these terms and their functionality.

What is Hub Transport Server?

Hub Transport Server is deployed inside your active directory. It handles all mail flow inside the organization, applies journaling policies, applies transport rule and delivers the mail to the recipients Mailbox. You must have at least one Hub Transport Server to enable internal mail routing and delivery.

What is Edge Transport Server?

Exchange Server environment needs to relay on all inbound and outbound internet mail flow to relay for every mail Exchange Server host a smart host service called Edge Transport Server. Edge Transport Server contains many independent agents that are running on Edge Transport Server provides an additional layer of message protection and security. These agents provide protection against viruses, spam and apply control rules to control mail flow.

How Send Connector Works?

Send connector synchronized with Hub Transport Server and Edge Transport Server and enables a user to send the mail over network. Hub transport server takes message through SMTP submission from pick up directory, applies all message transport rules and transfer to Edge Transport Server. It gathers full information about recipient and then a virtual connection stablish between sender and receiver.

Here I am giving you a way to create Send Connector in Exchange Server 2010 just follow some easy and quick steps which is given below.

This command will create a Send Connector with following settings.

  • Custom connector type is used.
  • Connector sends message to SMTP address space and all sub domain.
  • E-mail is routed through a smart Host with IP address .
  • Maximum size of message is 20 MB is allowed to send.


I have discussed all the related terms and tries to give a generalized view and an efficient way to configure Send Connector. I hope this blog will resolve your problem and make better understanding to all the terms that i have disscissed in this artical.
