What is SMTP send connector?
SMTP Send connectors are used to route mail between Hub Transport servers in your Active Directory site. Send connectors created on servers with the Hub Transport role installed are stored in Active Directory. These Send connectors are then made available to all Hub Transport role servers in the organization.
What does a send connector do?
The Send connector routes mail to recipients in the specified domain, and in all subdomains. The Send connector routes mail to recipients in all accepted domains in the Exchange organization. This value is only available on Send connectors on Edge Transport servers that send mail to the internal Exchange organization.
How does Exchange choose Send connector?
When Exchange selects a connector for routing a message, it only considers connectors that have a matching address space. If more than one connector matches the destination address space, the connector with the more precise address match is selected. By default, the address space type on a new Send connector is SMTP.
What is a connector in email?
Connectors enable mail flow in both directions (to and from Microsoft 365 or Office 365). You can enable mail flow with any SMTP server (for example, Microsoft Exchange or a third-party email server). When email is sent between John and Bob, connectors are needed.

What is Exchange 2010 Send connector?
Send Connector allows you to send emails from your Exchange server to other domains out on the Internet. When you install Exchange 2010, receive connector is created automatically by default.
What are send and receive connectors?
Receive connectors control incoming SMTP mail flow. They listen for incoming connections that match the configuration of the connector. Send connectors control outgoing SMTP mail flow. A Send connector is chosen based on the message recipients and the configuration of the connector.
What is Relay in SMTP?
SMTP relay services allow businesses to send email without using their own servers or domain so that marketing messages can be separated from internal email communications. Email client software such as Outlook or Thunderbird provides a graphical interface for users to work with SMTP relay.

The usage type is Custom. The Send connector uses smart host routing (the DNSRoutingEnabled parameter is set to the value $false). The smart host’s IP address is 192.168.3.2, and the authentication method is None, because the smart host is configured to listen for connections only from a restricted list of source servers.
