Setting Up Connection with the Target Exchange Organization Using SMTP Connectors

This section describes how to set up a connection with the target Exchange organization using SMTP connectors. On this step you may need to coordinate with the administrator of the target Exchange organization to set up the connection properly.

Setting up Source Exchange Organization for Internet Mail Flow between Source and Target Exchange Organizations

You need to establish Internet mail flow between the source and the target Exchange organizations. For that, you need to create an Internet Send connector and Receive connector on an Exchange Mailbox server that can be directly reached through the Internet.

To establish mail flow to and from the Internet through a Mailbox server, follow these steps:

  1. Create a Send connector (to send email from source Exchange organization to the Internet) on the Mailbox server.
  2. Modify the default Receive connector for the source domain to accept anonymous e-mail from the Internet
  3. Add the e-mail domain used for redirection to the list of accepted domains.

Each step is explained in further detail in the related subtopics.

Creating Send Connector

To create a Send connector, you can use either Exchange Admin Center (EAC) or Exchange Management Shell.

NOTE: For additional information, refer to the Create a Send Connector for Email Sent to the Internet TechNet article.

To create a Send connector using Exchange Admin Center

  1. In the Exchange Admin Center, navigate to Mail flow > Send connectors, and then click Add +.
  2. In the New send connector wizard, specify a name for the send connector, for example, QMM Send Connector, and then select Custom for the Type. Click Next.
  3. Verify that MX record associated with recipient domain is selected. Then select the Use the external DNS lookup settings on servers with transport roles. Click Next.
  4. Under Address space, click Add +. In the Add domain window, make sure SMTP is listed as the Type. For Fully Qualified Domain Name (FQDN), specify the address space you want to use for mail redirection from source to target organization (for example, *.target.local). Click Save.
  5. Make sure Scoped send connector is not selected, and then click Next.
  6. For Source server, click Add +. In the Select a Server window, select one or more Mailbox servers in your organization and click Add. After you've selected the server, click OK.
  7. Click Finish.

To create a Send connector using Exchange Management Shell

Run the following command:

new-SendConnector -Name 'QMM Send Connector' -Usage 'Custom' -AddressSpaces 'SMTP:*.target.local;1' -IsScopedConnector $false -DNSRoutingEnabled $true -UseExternalDNSServersEnabled $true -SourceTransportServers 'ServerName'

where:

  • *.target.local is the address space you want to use for mail redirection from source to target organization.
  • ServerName is the Mailbox server name.

Modifying Default Receive Connector

To modify the default Receive connector for the source Exchange organization to receive mail from the Internet, you can use either Exchange Admin Center or Exchange Management Shell.

To modify the default Receive connector using Exchange Admin Center

  1. In the Exchange Admin Center, navigate to Mail flow > Receive connectors.
  2. Select the appropriate Mailbox server from the list of servers.
  3. Then select the Default <Server Name> connector and click Edit.
  4. In the Default <Server Name> window, go to Security.
  5. In Permission groups, select Anonymous users to add anonymous permissions.
  6. Click Save.

To modify the default Receive connector using Exchange Management Shell

Run the following command:

Set-ReceiveConnector -PermissionGroups 'AnonymousUsers, ExchangeUsers, ExchangeServers, ExchangeLegacyServers' -Identity 'ServerName\Default ServerName'

Where ServerName is the Mailbox server name.
