Use the EAC to create a Send connector to send email to a partner, with TLS applied
To create a Send connector for this scenario, log in to the EAC and perform the following steps:
- In the EAC, navigate to Mail flow > Send
connectors, and then click Add .
- In the New send connector wizard, specify a name for the
send connector and then select Partner for the Type.
When you select Partner, the connector is configured to
allow connections only to servers that authenticate with TLS
certificates. Click Next.
- Verify that MX record associated with recipient domain
is selected, which specifies that the connector uses the domain
name system (DNS) to route mail. Click Next.
- Under Address space, click Add . In the Add domain window, make sure SMTP is
listed as the Type. For Fully Qualified Domain Name
(FQDN), enter the name of your partner domain. Click
- For Source server, click Add . In the Select a server window, select a Mailbox
server that will be used to send mail to the Internet via the
Client Access server and click Add . After you've selected the server, click Add
. Click OK.
- Click Finish.
Once you have created the Send connector, it appears in the Send connector list.
How do you know this worked?
To verify that you have successfully created a Send connector to send email to a partner, with TLS applied, send a message from a user in your organization to a recipient at the partner organization. If the recipient receives the message, the connector was created successfully.
