In the next window, we need to choose the option – Only when email messages are sent to these domains

The meaning of this option is that in the next step, we will need to define the domain name which will “activate” the Exchange Online send connector.
Every time that Exchange Online recipient will send an E-mail message that includes the specified domain, the Exchange sends connector will be activated.

Click on the plus sign to add the required domain name

In our specific scenario, the “destination domain name” is – fakedomain.com

Notice the interesting fact that, in reality, there are no such domain and Exchange Online will not locate the host who represents this “fake” domain by using the stranded MX record lookup.

Instead, each time that an E-mail message will include this domain name (fakedomain.com) the E-mail will be routed to a designated host described as – smart host, by specifying a particular IP Address.

We will need to uncheck the option – Always use Transport Layer Security (TLS) to secure the connection (recommended).

The reason for – unchecking this option is that most of the time the external FAX service will not support TLS.

Most of the time the recommendation to simplify things in the first phase, meaning – not to implement TLS. Later, if the Exchange Online sends connector will manage to deliver that required mail as we expect, we can go back to the send connector settings and add the requirement for TLS if needed.

In this step, the Exchange Online connector needs to validate the connection to the destination mail infrastructure.

The Exchange Online feature of “validation” is a nice feature, but could be considered as “problematic” sometimes because the need for using the validation process is mandatory.

Even in the case that the validation process fails, we can complete the task of creating the new Exchange send connector.

In simple words- we will need to complete the validation process to be able to complete the creation if the Exchange Online sends connector.
