We are setting up an environment where we have a shared smtp between 2 exchange organization for migration.

So on each organization we’ll configure a send connector for the SMTP domain.com ( internal relay ) 

To prevent a mail loop for non existent recipient I think a mail flow rule must be created, and I saw some articles that I couldn’t find anymore, to check for the X-headers.

Can anyone help me providing some examples ?

thanks
