Mailgun Routes catches the incoming email and makes a POST Request to http://www.yourhelpdeskdomain.com/api/v1/mg/receive
Your help desk instance handles the Mailgun Post Request and routes the incoming message to the appropriate conversation, on the appropriate mailbox.
Note: By default, Full Help will use your current system domain as your Mailgun inbound domian. For example, if your system is accessible on desk.mycompany.com, your Mailgun inbound email will be mycompany.com. If you want to use a different domain as your mailgun domain (e.g., mg.mycompany.com), define it in the .env file: MAIL_FORWARD_DOMAIN=mg.mycompany.com.
