Can multiple mail servers be specified for one domain?

Question

Unity

Good afternoon!
Wikipedia says that,

For one domain, several mail servers with different priorities can be specified

.
Question: I have sending via gmail on my domain , so there are MX records for gmail. But I'm missing this and want to additionally use mailgun without unbinding gmail . What do i do? All mail works through gmail , but there is a functionality that should send 5,000 letters at a time, for this I want to bind mailgun how to deal with MX records, and how will this be displayed on mailboxes that are already used by gmail ? Or is it necessary to register on mailgun as a subdomain

Answer 1

void Update()
    {
        Ray ray = Camera.main.ScreenPointToRay(Input.mousePosition); // поле зрение камеры
        RaycastHit hit = new RaycastHit(); // хранит данные объекта с котором пересекся вектор камеры и параметры пересечения
        if (Physics.Raycast(ray, out hit)) // выполняется если хоть один объект встретился
        {
            Vector3 rot = transform.eulerAngles; // запись предыдущего угла Эйлера "Rotation"
            transform.LookAt(hit.point); // перевод в угол поворота из полученных координат при пересечении с объектом
            transform.eulerAngles = new Vector3(0, transform.eulerAngles.y, 0); // установка нового угла
        }
    }

"server" here - a piece of iron with wires
not a domain
as you like - it won't work, or gmail, or your own server

Answer 3

MX records have absolutely nothing to do with this task. The MX record specifies the address of the server that receives mail for this domain. The priority here is a number that specifies the order in which servers are viewed, if there are several of them. If there are records

nichego.net. IN MX 10 test1
            IN MX 20 test2
test1    IN A 1.2.3.4
test2    IN A 1.3.4.5

then when sending a letter to [email protected] your server will first try to connect to test1.nichego.net, if test1 does not accept the connection, then it will turn to test2.nichego.net. If test1.nichego.net is running, then test2.nichego.net will not be accessed. This design is usually used to reserve mail.
