    Maybe first paragraph of wikipedia's entry will help

    A mail exchanger record (MX record) is a type of resource record in the Domain Name System that specifies a mail server responsible for accepting email messages on behalf of a recipient's domain and a preference value used to prioritize mail delivery if multiple mail servers are available. The set of MX records of a domain name specifies how email should be routed with the Simple Mail Transfer Protocol.

    So, MX records specify which server is responsible for a domain.

    On the side of the receiving server you don't need to specify a MX record, but only domain name and you have to allow connection from the internet.

    Once that is done you have

    • MX record which allows any mail server to know where to route mail (to which server)
    • a receiving server which accepts the mail

    Result is that mail is delivered.
