    One SMTP server find another SMTP server by querying DNS for the MX record
    of the domain which appears after the @ symbol in an email address. For
    example, you want to send an email to . Well, your
    SMTP server will then query a DNS server inside the microsoft.com zone for
    an MX record to which it will send the email.
