Fully Qualified Domain Address

A fully qualified domain address (FQDA) is a string forming an Internet e-mail address. It was defined by the Internet Engineering Task Force in RFC 3801 for the use in voice profiles for Internet mail, but has been used on the Internet as early as 1988.

A FQDA is composed of a local part, followed by the symbol @ and the fully qualified domain name (FQDN) of the host responsible for a mailbox.

An example of a FQDA is: localpart@mailhost.example.com. The local part usually denotes a username, while the fully qualified domain name is used by mail transfer agents to determine the IP address of the host by querying the Domain Name System.

Famous quotes containing the words fully, qualified, domain and/or address:

    “... in doing our psychology, we want to attribute mental states fully opaquely because it’s the fully opaque reading which tells us what the agent has in mind, and it’s what the agent has in mind that causes his behavior.”

    “Let’s face it. With the singular exception of breast-feeding, there is nothing about infant care that a mother is innately better qualified to do than a father. Yet we continue to unconsciously perpetuate the myth that men just don’t have what it takes to be true partners in the process.”
    —Michael K. Meyerhoff (20th century)

    “You are the harvest and not the reaper
    And of your domain another is the keeper.”
