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:

    A man who doesn’t drink is not, in my opinion, fully a man.
    Anton Pavlovich Chekhov (1860–1904)

    It has been from Age to Age an Affectation to love the Pleasure of Solitude, among those who cannot possibly be supposed qualified for passing Life in that Manner.
    Richard Steele (1672–1729)

    The vice named surrealism is the immoderate and impassioned use of the stupefacient image or rather of the uncontrolled provocation of the image for its own sake and for the element of unpredictable perturbation and of metamorphosis which it introduces into the domain of representation; for each image on each occasion forces you to revise the entire Universe.
    Louis Aragon (1897–1982)

    Another success is the post-office, with its educating energy augmented by cheapness and guarded by a certain religious sentiment in mankind; so that the power of a wafer or a drop of wax or gluten to guard a letter, as it flies over sea over land and comes to its address as if a battalion of artillery brought it, I look upon as a fine meter of civilization.
    Ralph Waldo Emerson (1803–1882)
