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 address, domain, fully and/or qualified:

    It wasn’t by accident that the Gettysburg address was so short. The laws of prose writing are as immutable as those of flight, of mathematics, of physics.
    Ernest Hemingway (1899–1961)

    Without metaphor the handling of general concepts such as culture and civilization becomes impossible, and that of disease and disorder is the obvious one for the case in point. Is not crisis itself a concept we owe to Hippocrates? In the social and cultural domain no metaphor is more apt than the pathological one.
    Johan Huizinga (1872–1945)

    No matter what a man does, he is not fully sane or human unless there is a spirit of freedom in him, a soul unconfined by purpose and larger than the practicable world.
    Charles Horton Cooley (1864–1929)

    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)
