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:

    When a strong man, fully armed, guards his castle, his property is safe. But when one stronger than he attacks him and overpowers him, he takes away his armor in which he trusted and divides his plunder.
    Bible: New Testament, Luke 11:21.22.

    I used to join the murmurings about “Where are the qualified women?” As we murmured, we would all gaze about the room, up toward the chandelier, into the corner behind the potted palm, under the napkin, hoping perhaps that qualified women would pop out like leprechauns.
    Jane O’Reilly, U.S. feminist and humorist. The Girl I Left Behind, ch. 5 (1980)

    While you are divided from us by geographical lines, which are imaginary, and by a language which is not the same, you have not come to an alien people or land. In the realm of the heart, in the domain of the mind, there are no geographical lines dividing the nations.
    Anna Howard Shaw (1847–1919)

    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)
