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:
“Every man supposes himself not to be fully understood; and if there is any truth in him, if he rests at last on the divine soul, I see not how it could be otherwise. The last chamber, the last closet, he must feel was never opened; there is always a residuum unknown, unanalyzable. That is, every man believes that he has greater possibility.”
—Ralph Waldo Emerson (1803–1882)
“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)
“When it had long since outgrown his purely medical implications and become a world movement which penetrated into every field of science and every domain of the intellect: literature, the history of art, religion and prehistory; mythology, folklore, pedagogy, and what not.”
—Thomas Mann (1875–1955)
“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)
