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 a good play every speech should be as fully flavoured as a nut or apple.”
—J.M. (John Millington)
“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)
“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)
“I believe the alphabet is no longer considered an essential piece of equipment for traveling through life. In my day it was the keystone to knowledge. You learned the alphabet as you learned to count to ten, as you learned “Now I lay me” and the Lord’s Prayer and your father’s and mother’s name and address and telephone number, all in case you were lost.”
—Eudora Welty (b. 1909)
