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:
“Cash-payment never was, or could except for a few years be, the union-bond of man to man. Cash never yet paid one man fully his deserts to another; nor could it, nor can it, now or henceforth to the end of the world.”
—Thomas Carlyle (1795–1881)
“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)
“No domain of nature is quite closed to man at all times.”
—Henry David Thoreau (1817–1862)
“Take a red book called TELEPHONE,
size eight by four. There it sits.
My red book, name, address and number.
These are all people that I somehow own.
Yet some of these names are counterfeit.”
—Anne Sexton (1928–1974)
