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)
“Don’t give your opinions about Art and the Purpose of Life. They are of little interest and, anyway, you can’t express them. Don’t analyse yourself. Give the relevant facts and let your readers make their own judgments. Stick to your story. It is not the most important subject in history but it is one about which you are uniquely qualified to speak.”
—Evelyn Waugh (1903–1966)
“No domain of nature is quite closed to man at all times.”
—Henry David Thoreau (1817–1862)
“The English, the plain English, of the politest address of a gentleman to a lady is, “I am now, dear Madam, your humble servant: Pray be so good as to let me be your Lord and Master.””
—Samuel Richardson (1689–1761)
