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 address, domain, fully and/or qualified:

    Give a boy address and accomplishments and you give him the mastery of palaces and fortunes where he goes.
    Ralph Waldo Emerson (1803–1882)

    No domain of nature is quite closed to man at all times.
    Henry David Thoreau (1817–1862)

    ... it is an uneasy lot at best, to be what we call highly taught and yet not to enjoy: to be present at this great spectacle of life and never to be liberated from a small hungry shivering self—never to be fully possessed by the glory we behold, never to have our consciousness rapturously transformed into the vividness of a thought, the ardour of a passion, the energy of an action, but always to be scholarly and uninspired, ambitious and timid, scrupulous and dim-sighted.
    George Eliot [Mary Ann (or Marian)

    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)
