Fully qualified domain address
From Wikipedia, the free encyclopedia
FQDA (Fully Qualified Domain Address) is a string forming the Internet e-mail address comprising the local part, symbol @ and the domain name (e.g. bob@b.org). The local part usually denotes the username, while the domain name is used by Mail transfer agents to find in the Domain Name System the mail exchange servers accepting messages for that domain.
The FQDA is defined in RFC 2822.
