Fully qualified domain address

Fully qualified domain address

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.
