unqualified address - Computer Definition
A partial, incomplete address. It may refer to the address of a file, website or e-mail recipient. For example, an e-mail client program that supports unqualified addresses allows users to send e-mail to numerous people in their own company by typing only the recipient's e-mail name, rather than the full address. By setting the company domain name as the unqualified address, when the e-mail client encounters only a recipient name in the To: field, it automatically appends the @ sign and domain to make it a legitimate, "fully qualified" e-mail address. See FQDN and fully qualified.
