Definition: unqualified address


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