The term Administrative Management Domain, more commonly shortened to ADMD, is used in many standards and related publications related to email. It refers to a single entity operating one or more computers within one or more Internet domain names under said entity’s control. One example might be a small company with a single server handling email for that company’s single domain. Or an ADMD might refer to a university operating many servers that fulfill different roles, across different networks, all handling email for several different domains used by different groups within the university.
