Recipient policies are used on objects typically thought of as user-side, such as users, groups, and contacts. Exchange includes a single recipient policy used to automatically generate e-mail addresses for mail-enabled Exchange objects such as users, groups, contacts, public folders, stores, and system attendants.
A recipient policy is a setting applied to a set of recipients produced by Lightweight Directory Access Protocol (LDAP) filter; for example, an LDAP filter selecting only users can automatically generate cc:Mail, Microsoft Mail, Simple Mail Transfer Protocol (SMTP), Lotus Notes, and X.400 addresses for those users. Once in place, these addresses make it possible for the users of your Exchange system to communicate with users of non-Exchange systems.
Recipient policies use a background apply implementation to effect configuration changes. An administrator creates a policy, defines the settings that policy implements, and associates that policy with one or more objects using the Exchange LDAP query engine. The policy is applied at a later time based on the schedule of the Address List Service running under System Attendant.
Multiple SMTP and X.400 addresses can be generated by adding them to the policy and applying it to the recipient. This is useful for organizations that have different divisions, are in different regions or countries, or use different e-mail systems; for example, an organization can add SMTP addresses that include the division name to the default address, such as email@example.com and apply that policy to the LDAP query that produces a list of all users in that division.
