Recipient Policies What Are They?
Recipient policies are organisation wide objects held in the “Recipient Policies” container – a sub container of Recipients. When you install Exchange the program creates a default policy and you can then create as many policies as you want to after. Although you must keep the default policy and you cannot delete it.
What do they do?
Set a default value for the domain used by Exchange to reference files via IFS. (IFS provides access to the Exchange information store by using Win32 file system APIs)Generates email proxy address. RUS generates and sets email addresses on new mail enabled objects but you define the format for the addresses and the type of proxy address that RUS generates through policy.Controls how the mailbox manager processes mailboxes.
Enables SMTP virtual servers to accept incoming mail. When you make an installation of Exchange the virtual servers will accept email from the domain defined in the default policy, but you add policies to cover additional domains if you require.
The Recipient Update Service (RUS) is responsible for creating and maintaining E-Mail Addresses in your Exchange Organization. The Recipient Update Service creates an Entry (Recipient Update Service (Enterprise Configuration)) for the entire Exchange Organization for modifying objects in the Configuration Container Partition in Active Directory and one RUS for every Exchange enabled Domain in this Forest.
Exchange Install.After install there is one default policy created called “Default Policy” This policy contains Proxy address for the default SMTP domain and one for X.400 – You can add additional Proxy addresses to the default policy or have different Recipient Policies for different users.Note:If you want to remove old or unwanted E-Mail addresses, you must either remove the addresses manually in Active Directory Users and Computers or use an automated process. Or you can use LDIFDE.
