The original location of the message store is defined when creating the NMAP Agent. This is the default message store for all users in the NMAP Agent's assigned contexts.
NOTE: For a complete discussion of the structure and contents of the message store, see Message Store Directory Structure. For more information on the NMAP Agent's message store property, see the Message Store property in Configuring the NMAP Agent .
Locating all the users' mailboxes in a single message store works well within single organizations; however, when hosting domains for multiple organizations, using a single message store makes it difficult to identify which mailboxes belong to each domain. Creating different message store directories for each domain allows you to easily identify and manage resources for a specific domain.
You can define domain-specific message stores using Container objects.
When NetMail is installed, Container objects take on NetMail properties. The Container object's NetMail Options property includes an option to define a custom message store for users within the current container.
The Container object message store is the volume and directory where the mailboxes for users in the current container are located. It does not affect the general message queue and SCMS directories, which are always located in the default message store volume and directory.
To define a domain-specific message store using Container objects, you would put all the domain's User objects in a single container and then define a Container object message store.
