The ContentStore Mailbox provides SMTP-based journaling. Journaled messages are sent from any mail server to an external recipient using the SMTP protocol. In this case, the external recipient is a mailbox on the Commvault ContentStore Mail Server (SMTP).
The journaled messages are stored as messages on the ContentStore Mail Server (SMTP). After the messages are archived, you can run a cleanup job to delete the messages from the SMTP server. When journaled messages are restored, they are restored as .eml files.
If the CommServe computer is offline, the ContentStore Mailbox continues to receive messages. The messages are not held in a queue on the Exchange server.
Note
You must use ContentStore Mailbox and configure journaling for Exchange 2019 servers.

ContentStore Mailbox supports Envelope Journaling & Non-envelope journaling.
Envelope Journaling
Envelope journaling sends a copy of the email as an email attachment. The original email becomes an attachment, and the sender, the recipients (To/Cc/Bcc), and the message-Id move to the message body.The ContentStore Mailbox can capture BCC and distribution list information if the sending mail server has envelope journaling enabled. This information is not captured if envelope journaling is not enabled. Any type of mailing servers is supported if it provides the envelope format.
ContentStore Mailbox supports envelope journaling and non-envelope journaling.
Consult the documentation for your mail server to determine how to enable journaling for your mail server.
The ContentStore Mailbox will capture all other information if envelope journaling is not enabled.
Non-Envelope Journaling
Non-Envelope journaling sends a copy of the email as you would see in a mail client. The ContentStore Mailbox does not capture the BCC and the distribution list information.
The ContentStore Mailbox will capture all other information if envelope journaling is not enabled.
ContentStore Mailbox supports envelope journaling and non-envelope journaling.
Load Balancing and Fault Tolerance
The ContentStore Mailbox supports the following methods for load balancing:
-
Deploying a single send connector with multiple smart hosts
-
Hardware load balancers
-
Mail exchange records (MX records)
The method that you choose depends on your environment.
