To examine the stored messages in MSG File format of Zimbra Server, first, we have to understand the Zimbra Server throughly. Zimbra Server manages complete data like mailbox contents, messages, contacts, calendars, etc. It is supported on Linux operating system only. The MTA Server receives the messages and passes them through a set of created filters. The messages are then finally deposited to the correct mailbox. It is available in both open-source and commercial versions. In the commercial versions, closed-source components like MAPI connector are made available. The MAPI connector enables the user to synchronize Outlook contact and calendar with Zimbra Server.
Zimbra Server can be installed in both single-Server as well as multi-Server environments. When installed in single-user environment, all the services associated with the Server are stored on different disk partitions. However, in multi-Server installation, the LDAP and MTA services are installed on separate Servers.
There are multiple volumes for mailbox Server:
The mailbox messages are stored at the location opt/zimbra/store.
The data store is in the form of SQL database and gets stored in MySQL database files. The storage location of the data store is opt/zimbra/db.
The index files belonging to it are stored at the location opt/zimbra/index.
The Zimbra Server stores its full and incremental backup at the location opt/zimbra/log.
All the components of Zimbra Server have a log file associated with it. They are stored at the location opt/zimbra/log.
It is advised to store the log files and the backup files on different locations of the disk in order to minimize the possibility of data loss due to disk failure.
