For new installations, you can use an internal evaluation SQL Server 2008 R2 Express database instance. When selected, the installer will automatically install the database instance with an instance name of “MailExpress” and a database name of “MAILEXPRESS.” The initial Mail Express Server administrator password specified during installation will be used for the “sa” account password. Additionally, the installer will create a database user account for use by the Mail Express Server. The username and password for this account will match the initial Mail Express administrator password.
Only the Database Engine and limited configuration tools are installed. The tools include the "SQL Server Configuration Manager." The following services are installed:
SQL Server (MAILEXPRESS) – The Mail Express Database Instance.
SQL Server Agent (MAILEXPRESS) – This service is disabled by default and not used by Mail Express.
SQL Server Browser – the browser service used to locate the MAILEXPRESS database instance when using dynamic TCP/IP ports.
SQL Server VSS Writer
The Mail Express Server uses Java Database Connectivity (JDBC) and the SQL Server JDBC driver to communicate with the database. This driver uses TCP/IP to connect to the database so the MAILEXPRESS SQL Server database instance is installed with TCP/IP support enabled.
For enhanced security, the TCP/IP settings are configured to listen for connections only from the local computer, using the localhost interface (127.0.0.1). To allow remote connections or to modify the communications settings, use the SQL Server Configuration Manager.
When the internal evaluation database is used, the Mail Express Server installer will automatically create an additional service dependency for the Mail Express Server Windows service on the SQL Server Database instance Windows Service - “SQL Server (MAILEXPRESS).”
