Starts Database Mail by starting the Service Broker objects that the external program uses.
Database Mail is not enabled or installed upon SQL Server installation. Use the Database Mail Configuration wizard to enable and install the Database Mail objects.
This stored procedure is in the msdb database. This stored procedure starts the Database Mail queue that holds outgoing message requests and enables the Service Broker activation for the external program.
When the queues are started, the Database Mail external program can process messages. This procedure allows you to restart the queues after the queues have been stopped with the sysmail_stop_sp stored procedure.
This stored procedure only starts the queues for Database Mail. This stored procedure does not activate Service Broker message delivery in the database.
The following example shows starting Database Mail in the msdb database. The example assumes that Database Mail has been enabled.
USE msdb ; GO EXECUTE dbo.sysmail_start_sp ; GO
