Database Mail XPs Server Configuration Option
Use the DatabaseMail XPs option to enable Database Mail on this server. The possible values are:
0 indicating Database Mail is not available (default).
1 indicating Database Mail is available.
The setting takes effect immediately without a server stop and restart.
After enabling Database Mail, you must configure a Database Mail host database to use Database Mail.
Configuring Database Mail using the Database Mail Configuration Wizard enables the Database Mail extended stored procedures in the msdb database. If you use the Database Mail Configuration Wizard, you do not have to use the sp_configure example below.
Setting the Database Mail XPs option to 0 prevents Database Mail from starting. If it is running when the option is set to 0, it continues to run and send mail until it is idle for the time configured in the DatabaseMailExeMinimumLifeTime option.
Examples
The following example enables the Database Mail extended stored procedures.
sp_configure 'show advanced options', 1;
GO
RECONFIGURE;

sp_configure 'Database Mail XPs', 1;
