Cannot find sp_send_cdosysmail

Hello, everyone:

I want to send email by sp_send_cdosysmail, but I got error,

Server: Msg 2812, Level 16, State 62, Line 3
Could not find stored procedure 'sp_send_cdosysmail'.

Even though I run the query under master database. Is it not available in SQL Server 2000?

This is my query:

declare @.Body varchar(4000)
select @.Body = 'This is a Test Message'
exec sp_send_cdosysmail 'someone@.example.com','someone2@.example.com','Test of CDOSYS',@.Body

Any help will be appreciated.

Thanks
