Hvordan sender man en email fra en sql server?

Jeg har prøvet med:

USE master
EXEC xp_startmail
EXEC xp_sendmail 'test@test.com', 'The master database is full.'
EXEC xp_stopmail

Men den fejler med denne besked:
ODBC: Msg 0, Level 16, State 1
Cannot load the DLL sqlmap70.dll, or one of the DLLs it references. Reason: 126(The specified module could not be found.).

Hvad er der galt?
