[dba-SQLServer]SQL Mail

Hi ALL 

I have setup my SQL Mail in the server. 
When I do xp_sendmail from query analyser, it works and I am getting
mail 
But If I put the same command in Job step, it doesn't work. 
No error message also. 
The job just runs and comes out. 
There is no job history updated 
Can anyone help me on this issue ?

Regards
Fred
