It's probably a permissions issue. You need to log into windows with the same account that you created the mail profile in as well as the same account that sqlserver and/or sql server agent are running under. You must also ensure that this account is a member of the local administrator group as well as have the necessary domain rights to run a mail session.

I check. i have already started all services using my
domain user account.
but when i check the sql server agent Error Log
i could see a error as
"[000] Password verification of the 'SQLAgentCmdExec' proxy account failed (reason: A required privilege is not held by the client)"

can this be the problem.
if so how could i fix it
