Configuration for sending Mail on Job fail

Hi All,

I have a requirement to send a mail, when ever the job fail. I tried with smtp_to() and Mail_to() function but with both i am unable to send mail, I configured the sender and server info in DS server manager. but still not able to send the mail. I need to send mail to the customer gmail. What are else configurations i need to do. can any one please help me.

I followed the Note1573029

but at fourth step i am facing an issue as the user is not authenticated to send anonymous mail.

Thanks
