Sending email from process chain not working

Hello experts,

I have created a process chain and when the step fails i have created a message to send a email.But i donot receive the email when the step fails.Anythoughts why is it so.I have used the option create mesage by rightcliking on the process step.

I know i can call OS command and send a email using a ABAP program but i donot want to use it.

Thanks and Regards,

Rao
