Read receipt status with bulk emails

Hi Guys,

I am sending bulk email in my ror app with Gmail SMTP connection using
Action Mailer.

I want to get it's read receipt or email bounce status.

Is there any way to get email sent status? Is it possible with ROR
application

or we have to use any third party tool?

I am using rails2.3.5 on ruby 1.8.7

Thanks
