If you want to know whether the recepients have opened your mail there are some other techniques which you can implement.

I didnt got your point. If you want to say that google.com sends a mail that the recepients mail box was not there or some error like that, then it is simple to understand. If you consider a scenario that you are sending mail from your google a/c to some yahoo a/c. You have already handed over your mail to google ( as explained in my previous post)
