If I send a mail to someone, and put wrong email address. Then a notification mail comes back saying that email id does not exist. If we want to do this process automatically by a java code using javamail api. Then how to check if the received mail is a notification for failed sent mail or not.
I have tried to do this first with gmail. And in gmail, there is a header "x-failed-receipient" which will be not null if the mail is a notification for failed sent mail.
Now I am trying to do this with IBM domino. I want to know if this "x-failed-receipient" header thing is same for all, or is this unique to gmail and IBM Domino will have something unique for it.
