Bounce questions

[Ian Layton]

Thank you for all the comments I received about my previous question.

I am now needing to make a program that will analyses bounced messages from
Qmail and be able to distinguish between hard (permanent bounces) and soft
(temporary) bounces. Is there any standard out there on how to recognize the
difference. Also, I would like this program to execute upon delivery of a
bounce message. I believe it's possible but I'm not sure how.

Thank you

Ian
