I need to know whether my mail is fail to deliver:
I have set the imap setting for my mail box.
when i use zend to retrieve all mail message, how can i detect the mail is bounce message?
if i use "failure" title to filter, other mail that is not related will also be select as bounce mail?
Also, the bounce mail box must be the sender mail box , it is set by the mail server , no matter i add header in the message, that mean i can not change to another mail box to receive bounce mail?
Thank you.
