How postfix handles non-deliverable messages?
Hi All,
I want to know how postfix handles non-deliverable messages. Is there any setting in postfix which says after how many days we should get the message saying my email was not delivered. Before that, how many times it tries to deliver that message and where are all these settings kept in postfix configuration. Whether it can be changed? whether it needs restart of postfix services? This is bit urgent.
Thanks

I was trying to compare these settings to our Exchange Server settings. On Exchange server, there are two options which says this:
Message expiration
Maximum time since submission (days): 2
Notifications
Notify sender when message is delayed more than (hours): 4
Now, on our linux smtp servers the parameters bounce_queue_lifetime is not defined, so I am considering it as 5days. We will get the NDR receipt after 5 days. But is there any notification parameter in postfix just like Exchange Notification option.
Actually, we want to have standard figures in both exchange and postfix environment.
Thanks
