Postal does not process delayed bounce, may be email is not received?

I notice that when sending to domain that dont immediately bounce like Office365 domain, Postal does not show status of such message as bounced. Does Postal process email received in return-path? Or is it because Postal is not receiving any emails at all.

In Postal, a bounce is when a message was fully accepted by a recipient email server and later on the recipient email server sends a bounce message, for example an out-of-office.

If Postal cannot deliver the message at all then this is considered a hard or soft fail and handled differently.

Ok so how does Postal handle bounced that was originally accepted by recipient email server but then sends a bounce message later on?
