If the message bounces (i.e. permanent error with a 5xx code), it will not be tried again. It will be returned to the envelope sender. All MTAs should behave this way. On the other hand, if there is a temporary error (4xx code, also known as a deferral), qmail will retry periodically for a period of time set by /var/qmail/control/queuelifetime, which defaults to one week. If you need more details, there is a table of retry intervals for the default queuelifetime in "Life with qmail" by Dave Sill. > If qmail give up, how it process the bounced email? delete it from queue > and forward it to Mail-daemon@localhost?

To modify the queue manually, you must stop qmail first. Read about this on www.qmail.org first.
