What does bounced mail mean?
Mail sent across the Internet to another user or even sent to another user on the same machine, will deliver the mail whenever possible. If for any reason it can not deliver the e-mail, the mail program returns the mail with an appropriate message noting the reason for the failure, back to the sender. This is commonly called bounced mail. If a machine addressed by the e-mail is known to exist on Internet, but due to the machine being “down” or the route to the machine being “down”, the Free-Net mailer will queue up the mail and attempt for 3 days to contact the appropriate machine and deliver the mail (checking every 2-4 hours to see if the machine is back up yet). At the end of this period of time it will give up and return the bounced mail to the user.
