What you call negligible is the fact that email being written into the queue from a remote machine will be lost from either disk or controller write-back cache during a crash. I don't know if that's important or not in your case. Maybe the email(s) that will be lost will not be important. How can we tell? How can we back up email while it's being sent from remote machines? Email queues are not bandwidth-bound, unless most of the messages are big files (which is rarely a case for email), they're seek-bound. > If you are trying to create a system where hardware (or software) > can never lose any of your data, you are Don Quixote and they are > windmills.
