 Monitoring and audits usually come after a failure of some sort. Nobody
 thought they needed to make sure all servers are checked for queued unsent
 messages, because the software will *always* do the "right thing."

 I'm sure email didn't have the 5 day deletion after non-delivery when it
 first started out either. Someone got an email a few months late and
 decided some cleanup needed to happen.

 Now you've got custom software running everywhere and similar alerting and
 purging requirements were not made explicitly on how long to hold onto the
 messages.

 I run a phone company and we do hold messages that cannot be delivered for
 a period of time less than a week, but I get paged when that queue holds
 more than X messages or any one message exceeds Y time since attempted
 send. It's not hard, but I've seen lots of pretty obvious issues like this
 overlooked and virtually every company regardless of size, even Amazon.
