Fri Oct 5 11:45:19 PDT 2001 — When we upgraded our mail server software on bolt (shell) we introduced a bug that caused a small percentage of mail sent from bolt to get stuck in the queue.
We have replaced the mail server software with a new version and processed the old messages. Most were delivered, those that were undeliverable were returned to the sender.
In order to avoid this in the future we are implementing a warning system that will notify our OPS team in the event of excessively old messages or an excessive number of un-delivered messages in the queue.
We apologize for the inconvenience. -Russ
