A number of messages that were sent on August 6th and 7th via Denison listservs and from various systems (like the Global Access for DU Self-Service system or the Lanier “Scan to Email” function) were delayed and were just released on August 15th.
This occurred because of a prolonged cleanup process related to a hijacked user account being used to send a huge amount of spam that was identified on 8/6/13. While most of the valid messages were identified and released by 8/9/13, another subset were identified and released yesterday 8/15. At this point, the cleanup process is complete and all messages believed to be valid have been released for delivery.
