RESOLVED: Delay in email delivery for some users
Both issues were resolved between 11:00 AM and 1:00 PM on 7/17. While the characteristics were similar, these are two distinct and separate events.
The VUgmail issue occurred during change # 43643, the script used to update the external email address over-wrote the primary SMTP address with the same value for 51% of the undergraduate student population. This resulted in the senders receiving a “Recipient Not Found” response and complete delivery failure. These messages must be re-sent. This issue was resolved at approximately 1:00 PM on 7/17.
The second issue affected fewer than 10 Vmail users and a small number of resource accounts. These accounts had a legacy internal mail route in their primary SMTP address. Mail routing for these users was restored at 11:00 AM, and the legacy addresses were updated. Technicians believe most, if not all, messages were delivered.
