The issue has been resolved and mail is now being delivered. Thank you for your patience.
SSC is currently experiencing deferred email deliveries from our Barracuda Spam Filter appliance. Emails received from external users (ie, not @ucla.edu domains) are currently caught in a queue causing delays to local delivery. We are working to have these emails delivered, users should start receiving these emails to their mailbox within approximately 30 minutes. We apologize for any inconvenience.
Please email firstname.lastname@example.org if you have further questions or issues.
