gateway.EECS.Berkeley.EDU was unable to deliver email to one of the EECS SMTP servers that expands forwarding for users and mailing lists due to a temporary problem on that SMTP server. gateway.EECS.Berkeley.EDU should have then tried the other EECS SMTP server that expands forwarding, but it did not.
Normal service resumed Friday January 23, 2009 06:14. No email was lost. Warning messages concerning the delivery delay were sent to EECS and ERSO senders after four hours.
Staff is studying the situation and considering options to make the situation more robust in order to prevent future similar unplanned outages/delays.
