We have had reports of some undelivered mail sent via mailing lists on lists.eecs.berkeley.edu. Upon investigating, Google / bMail is refusing to accept some email sent from lists.eecs.berkeley.edu, beginning early on April 24th . We believe this is due to some changes made at the campus level intended to improve mail reliability and reduce spam. We are working with the people running this project to try to determine the cause of the problem and arrive at a resolution.
If you believe you have been impacted by this, any reports of definitely missed emails would be helpful to us in assessing the scope of this problem.
In the meantime, we suggest that any important or time critical emails be also sent directly to individuals instead of relying entirely on mailing lists. For important emails that have been sent already, you may wish to follow up with a phone call or email sent directly to their bMail account.
This article will be updated as we learn more.
Update April 29, 4pm: This problems seems to have resolved itself. There was no definitive diagnosis unfortunately. We will continue to monitor delivery rates on select mailing lists.
