With respect to the bMail simplification program/project

bMail continues to handle @cs and @eecs bMail aliases
and bConnected lists (Google groups).

IRIS is now handling all other @cs and @eecs email forwarding.
This includes @cs and @eecs mail forwarding for people that don’t
have a bMail account and mailing lists that are not bConnected lists.
Formerly, the CalNet owner of such a redirect could update the
destination via the CalMail “Manage Your Redirects” gui
(graphical user interface); this functionality has been
deprecated/retired. For updates to all @cs and @eecs email
forwarding, please contact the IRIS Helpdesk via help@eecs

It is more robust for @eecs (and @cs) email to
be delivered to a bMail account or a
bConnected list. For helping converting an
email address to a bMail alias or a bConnected list,
please contact the IRIS Helpdesk via help@eecs.

During the February 16, 2017 until the morning of
Monday March 13, 2017 time frame, Google was sending probable
spam to @eecs email forwarding (handled by IRIS).

At 8am Monday March 13, 2017, Google was configured to
no longer attempt to send spam to @eecs email forwarding.
When bMail receives what Google determines is probably
spam destined for @eecs email forwarding, Google sometimes
bounces the mail back to the sender as “Address not found.”
