The CalMail SMTP server will be retired on June 30, 2017 as part of the Email Simplification Program. Campus applications, systems, and devices that are currently using the CalMail server should be reconfigured in advance of this date. The bConnected team has contacted all known departments and individuals impacted by the change, but certain devices (e.g. multifunction devices/scanners) are not easily identifiable and may experience a service interruption if not updated.
