We stopped updating this site on June 30, 2024. From now on, information on Educational Campus-wide Computing System (ECCS) will be provided at utelecon The Portal Site of Information Systems @ UTokyo.
We plan to introduce DKIM authentication for ECCS Cloud Email by around October 2023.
By validating DKIM authentication, recipients will be better able to detect spoofing and tampering in emails originating from the ECCS Cloud Email address (g.ecc.u-tokyo.ac.jp).
Details will be added as soon as they are finalized.
(Added on 2023-10-05) DKIM authentication is scheduled to be validated on Monday, October 16, 2023.
Please note that the settings may take up to 48 hours to reflect entirely due to DNS and Google's processing.
(Added on 2023-10-16) DKIM authentication was activated on Monday, October 16, 2023, around 15:30.
