There has been an incident with docomo Mail where delivered e-mails have been determined to be spoofed e-mails.

Thank you for using Ichihara City Information Mail.

If you are using docomo's email service "Soku Mail Plus+" （ provided by Visor Corporation ）, you may receive a message
"This email has been sent. domain authentication has not been performed. It may be a spoofed email.
is displayed when opening an incoming mail.

According to Visor, it is still possible to view the contents of the email even when the warning is displayed.
The company is currently investigating ways to improve the situation, but it is expected to take some time.
We will notify you by e-mail when there is progress.

We apologize for any inconvenience caused.
