After changing the password for my UEC account, I can no longer receive emails (IMAP, POP3).
Access to the server may be blocked due to multiple consecutive authentication failures within a short period of time. Please try the following steps.
Temporarily stop all regular email reception check functions on all devices you are using.
Leave it for about 30 minutes to 1 hour
Restart the reception check function one device at a time
After a password has been changed, there are many cases in which authentication failures occur due to periodic reception checks from terminals that store the old password, and access to the authentication server is blocked. After changing your password, please change the password to the new one on all your devices.
If you do not know how to stop the automatic reception check function, try disconnecting your device from the network or deleting all email settings.
The email I thought I sent did not reach the recipient. The email that was supposed to be sent has not arrived.
Please check the following steps:
If you are using a spam mail protection function, please check your “spam mail folder” once again.
If you have configured forwarding settings, please check that the forwarding settings are correct once again.
Please try sending/receiving by temporarily disabling your security software.

Sent or received emails, or both, are garbled.
Depending on the text encoding of your email software, emails may be garbled. If your email is garbled, please check the text encoding settings of your email software. Details such as procedures vary depending on the email software you are using. We apologize for the inconvenience, but please check the manual of the email software you are using.
[SPAM] is added to the title of legitimate emails.
This is added by the spam detection function of the security device. We will adjust the settings so that it will not be added in the future, so please send all email header information (not just the addressee and sender, but also all information such as server sending/receiving history) to support@cc.uec.ac.jp . The method of checking email header information differs depending on the email software you are using. Please check the manual of each email software.Please note that security devices judge spam mail based on various conditions, so [SPAM] may still be added even after adjusting the settings.

For this setting only, please approve the security exception and proceed with the procedure.
A security warning screen like the one below may appear. This confirms the validity of access to the University of Dentsu server that Thunderbird refers to in order to obtain configuration information.
We plan to correct this error, but until it is corrected, please temporarily approve the exception and use it.
