Security enhancement to @u.tsukuba.ac.jp when used via mail software

ACCC will be introducing a feature for security enhancement which works on email clients (PC or smartphone applications for managing email accounts) managing @u.tsukuba.ac.jp. The same security feature has already been working on Active!Mail. This time the feature will be working on email clients which access and manage @u.tsukuba.ac.jp.

The introduction work will be administered as follows:
Description: Introduction of a security feature which locks the associated user’s access for 10 minutes if access fails five times consecutively
Date: Sunday, December 16, 2018

Even if this feature locks a user’s access via an email client, Active!Mail remains accessible. However, if login to Active!Mail fails five time in a row, the associated user’s Active!mail account gets locked for 10 minutes.

Please note that this feature does not work on @s.tsukuba.ac.jp (Office 365).
