Question:

Why are some of the emails do not comply to the Filter Rule?

Answer:

Please acquire the message source of the mail and send it to the support team.

■Please refer to the procedure for acquiring message source as below;

Additionally, similar to such case, we have experienced the following problem;

The declared character code within the relevant outbound-mail was different than the actually described character code. So, the filter service could not analyze it properly and the mail did not fall under the filter rule.

As a reason why such mail is generated, it is probable that the language of the mail text differs from the setup language setting.  

This is just a reference, but it could help you avoid such failure by changing the settings as follows;

• Gmail settings

1. Click on the gear icon on the right top, then, select [settings].
2. Scroll down till the [outbound mail encoding] section appears.
3. Select [use Unicode (UTF-8) encode for outbound mail]

• Outlook Settings

1. In the [File] menus, click on [option] and open [Outlook Option] dialogue box.
2. In the left menus, click on [advanced settings]
3. Turn off the checkbox [auto-select encoding for outbound message] in [character setting option], select [Unicode (UTF-8)] in [preferentially used encoding in outbound message]

Please check the environment settings of the user who created the mail, and please confirm this settings together.
