How to block customized Chinese characters in mail filtering.

[Anton0926]

Hi All,

We want to block Email which subject includes some of Chinese characters.

We can do it by Email filtering ban word function in 4.3 version ,

but now this feature is removed from GUI,it seems only support by CLI after 5.2 version.

Have any way to display ban word option on GUI in firmware 5.2.10 ?

Or Fortigate provides an alternative solution supporting similar function ?

Thanks.
