Question:

What should I do when the mail content cannot be displayed in the Email Security's Temporary Suspension interface?

Answer:

HDE One filtering service feature analyzes the sent mail structure to perform filtering processing and to display the text in the mail confirmation screen.

When the RFC noncompliant mail-data is sent and the mail structure cannot be analyzed, the text will not be displayed in the temporarily on-hold mail/ approved mail confirmation screen.

(*)The applicable E-mail data-structure/data-transmission-method are imposed by the RFC regulation.

Please be aware that there might be some cases when G Suite cannot properly judge the encoding of attached files if they are in the text format such as .txt or .csv type.

In such a situation, it is probable that the problem be solved by saving the text file in the “UTF-8” format before attaching onto the outgoing mail.

■The sample cases of G Suite misjudgment on the file text encoding

1) When the mail was sent with attached text file saved in “Shift-JIS” character code.

2) When the character code is declared as “US-ASCII” on the mail data despite that the attached file text’s character code is actually “Shift-JIS”, this will cause a discrepancy between the declared code and the actual one.

Content-Type: text/plain; charset=US-ASCII;(※)
name="=?UTF-8?B?XXXXXXXXXXXXXXXXXXXXXXXXXX..."
