ORF Rejecting Emails due to Blacklisted by Charset Blacklist RSS

Blacklisted by the charset blacklist. Filter comment: "Japanese".

@Rommel J. Jimenez: Most likely you have the Charset Blacklist test enabled (Administration Tool: Configuration / Tests / Tests), Japanese is checked under Configuration / Filtering - On Arrival / Charset Blacklist and the email (or a part of it) is encoded in iso-2022-jp.

ORF searches the email subject and any body parts for character set declarations. If any of the collected charsets match with any of the charsets on the Charset blacklist, the email will be blacklisted.

Character sets are declared in the email header, email part headers and the subject. In Microsoft Outlook, you can view this information under the View | Options menu (see Internet Headers).

In the email header and part headers, the charset declaration typically looks like this:

Content-Type: text/plain; charset=iso-2022-jp

In subjects, the charset is encoded as:

Subject: ?=iso-2022-jp?B?ASDFGH=
