I would like to block some emails which contains certain Japanese words, but spamassassin fails to detect such words when the email is HTML encoded, for example:
This is a multi-part message in MIME format.

Example rule in spamassassin:
body JAP_BAD_1 /残念ながら凶報がございます/
score JAP_BAD_1 5.0
However, when I run the test:
spamassassin -D textcat -t spam.test
It doesn't show up the match. What do I have to do?
