Problems with Asian Spam

[stefan]

Just comming back to Asian spam, i searched in the database file for entries,
that I have in these mails. I did not found them (because I do not know, what is
really saved). I found that mails with a body like this are not detected
correctly as spam:
--
Content-Type: text/html;
Content-Transfer-Encoding: quoted-printable

  
      =B9=AB=C1=F8-19
  
  


=C0=CE=C5=CD=B3=DD =B1=DD=C0=B6 
=C0=FC=B9=AE=BD=CE=C0=CC=C6=AE=

 
--
This is only part of the whole mail and will be interpreted by the mail program
as nice colored Asian text with correct HTML code. 
I searched for "=B9=AB=C1=F8-19" and "=B9" in the database, but I was not
successful. Any idea what I am doing wrong?

Thank you
Stefan.
