More Bad Characteristics

System Spam Keywords
This is the filename for the file that contains MailBell's primary list of bad/suspicious words. You can remove predefined words here. If you want to add your own words, please use the Bad Words or Suspicous Words dialog instead, unless you want to achieve very specific results (the System Keywords file is a bit more flexible than the dialogs).
However, the list may be overwritten (after a confirmation window) with an update of MailBell.

Far Eastern Spam
If you receive spam from eastern countries you can here add the character sets from the mail's MIME header which indicate such senders. It is also possible to enable automatic detection of such charsets (which usually appear as illegible characters in the mail body).
