Hello,
Email messages written in multi-byte languages, including Japanese
language, usually have MIME encoded headers as defined in RFC 2047.
It makes filtering of messages a little bit difficult, so I wrote
a small patch to enable decoding the headers before filtering if
necessary.
With this patch, you can write your filter like:
> if ${mime_decode:$header_Subject:} contains "brah_brah"
> then
> logwrite "psss, it may be a spam..."
> endif
This "mime_decode" operator also does character set conversion (only
conversion from ISO-2022-JP to EUC-JP is supported right now though),
as well as Base64 or Quoted Printable decoding.
To download or for the detail, please visit the webpage:

I named it 'eximime', but better names welcome :)
