Spam Karma email encoding

Hi, I’ve installed SK on WP 1.5b and it’s running like a beauty. But when I receive email notification after spam being deleted, the email messages came out in garble.

Here’s a sample in one of yhe mails received:

Content-Type: text/plain; charset=”utf-8″

Mime-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: BASE64

U3BhbSBLYXJtYSBEaWdlc3QgUmVwb3J0OgoKNSBjb21tZW50cyBkaWdlc3RlZCBzaW5jZSBsYXN0

UF9WSUEgaGVhZGVyLgpPU0E6IENvZGUgb3IgdGltZSBub3QgaW4gc3VibWlzc2lvbi4KQXV0aG9y

I assume this has something to do with the character encoding at the WP admin page? Please help! Thanks!
