Wrong encoding on russian digest

[kost BebiX]

Hi! I'm receiving mail from trans-ru as a digest and I see something like this:

>>>

Message: 1
Date: Wed, 05 May 2010 08:23:58 +0400
From: "kruvalig at gmail.com" <kruvalig at gmail.com>
Subject: [Fedora-trans-ru] ?????????????? ??? Fedora
To: fedora-trans-ru at redhat.com
Message-ID: <op.vb7s58xka07ebn at kruvaligcomp>
Content-Type: text/plain; charset=koi8-r; format=flowed; delsp=yes

?????????????? ??? ???????? ????????? ? Fedora ????? ?? 
http://stg.fedoraproject.org/ru/index.

<<<

So, letter is in utf-8, but it shows each message was send in koi8-r, but I don't see each message as a message, so all I get is a lot of ?'s. Please fix it just to use utf-8 everywhere. Thank you.
