BCC not blind

[Silver]

Hi,
I'm using IMP version 2.2.0.

I have realized that when I send an email using IMP and I put someone in the
bcc: field, it appears in the message headers...

Here follows the message headers :

<-- cut here -->
Received: from webmail.xxx.com ([xxx.xxx.xxx.xxx])
Message-ID: <977502924.3a4382cc8884a@webmail.xxx.com>
Date: Fri, 22 Dec 2000 17:35:24 +0100
To:  <samuel_piau@xxx.com>
From: Samuel Piau <samuel_piau@xxx.com>
Bcc:  <sam@shoubib.org>
Subject: test message
MIME-Version: 1.0
Content-Type: text/plain
Content-Transfer-Encoding: 7bit
User-Agent: IMP/PHP IMAP webmail program 2.2.0
X-Originating-IP: xxx.xxx.xxx.xxx
<-- cut here -->

So is this a known bug of this version ? Any quick fix ?
