Works great for me (inevitably). The only suggestion I have is to edit 
/usr/lib/MailScanner/MailScanner/Message.pm. Around line 4407 there 
should be a line that says this:
                                            Id => '<' . $internalname . 
'>');
Change that to
                                            'Content-Id:' => '<' . 
$internalname . '>');
Then
    service MailScanner restart

and let me know if this helps at all.
