Have a look at Attachment_Overlay.pm



# {{{ sub _OverlayAccessible 
sub _OverlayAccessible {
    {
    TransactionId   => { 'read'=>1, 'public'=>1, 'write' => 0 },
    MessageId       => { 'read'=>1, 'write' => 0 },
    Parent          => { 'read'=>1, 'write' => 0 },
    ContentType     => { 'read'=>1, 'write' => 0 },
    Subject         => { 'read'=>1, 'write' => 0 },
    Content         => { 'read'=>1, 'write' => 0 },
    ContentEncoding => { 'read'=>1, 'write' => 0 },
    Headers         => { 'read'=>1, 'write' => 0 },
    Filename        => { 'read'=>1, 'write' => 0 },
    Creator         => { 'read'=>1, 'auto'=>1, },
    Created         => { 'read'=>1, 'auto'=>1, },
  };
}
