add rules $signed_header_fields to configuration amavis (/etc/amavis/conf.d/50-user)
$signed_header_fields{'to'} = 1;
$signed_header_fields{'from'} = 1;
$signed_header_fields{'received'} = 0;
$signed_header_fields{'subject'} = 1;
$signed_header_fields{'message-id'} = 1;
$signed_header_fields{'content-type'} = 1;
$signed_header_fields{'date'} = 1;
$signed_header_fields{'mime-version'} = 1;Done
