Working on sending MIME attachments via Net::SMTP has got me
scrutinizing my headers.  Here is one I think I need to fix:

X-Spam-Status: No, score=2.9 required=5.0 tests=AWL,BAYES_00,
	DNS_FROM_OPENWHOIS,FH_DATE_PAST_20XX,HELO_LH_LD autolearn=no
version=3.2.5 Received: from localhost.localdomain (demo.opsdc.com
[65.254.219.6]) by support.opsdc.com (8.13.8/8.13.8) with ESMTP id
o58ESdQe022189 for <cfowler at opsdc.com>; Tue, 8 Jun 2010 10:28:40 -0400
Date: Tue, 8 Jun 2010 10:28:39 -0400

X-Spam-Status:

FH_DATE_PAST 20XX

The server's localtime is 10:28:39 EDT

why did my email get points for FH_DATE_PAST?
