Date: Mon, 30 Sep 2013 11:54:15 -0600 [13:54:15 EDT]The attached document is starts with "Documents_" and then has the first part of the recipient's email address as part of the filename. Or that's the way it is meant to work because in practice it will probably be a different recipient in the same domain. Inside is an executable file with the date encoded into the filename (in this case Documents_09302013.exe).

The executable file is (obviously) malware, and has a VirusTotal detection rate of just 3/48. Automated analysis    shows an attempted connection to the site demandtosupply.com on 184.108.40.206 (ioMart, UK) which is a server spotted in a similar attack a few weeks ago.
Unfortunately, where more than one domain on a server is compromised then it looks like the bad guys have complete control of the server and can do what they like. There are a number of legitimate sites (including one IT security company) on this box (listed below), so exercise caution if deciding to block them.
