The sender appears to be from info[some-random-number]@Resellers.insureandgo.com, but it is just a simple forgery. Attached is a malicious Word document that I have seen five different versions of (VirusTotal results [1] [2] [3] [4] [5]).

The Malwr reports on the samples [1] [2] [3] [4] [5] show download locations as:
