Either (1) the document isn't really a document, or (2) there is
another attachment to the message that is being trapped by the Windows
Executable Magic test.

It is very possible that the Windows Magic test is generating a false
positive. The single test that is matching looks pretty short to me...

Verify that the document is actually a document, scan it with an A/V
tool, and manually deliver it.

How frequently is this happening?
