there's something strange:

  1.0 HK_RANDOM_FROM         From username looks random
  0.5 FREEMAIL_FROM          Sender email is commonly abused enduser mail
                             provider (xxxxxxxxxxxxx[at]

  1.0 MISSING_FROM           Missing From: header
  1.8 MISSING_SUBJECT        Missing Subject: header

so the spam scanner both did and did not see the From: header.

What do you use for mail scanning?
