It gets 10/10 the full score.

It's currently showing 5.9/10, but that's because someone sent an empty test message, e.g.:

Message appears to have no textual parts and no Subject: text.

...WAIT, it's also because that's (currently) a URL for a test of email from a different system: It's from asd0710fghjkl@gmail.com and sent via a google server:
Received: from mail-oi1-f173.google.com (mail-oi1-f173.google.com [209.85.167.173])

Not mxroute.com.

Whence the mixup?
