The e-mail in question minus PDF.

Greetings!

I was just sent a PDF invoice which hit HTML_IMAGE_ONLY_08. Upon closer inspection it turned out to be a 1x1 px tracking image from Mandrill. 

Should that hit HTML_IMAGE_ONLY_08?

Thanks,
Reio

It is hitting based on the "images with 400-800 bytes of words" and wouldn't cause a FP.

Yes, it should hit.  Is it causing an issue with the email overall based on the default scores?
Comment 2 Reio Remma 2018-06-12 16:20:44 UTC
My apologies, I now read the quoted rule description again and it finally dawned on me that I had it backwards. The image isn't 400-800 bytes, but actual text content.

Essentially Mandrill should use an actual picture for the tracking. :)

It didn't cause an issue per se, I usually just look closely at mails I know are legit with a score just around 0.
