Dekko renders HTML and TEXT mail with an inline PNG
I'm spammed with SCAM mails which want my money, of course. The mails are in HTML and TEXT and the HTML has an inline image, included in the mail. I've configured in Dekko that I prefer TEXT. Why is the HTML rendered and the image shown? The external content is not presented and blocked. But the image itself could already be malicious.
I suggest you create an issue on Dekko's issue tracker.
