[Bug-mailfromd] base64 block in header


Hi Sergey,

I got a 'strange' email I think. I got this weird base64 block in or below the headers. If I decode it is a html page with google tracking pixel.

Is there a way to delete this in mailfromd? Or is this just valid/common use? I think if you embed images in the html they are different from this not? Can't really see the raw source of this message.
