Could you inspect the URLs of the broken images?

There are no URLs. The images are embedded into that mail. Here is a mail snippet of an embedded image:

<div class=3D"p-l-16" style=3D"padding-left: 16px;"><img src=3D"cid:sfp185"=
 alt=3D"" style=3D"border: none;display: block;width: 76px;">
</div>

Look at your screenshot. The browser tries to render images that don't load. Inspect the image tag.

src="cid:sfp185"

bingo.

Even if the images are inline, they are loaded from a URL to be rendered in the browser.

AVM emails are still broken with <img src="cid:myfritz-logo-mail" alt="" style="border: medium; display: block; background-color: transparent; height: 65px; width: 85px; margin-top: 3px; margin-left: 30px; max-width: 100%;">
