I'm a happy Fastmail customer, except there's one major annoyance in the web interface: large images, like screenshots, completely break the viewport.

You have to scroll the browser horizontally for 2000 pixels sometimes, looking at fractions of the image at a time (or download each embedded image and open it in a local viewer to contain it to your screen size).

Fastmail support replied essentially "won't fix".
