Forwarding email loads images even with "automatically load images in viewed messages" disabled


Forwarding email loads the images in that email, even with “automatically load images in viewed messages” disabled. As long as the user doesn’t click “show images”, the images simply mustn’t be loaded.

To Reproduce…

Steps to reproduce the behaviour:

  1. Open an html email with images
  2. Click on forward
  3. Discover the images have now all been loaded in the quoted forwarded email, and because of that in the original email too

Expected Behaviour

Remote images are never loaded without explicit user consent.




  • OS and Version: Fedora 35
    • Installation Method: flatpak
  • Mailspring Version: 1.10.3-a476c230

Additional Context

For anyone wondering, remote images are all too often used to track users and are privacy invading.
