Always Load Images from trusted senders
There should be an option to 'always allow' remote images to load from a particular sender when reading through a message. Perhaps add to the action list.
Even better would be the further option to specify the full email vs the domain i.e. Always allow remote images from <anyone>@dropbox.com
Further thought: Any sender for whom images were loaded manually will thereafter have their images loaded automatically.
Since this is in Desktop app,it would be nice to sync with mobile as well as give the mobile version ability to always trust and load images by sender as well.
Definitely this, synced between macOS and iOS would be even better
