why won't an email load images
On my new iMac (Retina 5K, 27-inch, 2020 MacOS 10.15.7) sometimes emails won't load images. I tried rebuilding the mailbox and that helped for a few days but the problem returned. This seems like a problem on the new iMac because the same email that most recently wouldn't load there loaded fine on my iPhone and on an older iMac. I tried quitting and restarting Mail and restarting the computer to no effect. Other emails opened ok but some seemed lagged.
