I have an iphone 11 and I also have an imac 2015 running High Sierra, 10.13.6. Since upgrading to High Sierra I can no longer email photos to myself from my Iphone. They go to my email server, but Mail cannot downloadn them. The email arrives in Mail, but there is an icon that says the photo is downloading, but it never does. If I send the photo to someone else, they get it fine. When they email it to me, Mail cannot download it.
This only happens with photos sent from my iphone. Photos that do not originate on my phone can be received in Mail normally.
