@ionizedgirl@toot.cat @llimllib i am struggling basically with the issue described here, Apple Mail refuses to load images from a particular site (even after I've cleaned the tags to be the simplest <img src="...">) that every other mail client i've tested (local and web, including icloud.com) load fine. it's not a privacy-settings issue, just images from this site (which i'm making a newsletter of as an exercise).

i wonder if the nonstandard header isn't the issue.

@ionizedgirl@toot.cat @llimllib (no, it's not. i can serve images with this "host-header" header set, and Apple Mail will display them. i think it must be some subtlety in some providers' HTTP/2 handling upsetting Apple Mail, sending a near identical response in HTTP/1.1 works fine.)
