    I think I found the problem, which was the native iPhone mail app. Once I tried some different mail apps, I found at least 3 apps that were working (like airmail).

    My guess is that iPhone’s default mail app doesn’t accept servers self-signed certificate even if the certificate is trusted on a phone.
