Certificate Not Trusted on iPhone, fixed

9/8/20: Solution for me on my IMAP email: Settings, Mail accounts (Password & Accounts), choose problem email account: open Account, check “Incoming Mail Server”:

make sure User Name has a . (Period) and not @

i.e. skippy@skippyjar.com SHOULD BE skippy.skippyjar.com

It worked for me.
