I failed to disclose that the described problem occurs on iOS 13.0 beta.
After trying again and again, it appears that a bug in iOS 13.0 beta is the likely culprit. I am reading on Reddit that there is some bug in iOS with certificate trust... I am accessing my dovecot mail via iOS 13 beta without issue. (noe on eta 3, but had no issues with beta 2 or 3. Well, no issues with MAIL that is).
I am running current doevcot.
I just opened the mail client on my phone:
imap(kremels@kreme.com)<12940><14ffIdeMDf9JDqGg>: ID sent: name=iPhone Mail, version=17A5522f, os=iOS, os-version=13.0 (17A5522f)
I think the problem manifests itself when using custom CA certificates.
