Commenting just ssl_min_protocol = TLSv1.2 seems to solve the problem. So I have the default ssl_min_protocol = TLSv1
with means that the device running k9 is not supporting TLS 1.2 yet
TLS 1.2 is enabled by default in Android versions 5.0 and newer. For earlier Android versions, K9 has (or used to have) a setting to "harden" its SSL/TLS settings, which enables TLS 1.2 as far back as 4.3 or something. -- K
The android runs Version 4.0.3 ;) Don't know how to enable TLS 1.2.

Oh well. Android supports TLS 1.2 at all since version 4.1 - so the setting I'd mentioned above won't have helped anyway. https://developer.android.com/reference/javax/net/ssl/SSLSocket -- K
