As a retired home user I only need access to email from my desktop PC.
So I have used Evolution as mail client interacting with Gmail's server for many years. Receiving email is with Password and sending email is set to Plain; because Evolution in Ubuntu 18.04 does not support the Google security setup OAuth2.
I have read Ubuntu Community Wiki for a couple of hours and checked similar Ask Ubuntu questions.
Is my email secure enough? As an end user age 80 I am not skilled with terminal commands.
Thanks for helping.
