Difficulties to use Kontact via WIFI from "Flixbus" and similar servers

[Daniel Vrátil]

Hi,

this is an issue specific to Gmail. When Google refuses your login via IMAP, 
then indeed your only chance is to go through web browser, where you probably 
need to type in your OTP code in addition to regular password and confirm it's 
really you.

I wrote a code some time ago that adds support for Google native 
authentication for IMAP, i.e. when trying to log into Gmail, you will get a 
small window popup with the Google login page where you log in, type in your 
OTP code, possibly confirm that its still you just logging in from a new 
location, and it will use the OAuth2 login mechanism. I still have to look 
into how to integrate this into our IMAP code to make it work alongside the 
other authentication methods for non-Gmail servers. So there is some hope, but 
not before 17.04 release in April :)
