Well, you are not going to belive, it but after makeing the following minor change:

machine smtp.gmail.com login oub.oub.oub@gmail.com port 587 password  XXXXX
machine imap.gmail.com login oub.oub.oub password XXXX port imaps

After  *restarting emacs*, 

I can now again access my private gmail account, 

Sorry for the noise.

May I suggest to add a section to the authinfo info file, describing the
use of gmail app-passwords.

If you like I can give it a try (I would send you my proposal off list)
and you can decide for yourself.

Sometimes a novice (like me concerning gmail app passwords) might mention
things that seem trivial to the expert.
