Hi Eli,

thanks very much, this helped.

Now I can open Emacs without error message.
-------------------------------------------------------
next problem:

When opening gnus   it can´t open my emails.

Opening nnimap server on posteo...failed: NO (AUTHENTICATIONFAILED)
Authentication failed.

1.
I have got this in my ".authinfo" file:

machine posteo login gottfried@posteo.de password my_password port 993
imaps
machine posteo login gottfried@posteo.de password my_password port 465

or only one sentence:
machine posteo login gottfried@posteo.de port imaps password my_password
but this sentence seems to be wrong. missing the port number.

I don´t know which of the two is better?

Independently of that there is may be an other mistake somewhere.

2.
I tried to put the .authinfo file in my .config/emacs folder
or also in my /home/gfp folder
In both cases it doesn´t work.

Is it better to put the .authinfo file into .config/emacs or into the
home folder /home/gfp ?

thanks for help.
Without help I am lost.
