I need some help with my Dovecot and Postfix configs - I'm unable to log in on my mail server

[Nils]

Autocinfiguration is fine, my problem is that once everything is 
(auto)configurated (correctly, checked this) that the server doesn't 
accept my login request.
STARTTLS is correct, ports are correct etc. My mail is correct, my 
password is correct (tried with copy paste) and also with name as 
username and name at domain aswell (name was also copy pasted).
