dovecot - Jul 2020 - I need some help with my Dovecot and Postfix configs - I'm unable to log in on my mail server

Hello,

currently I'm working on my first mailserver but I can't log in to the 
account I made. For now my client (Mozlla Thunderbird) detects the 
server config (STARTTLS, Port, ...) but it is "Unable to log in at 
server. Probbly wrong configuration, username or passsword".

I know that I added username and password correctly so there must 
something else be wrong.

I run Debian 10 x64 on a fresh installation.
Installed are: postfix, postfix-pcre, dovecot-core, dovecot-imapd and 
dovecot-pop3d.
Dovecot is version 2.3.4.1, Postfix is 3.4.10.

Here are my configurations:
Postfix main.cf: https://pastebin.com/S17jWDQd
Postfix master.cf: https://pastebin.com/W0nynZG6
dovecot.conf: https://pastebin.com/tMD90Znn

This is what my server logs (mail.info, mail.warn) tell me:

(I removed any information from older issues that are already solved, 
thats why mail.warn misses a few lines and there is no mail.err, 
mail.err hadn't any newer messages)

Here is my only line from dovecot's userpass file (/maildata/userpass):

nils at
intern.xxx.xxx:{CRYPT}$2y$05$kkxElxFGsLSyTJwbEaPZzO/QA33vGY3oGyHcgEZa9rpklgBTKQw9O

My postfix vhosts file (/maildir/vhosts)

intern.xxx.xxx

My postfix vmaps file (/maildir/vmaps)

nils at intern.xxx.xxx intern.xxx.xxx/nils/

I've also created the hased database with 'postmap /maildata/vmaps'

This is the script I've used to create my user database: 
https://pastebin.com/9uViNqjB

I haven't worked with postfiy or dovecot yet so there are many things I 
don't know. Because of this a lot of my configurations is copied from an 
iRedMail installation. I know that taking these configs may cause some 
problems but I don't know where to change them or what else is wrong or 
missing.

Thank you for any help!

Thunderbird, for some reason, violates the SMTP standard when attempting 
autoconfiguration. It sends multiple commands ("pipelining") without 
postfix having announced that it's OK to do so.

You can either do the configuration manually (when Thunderbird fails, I 
think you can still go to "manual" or "advanced" or whatever
button to
continue with the configuration), or you could, at least temporarily, 
disable postscreen (which is the only complaining -- rightly -- about the 
improper pipelining), and then enable it again once you have configured 
your account.

You can also read:
https://developer.mozilla.org/en-US/docs/Mozilla/Thunderbird/Autoconfiguration

and set-up the necessary XML file at your server so that Thunderbird can 
pickup the settings automatically. I've done this for one server, but 
don't have the details anymore in my head. The link above should explain 
that all though.

Good luck!
Bernardo

This may help with auto configuration if PHP is available...

https://raw.githubusercontent.com/netserva/sh/master/etc/_.well-known_autodiscover.php

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).

Please provide your configurations processed by the tools postconf and 
doveconf.

There is no SMTP AUTH in the log. Provide the logs from a connection 
where your MUA tries to auth.

And fix the dict_nis_init thing. See alias_maps.
