Trying to figure out which step is causing me not to be able tologin. I am using a password file,

We will assume that the pw I created using 'doveadm pw -s SHA512-CRYPT' matches the password I will be using to login below. I crank the debugging mode,
auth_debug_passwords = yes auth_debug = yes
And then try to login
[root@mail ~]# nc -t localhost 143

which from what I gathered from /var/log/dovecot means it found matching username but did not match password:

Per [1] I decided to see what the response (base64-reply) I am submitting to dovecot looks like:
echo 'base64-reply' | base64 -d raub@example.compassword
Which has the right username and password but follows the userpassword format, not useruserpassword as I was led to believe by [1]. Is that to be expected? If it is then the issue is further down the line.
You misunderstood your logs.
Are you sure you have raub@example.com present in /etc/dovecot/passwd? Just having 'raub' there will not work.
