logging in to postfixadmin failed probably because of a dovecot error

[peacecop kalmer:]

I can’t log in to postfixadmin anymore. It says that the username or 
password is incorrect. It can’t be incorrect as I’ve stored them in 
Google and “Chrome”. I have two admin accounts and none of them can’t be 
used for logging in. So I changed the main password with “setup.php” and 
copied that hash into the configuration file. Then, I deleted one of the 
admin accounts directly in the database from the table “admin”. Finally, 
I tried to recreate that deleted admin account using “setup.php”. I get 
the following error message: “can’t encrypt password with dovecotpw, see 
error log for details”.

I had a look into the error log file of postfixadmin and found these 
complaints:

Is the issue connected to the permission problem? If so why is the 
permission denied?

I can't even receive any mails to the address kalmer at test.tennis24.ee 
anymore. If I send out it works fine but no mail arrives.
