dovecot - Jun 2017 - mail storage auto detection failed?

Hi everyone. Nice to meet you.

I?m new to dovecot and i came across a problem it seems.

I setup a new user called sales with useradd, and gave it a password. Although
it has a home directory, i set login to /sbin/nologin.

When logging into the pop server on port 110 (with telnet) i get this in the
logs:

dovecot: pop3-login: Login: user=<sales>, method=PLAIN, rip=127.0.0.1,  
lip=127.0.0.1, mpid=12938, secured, session=<94SotWVRoAB/AAAB>
Jun  7 21:49:24 www dovecot: pop3(sales): Error: user sales: Initialization
failed: Namespace '': Mail storage autodetection failed with
home=/home/sales
Jun  7 21:49:24 www dovecot: pop3(sales): Error: Invalid user settings. Refer to
server log for more information.


Did i have to initialise the mailbox in the homedirectory? What did i forget. I
didn't change anything to the default dovecot.conf, i just installed the
package with yum install dovecot (so latest version). This error also shows up
when logging into port 143. Thanks for your help.

My dovecot -n output if that helps is :
[ec2-user at www log]$ dovecot -n
# 2.2.10: /etc/dovecot/dovecot.conf
# OS: Linux 4.9.20-10.30.amzn1.x86_64 x86_64
mbox_write_locks = fcntl
namespace inbox {
  inbox = yes
  location   prefix }
passdb {
  driver = pam
}
ssl = required
ssl_cert = </etc/pki/dovecot/certs/dovecot.pem
ssl_key = </etc/pki/dovecot/private/dovecot.pem
ssl_protocols = !SSLv2 !SSLv3
userdb {
  driver = passwd
}

Thanks a lot.

You are missing mail_location, the actual value is dependent on your
filesystem structure and used mail driver

Example:

mail_location = maildir:~/Maildir
