I setup a new user called sales, and gave it a password. Although it has a home directory, i set login to /sbin/nologin.
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).
Thanks for your help.
