I try to configure to have user authenticate to a local file called users, with their mailboxes in ../../spool/dovecot, not in their home directories. I have this working correctly with pam authentication on different servers(openSuse and macOS). This server has no pam authentication so I need to use a local file, but I can not make any sense of the documentation, can someone please help on which files I need to change and to which values. I tried several options but getting all kind of errors with UID.

Hi,

The args parameter of userdb contains scheme, username format and location of the password file. Please take a look this link https://doc.dovecot.org/configuration_manual/authentication/passwd_file/

For example, mine is: userdb { driver = passwd-file args = username_format=%u /etc/dovecot/imap.passwd }

$ head /etc/dovecot/imap.passwd to@localhost.local :{plain}1:vmail:vmail::::userdb_mail=mdbox:~/Mdbox/%d/%n:INDEX=~/indexes/%d/%n

I am not sure if I understand it correctly, that this configuration is for each user has its mailbox in its home directory. This is not my intention, I have in 10-mail.conf the mailloration configured as: mail_location = maildir:/opt/local/var/spool/dovecot/%u:LAYOUT=fs

Hi,

There is a note in the document: *For a password database it’s enough to have only the user and password fields. For a user database, you need to set also uid, gid and preferably also home (see VirtualUsers). (gecos) and (shell) fields are unused by Dovecot.* You can leave empty what you don't need.
