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.

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,

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

In this file I have following entries and I don’t know what to enter for userdb

passdb {
  driver = passwd-file
  args = /opt/local/etc/dovecot/users
}

userdb {
  driver = passwd-file
  #args = username_format=%u /opt/local/etc/dovecot/users

  # Default fields that can be overridden by passwd-file
  #default_fields = quota_rule=*:storage=1G

  # Override fields from passwd-file
  #override_fields = home=/home/virtual/%u
}

In the users file I have 2 users defined as follow:
user1:{SSHA512}<encrypted password>::::::
user2:{SSHA512}<encrypted password::::::

Dovecot gives following error message on startup:

I don’t know what arguments I have to enter for userdb
