    Dear people,

    I hope you can give me a hand on this. I am trying to learn about linux. I want to setup a simple solution with postfix and dovecot, eg using text files for users and passwords. I want to do this with virtual users and virtual domains. For now i am on setting up a mail server. I have postfix running and i am able to send emails. My next step is dovecot. I thought i had it all but when trying to login it fails to authenticate.

    in the message log i have this entry.

    dovecot: Oct 26 19:22:45 Info: auth(default): passwd-file([email protected], no passwd file: username_format=user /var/mail/vhosts/

    I have a hard time to understand the relationship between userdb, passdb and shadow if someone could direct me to an article or maybe recommend a book i would be greatful

    Thanks in advance

    If you're using system users, Dovecot should look up the passwords in /etc/shadow.

    This is my dovecot.conf file

    log_path: /var/log/dovecot.log
    info_log_path: /var/log/dovecot-info.log
    ssl_disable: yes
    verbose_ssl: yes
    login_dir: /var/run/dovecot/login
    login_executable(default): /usr/libexec/dovecot/imap-login
    login_executable(imap): /usr/libexec/dovecot/imap-login
    login_executable(pop3): /usr/libexec/dovecot/pop3-login
    mail_location: maildir: /var/mail/vhosts/%d/%n
    mail_debug: yes
    mail_executable(default): /usr/libexec/dovecot/imap
    mail_executable(imap): /usr/libexec/dovecot/imap
    mail_executable(pop3): /usr/libexec/dovecot/pop3
    mail_plugin_dir(default): /usr/lib64/dovecot/imap
    mail_plugin_dir(imap): /usr/lib64/dovecot/imap
    mail_plugin_dir(pop3): /usr/lib64/dovecot/pop3
    auth default:
    mechanisms: plain login CRAM-MD5
    verbose: yes
    debug: yes
    debug_passwords: yes
    driver: passwd-file
    args: username_format=%n /var/mail/vhosts/%d/shadow
    driver: passwd-file
    args: username_format=%n /var/mail/vhosts/%d/passwd
    driver: passwd
    type: listen
    path: /var/spool/postfix/private/auth
    mode: 432

    I am trying to setup virtual users and domains.

    What is the difference between these two settings

    passdb passwd-file {

    userdb passwd-file {

    Thanks in advance
