How to make dovecot and postfix use the same mail directory

  • 772

I'm trying to configure postfix and dovecot to connect to the same LDAP, and I kind of succeeded. But now, I have some discrepencies.

The reproduction is as:

  • I connect to dovecot in IMAP with thunderbird
  • I create an email from myself to send to myself
  • I use the postfix from the same server with the same user
  • I send the email

The results are:

  • The sent email is put in the Sent folder.
  • But I get no email in my inbox.

Checking on the server:

  • The sent email is in the /var/mail/<username>/.Sent/cur/ directory
  • The received email is in the /var/mail/<domain>/<username>/new/ directory

I thought I configured the maildir directory both the same way (as in /var/mail/%d/%n), but there must be a problem.

My configuration (external, sorry, couldn't make it in the question. And after 30h (still counting) on those damn configuration files, I'm not really sure which part might impact what…)

  1. Do not deliver messages by postfix. Pass them to the dovecot's deliver instead.

    See https://wiki.dovecot.org/LDA/Postfix for further information.

  2. Keep home_mailbox = in the main.cf empty, and

    smtpd_sasl_type = dovecot

    smtpd_sasl_path = private/auth

    and in dovecot conf

    mail_home = /var/mail/%d/%n

    mail_location = maildir:~

    Also in dovecot conf you need to add or change this:

    service auth {

    unix_listener /var/spool/postfix/private/auth { 
        mode = 0666
        #Change to the user and group of your postfix
        user = postfix  
        group = postfix
    }

    unix_listener auth-userdb {
        mode = 0666
        #Change to the user and group of your postfix
        user = postfix
        group = postfix
    }
    #dovecot user
    user = dovecot

}


service auth-worker {
  # Auth worker process is run as root by default, so that it can access
  # /etc/shadow. If this isn't necessary, the user should be changed to
  # $default_internal_user.
  user = root
}
