Drupal + Postfix Integration Under Ubuntu 8.04 (Hardy) - Page 6

Deliver Incoming Mails Through the Dovecot LDA

To make Postfix use Dovecot you need to append one line to /etc/postfix/master.cf:

vim /etc/postfix/master.cf

dovecot   unix  -       n       n       -       -       pipe
  flags=DRhu user=vmail:vmail argv=/usr/lib/dovecot/deliver -d ${recipient}

Reload Postfix:

/etc/init.d/postfix reload

Now make Postfix deliver mails through this service:

postconf -e virtual_transport=dovecot
postconf -e dovecot_destination_recipient_limit=1

Configure Dovecot

Dovecot supports PO3, POP3S, IMAP and IMAPS. To enable all these services modify /etc/dovecot/dovecot.conf to match the following settings:

vim /etc/dovecot/dovecot.conf

protocols = imap imaps pop3 pop3s
mail_location = maildir:/home/vmail/%d/%n/Maildir
auth default {
  mechanisms = plain login
  passdb sql {
    args = /etc/dovecot/dovecot-sql.conf
  }
  userdb static {
    args = uid=5000 gid=5000 home=/home/vmail/%d/%n allow_all_users=yes
  }
  socket listen {
    master {
      path = /var/run/dovecot/auth-master
      mode = 0600
      user = vmail
    }
    client {
      path = /var/spool/postfix/private/auth
      mode = 0600
      user = postfix
      group = postfix
    }
  }
}
protocol lda {
  log_path = /home/vmail/dovecot-deliver.log
  global_script_path = /home/vmail/globalsieverc
  postmaster_address = [email protected]
  auth_socket_path = /var/run/dovecot/auth-master
  mail_plugins = cmusieve
}

Edit /etc/dovecot/dovecot-sql.conf and make sure the following directives are set:

vim /etc/dovecot/dovecot-sql.conf

driver = mysql
connect = host=127.0.0.1 dbname=drupal_example_com user=drupal_example_com password=opensesame
default_pass_scheme = PLAIN-MD5
password_query = SELECT mail AS user, pass AS password FROM users WHERE mail='%u';

Then you must restart Dovecot:

/etc/init.d/dovecot restart

That’s it! Now Drupal and Postfix share the same authentication repository.
