      'args' => 'dovecot'
      'driver' => 'passwd',
      'args' => ''
      'driver' => 'shadow',
      'args' => ''
      'driver' => 'bsdauth',

Dictionary Quota SQL Example

node.default['dovecot']['conf']['dict_sql']['maps'] =
      'pattern' => 'priv/quota/storage',
      'table' => 'quota',
      'username_field' => 'username',
      'value_field' => 'bytes'
      'pattern' => 'priv/quota/messages',
      'table' => 'quota',
      'username_field' => 'username',
      'value_field' => 'messages'
      'pattern' => 'shared/expire/$user/$mailbox',
      'table' => 'expires',
      'value_field' => 'expire_stamp',
      'fields' => {
        'username' => '$user',
        'mailbox' => '$mailbox'

Namespaces Example

The ['namespaces'] attribute is an array, which could contain both array or hash values.

node.default['dovecot']['namespaces'] = [
    'separator' => '/',
    'prefix' => '"#mbox/"',
    'location' => 'mbox:~/mail:INBOX=/var/mail/%u',
    'inbox' => true,
    'hidden' => true,
    'list' => false
  }, {
    'separator' => '/',
    'prefix' => '',
    'location' => 'maildir:~/Maildir'
  }, { # this requires Dovecot >= 2.1
    'name' => 'inbox',
    'separator' => '/',
    'prefix' => '',
    'inbox' => true,
    'mailboxes' => {
      'Drafts' => {
        'special_use' => '\Drafts'
      'Junk' => {
        'special_use' => '\Junk'
      'Trash' => {
        'special_use' => '\Trash'
      'Sent' => {
        'special_use' => '\Sent'
      'Sent Messages' => {
        'special_use' => '\Sent'
      'virtual/All' => {
        'special_use' => '\All'
      'virtual/Flagged' => {
        'special_use' => '\All'

Plugins Examples

Plugin attribute values should be of type hash.

Supported plugins are the following: mail_log, acl and quota.

Mail Log Plugin Example

node.default['dovecot']['plugins']['mail_log'] = {
  'mail_log_events' =>
    'delete undelete expunge copy mailbox_delete mailbox_rename',
  'mail_log_fields' => 'uid box msgid size'

Sieve Plugin Example

node.default['dovecot']['plugins']['sieve'] = {
  'sieve' => '~/.dovecot.sieve',
  'sieve_dir' => '~/sieve'

Protocols Examples

Protocol attribute values should be of type hash.

Supported protocols are the following: lda, imap, lmtp, sieve and pop3.

node.default['dovecot']['protocols']['lda'] = {
  'mail_plugins' => %w($mail_plugins)

To enable the IMAP protocol without additional settings:

node.default['dovecot']['protocols']['imap'] = {}

Service Examples

The ['services'] attribute is a hash. Each service attribute should be a hash. But the ['listeners'] subkey could contain both a hash and an array.

Inside this listeners key, you should name each listener with the format PROTOCOL:NAME. Allowed protocols are fifo, unix and inet.

Supported services are the following: anvil, director, imap-login, pop3-login, lmtp, imap, pop3, auth, auth-worker, dict, tcpwrap, managesieve-login, managesieve, aggregator, replicator, config.

Director Service Example

node.default['dovecot']['services']['director']['listeners'] = [
  { 'unix:login/director' => { 'mode' => '0666' } },
  { 'fifo:login/proxy-notify' => { 'mode' => '0666' } },
  { 'unix:director-userdb' => { 'mode' => '0666' } },
  { 'inet' => { 'port' => '5432' } }

Imap-login Service Example

node.default['dovecot']['services']['imap-login'] = {
  'listeners' => [
    { 'inet:imap' => { 'port' => 143 } },
    { 'inet:imaps' => { 'port' => 993, 'ssl' => true } }
  'service_count' => 1,
  'process_min_avail' => 0,
  'vsz_limit' => '64M'

Doveadm Service Example

default['dovecot']['services']['doveadm'] = {
  'listeners' => [
    { 'inet:doveadm-server' => { 'port' => 3333 }

Quota-status Service Example

default['dovecot']['services']['quota-status'] = {
  'executable' => 'quota-status -p postfix',
  'listeners' => [
    { 'inet:imap' => { 'port' => 4444 } }

Quota-warning Service Example

default['dovecot']['services']['quota-warning'] = {
  'user' => 'dovecot',
  'executable' => 'script /usr/local/bin/',
  'listeners' => [
    { 'unix:quota-warning' => { 'user' => 'postfix' } }

LDAP Example

This is a recipe example to integrate Dovecot with OpenLDAP. The following cookbooks are used:

# Function to generate the passwords in LDAP format
def generate_ldap_password(password, salt = '12345')
  require 'digest'
  require 'base64'
  digest = Digest::SHA1.digest(password + salt)
  '{SSHA}' + Base64.encode64(digest + salt).chomp
recipe = self

# Create LDAP credentials
ldap_password = 'secretsauce'
ldap_credentials = {
  'bind_dn' => "cn=#{node['openldap']['cn']},#{node['openldap']['basedn']}",
  'password' => ldap_password

# Configure OpenLDAP server
node.default['openldap']['tls_enabled'] = false
node.default['openldap']['rootpw'] = generate_ldap_password(ldap_password)
node.default['openldap']['loglevel'] = 'any'

include_recipe 'openldap::server'

email_account = {
  cn: 'Ole Wobble Olson',
  sn: 'Olson',
  uid: 'wobble',
  uidNumber: '1002', # should be an string for ldap_entry
  gidNumber: '100',
  homeDirectory: '/home/wobble',
  userPassword: recipe.generate_ldap_password('w0bbl3_p4ss')

ldap_entry "uid=wobble,ou=accounts,#{node['openldap']['basedn']}" do
  attributes email_account.merge(objectClass: %w(top person posixAccount))
  credentials ldap_credentials

# Create home directory for the email account
directory email_account[:homeDirectory] do
  owner email_account[:uidNumber].to_i # should be an integer for directory
  group email_account[:gidNumber].to_i

# Dovecot IMAP configuration
node.default['dovecot']['conf']['mail_location'] = 'maildir:~/Maildir'
node.default['dovecot']['protocols']['imap'] = {}
node.default['dovecot']['services']['imap-login'] =
    'listeners' =>
        { 'inet:imap' => { 'port' => 143 } },
        { 'inet:imaps' => { 'port' => 993, 'ssl' => true } }
    'service_count' => 1,
    'process_min_avail' => 0,
    'vsz_limit' => '64M'

# Dovecot LDAP configuration
node.default['dovecot']['conf']['ldap']['auth_bind'] = true
node.default['dovecot']['conf']['ldap']['hosts'] = %w(localhost)
node.default['dovecot']['conf']['ldap']['dn'] = ldap_credentials['bind_dn']
node.default['dovecot']['conf']['ldap']['dnpass'] = ldap_credentials['password']
node.default['dovecot']['conf']['ldap']['base'] = node['openldap']['basedn']
