Installs and configures Dovecot.


Creates the dovecot system user. Used by the default recipe.


Generates all the configuration files. Used by the default recipe.


Provides an Ohai plugin for reading dovecot install information.


Installs the required packages. Used by the default recipe.


Configures the Dovecot service. Used by the default recipe.

Ohai Plugin

The ohai_plugin recipe installs an Ohai plugin. It will be installed and activated automatically.

It will set the following attributes:

  • node['dovecot']['version']: version of Dovecot.
  • node['dovecot']['build-options']: some Dovecot build options.
    • node['dovecot']['build-options']['mail-storages']
    • node['dovecot']['build-options']['sql-driver-plugins'] or node['dovecot']['build-options']['sql-drivers']
    • node['dovecot']['build-options']['passdb']
    • node['dovecot']['build-options']['userdb']

This is an output example:

"dovecot": {
  "version": "2.0.19",
  "build-options": {
    "ioloop": "epoll",
    "notify": "inotify",
    "ipv6": true,
    "openssl": true,
    "io_block_size": "8192",
    "mail-storages": [
    "sql-driver-plugins": [
    "passdb": [
    "userdb": [

Usage Examples

Including in a Cookbook Recipe

You can simply include it in a recipe:

# from a recipe
include_recipe 'dovecot'

Don't forget to include the dovecot cookbook as a dependency in the metadata.

# metadata.rb

depends 'dovecot'

Including in the Run List

Another alternative is to include the default recipe in your Run List.

  "name": "",
  "run_list": [

Authentication Database Examples

Authentication database attributes, inside passdb or usedb hash values, can contain both arrays or hashes.

Supported auths are the following: checkpassword, deny, ldap, master, passwdfile, sql, system and vpopmail.

node.default['dovecot']['auth']['checkpassword'] = {
  'passdb' => { # hash
    'driver' => 'checkpassword',
    'args' => '/usr/bin/checkpassword',
  'userdb' => {
    'driver' => 'prefetch',
node.default['dovecot']['auth']['system']['passdb'] = [ # array
    # without driver
    'args' => 'dovecot',
    'driver' => 'passwd',
    'args' => '',
    'driver' => 'shadow',
    'args' => '',
    'driver' => 'bsdauth',
    'args' => '',

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 conaint 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 Example

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' => [ '$mail_plugins' ],

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 and managesieve.

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',

  • vagrant
  • berkshelf >= 2.0
  • test-kitchen >= 1.2
  • kitchen-vagrant >= 0.10

Running the tests

$ kitchen test
$ kitchen verify

Running the tests in the cloud


  • kitchen-vagrant >= 0.10
  • kitchen-digitalocean >= 0.5
  • kitchen-ec2 >= 0.8

You can run the tests in the cloud instead of using vagrant. First, you must set the following environment variables:

  • AWS_KEYPAIR_NAME: EC2 SSH public key name.
  • EC2_SSH_KEY_PATH: EC2 SSH private key full path.
  • DIGITAL_OCEAN_SSH_KEY_IDS: DigitalOcean SSH numeric key IDs.
  • DIGITAL_OCEAN_SSH_KEY_PATH: DigitalOcean SSH private key full path.

Then, you must configure test-kitchen to use configuration file:

$ kitchen list


  1. Fork the repository on Github
  2. Create a named feature branch (like add_component_x)
  3. Write you change
  4. Write tests for your change (if applicable)
  5. Run the tests, ensuring they all pass
  6. Submit a Pull Request using Github
