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: 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',
}

Complete Example

This is a complete recipe example for installing and configuring Dovecot 2 to work with PostfixAdmin MySQL tables, including IMAP service:

node.default['dovecot']['services']['auth']['listeners'] = [
  # auth_socket_path points to this userdb socket by default. It's typically
  # used by dovecot-lda, doveadm, possibly imap process, etc. Its default
  # permissions make it readable only by root, but you may need to relax these
  # permissions. Users that have access to this socket are able to get a list
  # of all usernames and get results of everyone's userdb lookups.

include_recipe 'dovecot'

# Compile sieve scripts

# this should go after installing dovecot, sievec is required
execute 'sievec sieve_global_path' do
  command "sievec '#{node['dovecot']['conf_path']}/sieve/default.sieve'"
  action :nothing
end
directory ::File.dirname("#{node['dovecot']['conf_path']}/sieve/default.sieve") do
  owner 'root'
  group 'root'
  mode '00755'
  recursive true
  not_if do ::File.exists?(::File.dirname("#{node['dovecot']['conf_path']}/sieve/default.sieve")) end
end

template node['dovecot']['plugins']['sieve']['sieve_global_path'] do
  source 'default.sieve.erb'
  owner 'root'
  group 'root'
  mode '00644'
  notifies :run, 'execute[sievec sieve_global_path]'
