node['postfix-dovecot']['hostname'] = 'mail.foobar.com'

include_recipe 'postfix-dovecot::default'

postfixadmin_admin 'admin@admindomain.com' do
  password 'sup3r-s3cr3t-p4ss'
  action :create
end

postfixadmin_domain 'foobar.com' do
  login_username 'admin@admindomain.com'
  login_password 'sup3r-s3cr3t-p4ss'
end

postfixadmin_mailbox 'bob@foobar.com' do
  password 'alice'
  login_username 'admin@admindomain.com'
  login_password 'sup3r-s3cr3t-p4ss'
end

postfixadmin_alias 'billing@foobar.com' do
  goto 'bob@foobar.com'
  login_username 'admin@admindomain.com'
  login_password 'sup3r-s3cr3t-p4ss'
end

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

# metadata.rb
[...]

depends 'postfix-dovecot'

Including in the Run List

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

{
  "name": "mail.onddo.com",
  [...]
  "run_list": [
    [...]
    "recipe[postfix-dovecot]"
  ]
}

Testing

Requirements

• vagrant
• berkshelf >= 1.4.0
• test-kitchen >= 1.0.0.alpha
• kitchen-vagrant >= 0.10.0

Running the tests

$ kitchen test
$ kitchen verify
[...]

Running the tests in the cloud

Requirements:

• 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_ACCESS_KEY_ID
• AWS_SECRET_ACCESS_KEY
• AWS_KEYPAIR_NAME: EC2 SSH public key name. This is the name used in Amazon EC2 Console's Key Pars section.
• EC2_SSH_KEY_PATH: EC2 SSH private key local full path. Only when you are not using an SSH Agent.
• DIGITAL_OCEAN_CLIENT_ID
• DIGITAL_OCEAN_API_KEY
• DIGITAL_OCEAN_SSH_KEY_IDS: DigitalOcean SSH numeric key IDs.
• DIGITAL_OCEAN_SSH_KEY_PATH: DigitalOcean SSH private key local full path. Only when you are not using an SSH Agent.

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

$ export KITCHEN_LOCAL_YAML=".kitchen.cloud.yml"
$ kitchen list
[...]

Amazon SES Tests

You need to set the following environment variables:

• AMAZON_SES_EMAIL_FROM: SES valid from address, only used in tests
• AMAZON_SES_SMTP_USERNAME: See Obtaining Your Amazon SES SMTP Credentials documentation.
• AMAZON_SES_SMTP_PASSWORD

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

$ export AMAZON_SES_EMAIL_FROM="no-reply@sesdomain.com"
$ export AMAZON_SES_SMTP_USERNAME="..."
$ export AMAZON_SES_SMTP_PASSWORD="..."
$ export KITCHEN_LOCAL_YAML=".kitchen.ses.yml"
$ kitchen list
[...]
