{#-

  This is the mysql command template for updating all existing users, domains and alias config.
  The following yml is an example confiuration...
############
---
  mailserver__domains:
    - fqdn: example.com

  mailserver__accounts:
    - username: 'alice'
      domain: 'example.com'
      password_hash:  # generate with $(doveadm pw -s SHA512-CRYPT)
        # or $ python -c 'import crypt,getpass; print(crypt.crypt(getpass.getpass(), crypt.mksalt(crypt.METHOD_SHA512)))'
      quota: '0'
      enabled: true
      sendonly: false

  mailserver__alias:
    - src_username: 'bob' # null for catchall
      src_domain: 'example.com'
      dest_username: 'alice'
      dest_domain: 'example.com'
      enabled: true

###############

  OK, first we select the wanted database!

-#}

use vmail;

{#

  Next we will define all existing domains.
  We use INSERT IGNORE to insert the domains and ignore duplicates.

  To delete a domain you have to do it manually using mysql commands or sth. like that!

-#}

INSERT IGNORE INTO domains
  (domain)
values
{% for domain in mailserver__domains %}
  ('{{ domain["fqdn"] }}')
  {%- if loop.last -%}
    ;
  {%- else -%}
    ,
  {%- endif %}

{% endfor %}

{#-

  Now we will define the users and passwords.
  We will use REPLACE to replace updated entrys or add new one.

#}

REPLACE into accounts
  (username, domain, password, quota, enabled, sendonly)
values
{% for account in mailserver__accounts %}
  ('{{ account["username"] }}', '{{ account["domain"] }}', '{{ account["password_hash"] }}', {{ account["quota"]|default(0) | int }}, {{ account["enabled"] | bool | ternary('true', 'false') }} , {{ account["sendonly"] | bool | ternary('true', 'false' )}})
  {%- if loop.last -%}
    ;
  {%- else -%}
    ,
  {%- endif %}

{% endfor %}

{#

  Last we will define some aliases and catchall...

#}

REPLACE into aliases
  (source_username, source_domain, destination_username, destination_domain, enabled)
values
{% for alias in mailserver__alias %}
  (
    {%- if alias["src_username"] == 'null' -%}
      null
    {%- else -%}
      '{{ alias["src_username"] }}'
    {%- endif -%}
      , '{{ alias["src_domain"] }}', '{{ alias["dest_username"] }}', '{{ alias["dest_domain"] }}', {{ alias["enabled"] | bool | ternary('true', 'false') }})
  {%- if loop.last -%}
    ;
  {%- else -%}
    ,
  {%- endif %}

{% endfor %}
