Mailu command line
==================
Managing domains, users and aliases can be done from CLI using the commands:
* alias
* alias-delete
* domain
* password
* user
* user-import
* user-delete
* config-update
* config-export
* config-import
alias
-----
.. code-block :: bash
docker compose exec admin flask mailu alias foo example.net "mail1@example.com,mail2@example.com"
alias-delete
------------
.. code-block :: bash
docker compose exec admin flask mailu alias-delete foo@example.net
domain
------
.. code-block :: bash
docker compose exec admin flask mailu domain example.net
password
--------
.. code-block :: bash
docker compose exec admin flask mailu password myuser example.net 'password123'
user
----
.. code-block :: bash
docker compose exec admin flask mailu user myuser example.net 'password123'
user-import
-----------
primary difference with simple `user`
.. code-block :: bash
docker compose run --rm admin flask mailu user-import myuser example.net '$6$51ebe0cb9f1dab48effa2a0ad8660cb489b445936b9ffd812a0b8f46bca66dd549fea530ce' 'SHA512-CRYPT'
user-delete
-----------
Although the action is called "user-delete" the user is only deactivated by default.
This is due to the fact mailu does not remove user-data (emails and webmail contacts) when a user is deleted.
Add the flag `-r`
.. code-block :: bash
docker compose exec admin flask mailu user-delete foo@example.net
config-update
-------------
The sole purpose of this command is for importing users/aliases in bulk and synchronizing DB entries with external YAML template:
.. code-block :: bash
cat mail-config.yml | docker compose exec -T admin flask mailu config-update --delete-objects
where mail-config.yml looks like:
.. code-block :: bash
users:
- localpart: foo
domain: example.com
password_hash: klkjhumnzxcjkajahsdqweqqwr
aliases:
- localpart: alias1
domain: example.com
destination: "user1@example.com,user2@example.com"
without `` --delete-object `` option config-update will only add/update new values but will *not* remove any entries missing in provided YAML input.
Users
^^^^^
following are additional parameters that could be defined for users:
* comment
* quota_bytes
* global_admin
* enable_imap
* enable_pop
* forward_enabled
* forward_destination
* reply_enabled
* reply_subject
* reply_body
* displayed_name
* spam_enabled
* spam_mark_as_read
* spam_threshold
Alias
^^^^^
additional fields:
* wildcard
.. _config-export:
config-export
-------------
The purpose of this command is to export the complete configuration in YAML or JSON format.
.. code-block :: bash
$ docker compose exec -T admin flask mailu config-export --help
Usage: flask mailu config-export [OPTIONS] [FILTER]...
Export configuration as YAML or JSON to stdout or file
Options:
-f, --full Include attributes with default value.
-s, --secrets Include secret attributes (dkim-key, passwords).
-d, --dns Include dns records.
-c, --color Force colorized output.
-o, --output-file FILENAME Save configuration to file.
-j, --json Export configuration in json format.
-?, -h, --help Show this message and exit.
Only non-default attributes are exported. If you want to export all attributes use `` --full `` .
If you want to export plain-text secrets (dkim-keys, passwords) you have to add the `` --secrets `` option.
To include dns records (mx, spf, dkim and dmarc) add the `` --dns `` option.
By default all configuration objects are exported (domain, user, alias, relay). You can specify
filters to export only some objects or attributes (try: `` user `` or `` domain.name `` ).
Attributes explicitly specified in filters are automatically exported: there is no need to add `` --secrets `` or `` --full `` .
.. code-block :: bash
$ docker compose exec admin flask mailu config-export --output mail-config.yml
$ docker compose exec -T admin flask mailu config-export domain.dns_mx domain.dns_spf
$ docker compose exec -T admin flask mailu config-export user.email user.spam_threshold
config-import
-------------
This command imports configuration data from an external YAML or JSON source.
.. code-block :: bash
$ docker compose exec -T admin flask mailu config-import --help
Usage: flask mailu config-import [OPTIONS] [FILENAME|-]
Import configuration as YAML or JSON from stdin or file
Options:
-v, --verbose Increase verbosity.
-s, --secrets Show secret attributes in messages.
-q, --quiet Quiet mode - only show errors.
-c, --color Force colorized output.
-u, --update Update mode - merge input with existing config.
-n, --dry-run Perform a trial run with no changes made.
-?, -h, --help Show this message and exit.
To pass stdin correctly you have to use the `-T`
.. code-block :: bash
docker compose exec -T admin flask mailu config-import -nv < mail-config.yml
mail-config.yml contains the configuration and looks like this:
.. code-block :: yaml
domain:
- name: example.com
alternatives:
- alternative.example.com
user:
- email: foo@example.com
password_hash: '$2b$12$...'
hash_scheme: MD5-CRYPT
alias:
- email: alias1@example.com
destination:
- user1@example.com
- user2@example.com
relay:
- name: relay.example.com
comment: test
smtp: mx.example.com
config-import shows the number of created/modified/deleted objects after import.
To suppress all messages except error messages use `` --quiet `` .
By adding the `` --verbose `` switch the import gets more detailed and shows exactly what attributes changed.
In all log messages plain-text secrets (dkim-keys, passwords) are hidden by default. Use `` --secrets `` to log secrets.
If you want to test what would be done when importing without committing any changes, use `` --dry-run `` .
By default config-import replaces the whole configuration. `` --update `` allows to modify the existing configuration instead.
New elements will be added and existing elements will be modified.
It is possible to delete a single element or prune all elements from lists and associative arrays using a special notation:
+-----------------------------+------------------+--------------------------+
| Delete what? | notation | example |
+=============================+==================+==========================+
| specific array object | `` - -key: id `` | `` - -name: example.com `` |
+-----------------------------+------------------+--------------------------+
| specific list item | `` - -id `` | `` - -user1@example.com `` |
+-----------------------------+------------------+--------------------------+
| all remaining array objects | `` - -key: null `` | `` - -email: null `` |
+-----------------------------+------------------+--------------------------+
| all remaining list items | `` - -prune- `` | `` - -prune- `` |
+-----------------------------+------------------+--------------------------+
The `` -key: null `` notation can also be used to reset an attribute to its default.
To reset *spam_threshold* to it's default *80* use `` -spam_threshold: null `` .
A new dkim key can be generated when adding or modifying a domain, by using the special value
`` dkim_key: -generate- `` .
This is a complete YAML template with all additional parameters that can be defined:
.. code-block :: yaml

- name: example.com

- alternative.tld
