Command line list creation

A system administrator can create mailing lists by the command line.

>>> from mailman.testing.documentation import cli
>>> command = cli('mailman.commands.cli_lists.create')

You can prevent creation of a mailing list in an unknown domain.

>>> command('mailman create --no-domain ant@example.xx')
Usage: create [OPTIONS] LISTNAME
Try 'create --help' for help.

Error: Undefined domain: example.xx

By default, Mailman will create the domain if it doesn’t exist.

>>> command('mailman create ant@example.xx')
Created mailing list: ant@example.xx

Now both the domain and the mailing list exist in the database.

>>> from mailman.interfaces.listmanager import IListManager
>>> from zope.component import getUtility
>>> list_manager = getUtility(IListManager)
>>> list_manager.get('ant@example.xx')
<mailing list "ant@example.xx" at ...>

>>> from mailman.interfaces.domain import IDomainManager
>>> getUtility(IDomainManager).get('example.xx')
<Domain example.xx>

The command can also operate quietly.

>>> command('mailman create --quiet bee@example.com')
>>> mlist = list_manager.get('bee@example.com')
>>> mlist
<mailing list "bee@example.com" at ...>

Setting the owner

By default, no list owners are specified.

>>> from mailman.testing.documentation import dump_list
>>> dump_list(mlist.owners.addresses)
*Empty*

But you can specify an owner address on the command line when you create the mailing list.

>>> command('mailman create --owner anne@example.com cat@example.com')
Created mailing list: cat@example.com

>>> mlist = list_manager.get('cat@example.com')
>>> dump_list(repr(address) for address in mlist.owners.addresses)
<Address: anne@example.com [not verified] at ...>

You can even specify more than one address for the owners.

>>> command('mailman create '
...         '--owner anne@example.com '
...         '--owner bart@example.com '
...         '--owner cate@example.com '
...         'dog@example.com')
Created mailing list: dog@example.com

>>> mlist = list_manager.get('dog@example.com')
>>> from operator import attrgetter
>>> dump_list(repr(address) for address in mlist.owners.addresses)
<Address: anne@example.com [not verified] at ...>
<Address: bart@example.com [not verified] at ...>
<Address: cate@example.com [not verified] at ...>

Setting the language

You can set the default language for the new mailing list when you create it. The language must be known to Mailman.

>>> command('mailman create --language xx ewe@example.com')
Usage: create [OPTIONS] LISTNAME
Try 'create --help' for help.

Error: Invalid language code: xx

>>> from mailman.interfaces.languages import ILanguageManager
>>> getUtility(ILanguageManager).add('xx', 'iso-8859-1', 'Freedonian')
<Language [xx] Freedonian>

>>> command('mailman create --language xx ewe@example.com')
Created mailing list: ewe@example.com

>>> mlist = list_manager.get('ewe@example.com')
>>> print(mlist.preferred_language)
<Language [xx] Freedonian>

Notifications

When told to, Mailman will notify the list owners of their new mailing list.

>>> command('mailman create '
...         '--notify '
...         '--owner anne@example.com '
...         '--owner bart@example.com '
...         '--owner cate@example.com '
...         'fly@example.com')
Created mailing list: fly@example.com

The notification message is in the virgin queue.

>>> from mailman.testing.helpers import get_queue_messages
>>> messages = get_queue_messages('virgin')
>>> len(messages)
1

>>> for message in messages:
...     print(message.msg.as_string())
MIME-Version: 1.0
...
Subject: Your new mailing list: fly@example.com
From: noreply@example.com
To: anne@example.com, bart@example.com, cate@example.com
...

The mailing list 'fly@example.com' has just been created for you.
The following is some basic information about your mailing list.

There is an email-based interface for users (not administrators) of
your list; you can get info about using it by sending a message with
just the word 'help' as subject or in the body, to:

    fly-request@example.com

Please address all questions to noreply@example.com.
