Domains
=======
.. # The test framework starts out with an example domain, so let's delete
# that first.
>>> from mailman.interfaces.domain import IDomainManager
>>> from zope.component import getUtility
>>> manager = getUtility(IDomainManager)
>>> manager.remove('example.com')
<Domain example.com...>
Domains are how Mailman interacts with email host names and web host names.
::
>>> from operator import attrgetter
>>> def show_domains(*, with_owners=False):
... if len(manager) == 0:
... print('no domains')
... return
... for domain in sorted(manager, key=attrgetter('mail_host')):
... print(domain)
... owners = sorted(owner.addresses[0].email
... for owner in domain.owners)
... for owner in owners:
... print('- owner:', owner)
>>> show_domains()
no domains
Adding a domain requires some basic information, of which the email host name
is the only required piece. The other parts are inferred from that.
>>> manager.add('example.org')
<Domain example.org>
>>> show_domains()
<Domain example.org>
We can remove domains too.
>>> manager.remove('example.org')
<Domain example.org>
>>> show_domains()
no domains
Sometimes the email host name is different than the base url for hitting the
web interface for the domain.
>>> manager.add('example.com')
<Domain example.com>
>>> show_domains()
<Domain example.com>
Domains can have explicit descriptions, and can be created with one or more
owners.
::
>>> manager.add(
... 'example.net',
... description='The example domain',
... owners=['anne@example.com'])
<Domain example.net, The example domain>
>>> show_domains(with_owners=True)
<Domain example.com>
<Domain example.net, The example domain>
- owner: anne@example.com
Domains can have multiple owners, ideally one of the owners should have a
verified preferred address. However this is not checked right now and the
configuration's default contact address may be used as a fallback.
>>> net_domain = manager['example.net']
>>> net_domain.add_owner('bart@example.org')
>>> show_domains(with_owners=True)
<Domain example.com>
<Domain example.net, The example domain>
- owner: anne@example.com
- owner: bart@example.org
Domains can list all associated mailing lists with the mailing_lists property.
::
>>> def show_lists(domain):
... mlists = list(domain.mailing_lists)
... for mlist in mlists:
... print(mlist)
... if len(mlists) == 0:
... print('no lists')
>>> net_domain = manager['example.net']
>>> com_domain = manager['example.com']
>>> show_lists(net_domain)
no lists
>>> create_list('test@example.net')
<mailing list "test@example.net" at ...>
>>> transaction.commit()
>>> show_lists(net_domain)
<mailing list "test@example.net" at ...>
>>> show_lists(com_domain)
no lists
In the global domain manager, domains are indexed by their email host name.
::
>>> for domain in sorted(manager, key=attrgetter('mail_host')):
... print(domain.mail_host)
example.com
example.net
>>> print(manager['example.net'])
<Domain example.net, The example domain>
As with dictionaries, you can also get the domain. If the domain does not
exist, ``None`` or a default is returned.
::
>>> print(manager.get('example.net'))
<Domain example.net, The example domain>
>>> print(manager.get('doesnotexist.com'))
None
>>> print(manager.get('doesnotexist.com', 'blahdeblah'))
blahdeblah
