Mailing list configuration

Mailing lists can be configured via the REST API.

>>> mlist = create_list('ant@example.com')
>>> transaction.commit()

Reading a configuration

Changing the full configuration

Not all of the readable attributes can be set through the web interface. The ones that can, can either be set via PUT or PATCH. PUT changes all the writable attributes in one request.

When using PUT, all writable attributes must be included.

Changing a partial configuration

Using PATCH, you can change just one attribute.

>>> dump_json('http://localhost:9001/3.0/lists/'
...           'ant@example.com/config',
...           dict(display_name='My List'),
...           'PATCH')
content-length: 0
date: ...
server: ...
status: 204

These values are changed permanently.

>>> print(mlist.display_name)
My List

Sub-resources

Mailing list configuration variables are actually available as sub-resources on the mailing list. Their values can be retrieved and set through the sub-resource.

Simple resources

You can view the current value of the sub-resource.

>>> dump_json('http://localhost:9001/3.0/lists/ant.example.com'
...           '/config/display_name')
display_name: My List
http_etag: ...

The resource can be changed by PUTting to it. Note that the value still requires a dictionary, and that dictionary must have a single key matching the name of the resource.

>>> dump_json('http://localhost:9001/3.0/lists/ant.example.com'
...           '/config/display_name',
...           dict(display_name='Your List'),
...           'PUT')
content-length: 0
date: ...
server: ...
status: 204

>>> dump_json('http://localhost:9001/3.0/lists/ant.example.com'
...           '/config/display_name')
display_name: Your List
http_etag: ...

PATCH works the same way, with the same effect, so you can choose to use either method.

>>> dump_json('http://localhost:9001/3.0/lists/ant.example.com'
...           '/config/display_name',
...           dict(display_name='Their List'),
...           'PATCH')
content-length: 0
date: ...
server: ...
status: 204
>>> dump_json('http://localhost:9001/3.0/lists/ant.example.com'
...           '/config/display_name')
display_name: Their List
http_etag: ...

Acceptable aliases

These are recipient aliases that can be used in the To: and CC: headers instead of the posting address. They are often used in forwarded emails. By default, a mailing list has no acceptable aliases.

>>> from mailman.interfaces.mailinglist import IAcceptableAliasSet
>>> IAcceptableAliasSet(mlist).clear()
>>> transaction.commit()
>>> dump_json('http://localhost:9001/3.0/lists/'
...           'ant@example.com/config/acceptable_aliases')
acceptable_aliases: []
http_etag: "..."

We can add a few by PUT-ing them on the sub-resource. The keys in the dictionary are ignored.

>>> dump_json('http://localhost:9001/3.0/lists/'
...           'ant@example.com/config/acceptable_aliases',
...           dict(acceptable_aliases=['foo@example.com',
...                                    'bar@example.net']),
...           'PUT')
content-length: 0
date: ...
server: WSGIServer/...
status: 204

Aliases are returned as a list on the aliases key.

>>> response = call_http(
...     'http://localhost:9001/3.0/lists/'
...     'ant@example.com/config/acceptable_aliases')
>>> for alias in response['acceptable_aliases']:
...     print(alias)
bar@example.net
foo@example.com

The mailing list has its aliases set.

>>> from mailman.interfaces.mailinglist import IAcceptableAliasSet
>>> aliases = IAcceptableAliasSet(mlist)
>>> for alias in sorted(aliases.aliases):
...     print(alias)
bar@example.net
foo@example.com
