Mailing list configuration
Mailing lists can be configured via the REST API.
>>> from mailman.app.lifecycle import create_list
>>> mlist = create_list('ant@example.com')
>>> from mailman.config import config
>>> transaction = config.db
>>> transaction.commit()
Reading a configuration
All readable attributes for a list are available on a sub-resource.

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')
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')
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')
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 can also be strings beginning
with ^
which are interpreted as regular expressions matched against
addresses in To:
and CC:
headers. 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')
date: ...
server: ...
status: 204
You can get all the mailing list’s acceptable aliases through the REST API.
>>> from mailman.testing.documentation import call_http
>>> 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
The aliases can be removed by using DELETE
.
>>> response = call_http(
... 'http://localhost:9001/3.0/lists/'
... 'ant@example.com/config/acceptable_aliases',
... method='DELETE')
date: ...
server: ...
status: 204
Now the mailing list has no aliases.
>>> aliases = IAcceptableAliasSet(mlist)
>>> print(len(list(aliases.aliases)))
0
Header matches
Mailman can do pattern based header matching during its normal rule
processing. Each mailing list can also be configured with a set of header
matching regular expression rules. These can be used to impose list-specific
header filtering with the same semantics as the global [antispam]
section,
or to have a different action.
The list of header matches for a mailing list are returned on the
header-matches
child of this list.
>>> dump_json('http://localhost:9001/3.0/lists/ant.example.com'
... '/header-matches')
http_etag: "..."
start: 0
total_size: 0
New header matches can be created by POSTing to the resource.
>>> dump_json('http://localhost:9001/3.0/lists/ant.example.com'
... '/header-matches', {
... 'header': 'X-Spam-Flag',
... 'pattern': '^Yes',
... })
content-length: 0
...
location: .../3.0/lists/ant.example.com/header-matches/0
...
status: 201
>>> dump_json('http://localhost:9001/3.0/lists/ant.example.com'
... '/header-matches/0')
header: x-spam-flag
http_etag: "..."
pattern: ^Yes
position: 0
self_link: http://localhost:9001/3.0/lists/ant.example.com/header-matches/0
To follow the global antispam action, the header match rule must not specify
an action
key, which names the chain to jump to if the rule matches. If
the default antispam action is changed in the configuration file and Mailman
is restarted, those rules will get the new jump action. If a specific action
is desired, the action
key must name a valid chain to jump to.
>>> dump_json('http://localhost:9001/3.0/lists/ant.example.com'
... '/header-matches', {
... 'header': 'X-Spam-Status',
... 'pattern': '^Yes',
... 'action': 'discard',
... })
content-length: 0
...

action: discard
header: x-spam-status
http_etag: "..."
pattern: ^Yes
position: 1
self_link: http://localhost:9001/3.0/lists/ant.example.com/header-matches/1
The resource can be changed by PATCHing it. The position
key can be used
to change the priority of the header match in the list. If it is not supplied,
the priority is not changed.
>>> dump_json('http://localhost:9001/3.0/lists/ant.example.com'
... '/header-matches/1',
... dict(pattern='^No', action='accept'),
... 'PATCH')

The PUT method can replace an entire header match. The position
key is
optional; if it is omitted, the order will not be changed.
>>> dump_json('http://localhost:9001/3.0/lists/ant.example.com'
... '/header-matches/1',

action: hold
header: x-spam-status
http_etag: "..."
pattern: ^Yes
position: 1
self_link: http://localhost:9001/3.0/lists/ant.example.com/header-matches/1
A header match can be removed using the DELETE method.
>>> dump_json('http://localhost:9001/3.0/lists/ant.example.com'
... '/header-matches/1',
