Verified usage

Verified import paths — ran on the pinned version, not inferred.

mailman

✓ import mailman

✗ from mailman import core

Top-level import is sufficient; direct submodule imports may break if internal structure changes.

IMailingList

✓ from mailman.interfaces import IMailingList

✗ from mailman.model import MailingList

IMailingList is the interface; model classes are internal and not part of the public API.

Initialize Mailman from config and access a mailing list.

import os from mailman.config import config # Initialize with a configuration file config.load(os.environ.get('MAILMAN_CONFIG', '/etc/mailman.cfg')) # Get a mailing list instance (example) from mailman.interfaces import IMailingList # Assuming a list exists list_name = 'my-list' mlist = config.db.list_store.get(list_name) print(f'List: {mlist.fqdn_listname}')

mailman --version

Debug

Known issues

breakingMailman 3.x is a complete rewrite from 2.x; APIs are not compatible. Do not expect Mailman 2.x patterns to work.

fix

Use the new REST API and library interfaces. See documentation for migration.

affects: >=3.0.0

deprecatedDirect database manipulation is deprecated; use the REST API or the library's public interfaces.

fix

Use mailman.client (REST client) or mailman.interfaces for operations.

affects: >=3.3.0

gotchaConfiguration must be loaded before accessing any components. Forgetting config.load() will raise errors.

fix

Always call config.load('/path/to/mailman.cfg') early in your script.

affects: all
