3 Mailing Lists
Mailing lists distribute a single email message to multiple recipients. Mailing lists differ
from workgroups in a few fundamental ways. First, mailing lists aren’t linked to file or
directory permissions. Mailing lists can be administered by someone other than the
workgroup or server administrator. More importantly, mailing list subscribers do not
have to have any kind of account (mail or file access) on the list’s server; any email
address can be added to the list. Finally, list subscribers can often remove themselves
from lists, and add themselves to lists.
Mac OS X Server uses Mailman version 2.1.2 for its mailing list service.
Some of Mailman’s main features include (from www.list.org/features.html):
• Web-based list administration for nearly all tasks, including list configuration,
moderation (post approvals), management of user accounts.
• Web-based subscribing and unsubscribing, and user configuration management.
Users can temporarily disable their accounts, select digest modes, hide their email
addresses from other members, and so on.
• A customizable home page for each mailing list.
• Per-list privacy features, such as closed-subscriptions, private archives, private
membership rosters, and sender-based posting rules.
• Configurable (per-list and per-user) delivery mode.
• Integrated bounce detection within an extensible framework
