Appendix D. Closed Private Discussion

ezmlm-make argument string = aBdFgHiJkLMNOPQRSTuWXYZ

Common Uses

This default List Type allows private discussion groups to conduct ongoing conversations without moderator intervention. It is well-suited to the exchange of potentially sensitive information, especially if new subscribers are added by invitation only. Unmoderated mailing lists are more vulnerable to spam, so the number of subscribers is usually kept relatively small. This List Type it is less open and inclusive than the Moderated Private Discussion List Type because it is entirely closed to posts from public senders.

Posting Access

The Closed Private Discussion List Type is unmoderated (the -Mu combination is set in the ezmlm-make argument string), so subscribers can post directly to the list, but messages from public senders are rejected.

Subscription Access

Access is rather restricted in the Closed Private Discussion List Type. Users can't subscribe via email so the subscription process is handled exclusively through web-based tools. The Web Availability setting for mailing lists based on this List Type is usually set to 'Subscribers Only', so that only administrators can add new subscribers to the list.

Setting Use Case Applications
Email Subscriptions
Subscribe via Email? No
Web Availability
Public Not used for private List Types.
Account Holders Only Logged-in account holders can add and remove their own subscriptions. This could work well for an informal discussion list in a small startup organization.
Subscribers Only Administrators have to add new subscriptions. This is used for private discussion lists that want to allow subscribers to leave the list at their own discretion. The most common setting for mailing lists based on this List Type.
Administrators Only Administrators add and remove all subscriptions. This is used for private, mandatory discussion lists or for discussion lists exclusively for administrators. For example, an organization with multiple administrators could find it convenient to use a mailing list to exchange information about administrative issues and enable archiving so the information is automatically stored for future reference.

Archive Access

Archive access is somewhat dependent on the Web Availability setting, since a user has to be able to access the Mailing List Home page in order to see the link to the list archives.

Table D.3. Closed Private Discussion Archive Access

Setting Conditions
Email Archive Retrieval
Messages saved for subscriber retrieval (-aBg) Subscribers have access to the raw ezmlm-idx message archives via email archive retrieval commands. This allows subscribers to retrieve plain text messages only. Email archive retrieval commands from public senders are rejected.
Web Archive Visibility
NO Web Archives Use this if the mailing list doesn't need Web archives. This is uncommon, but could be appropriate for an informal or temporary discussion group.
Public Not appropriate for private lists.
Account Holders Only Can be used only if Web Availability is set to account holders.
List Subscribers The most common setting, matching the most common Web Availability setting. It helps assure that archived list content is only accessed by known, authorized users.
Administrators Only Use when you want archives but don't want them to be visible to ordinary mortals. This setting effectively hides the existence of archives from everyone except administrators.
