WEB HOSTING - configuring an "announce-only" mailing list in Mailman


Logging in to the control panel
You will first need to log in to your account control panel via the login panel on the hosting home page using your domain administrator user name and password as provided.

Click on Mail icon

select the >>> Mailing Lists link then [ add mailing list ]

Following is how to create a mailing list for announcement purposes only, so that subscribers to the list cannot post to it but only receive email from it.

A combination of Moderation and Privacy settings are used to lock the list down.

1: General Options:

> In General Options, scroll down to the bottom of the General list personality section and set the Hide the sender of a message, replacing it with the list address option to Yes.
> In the Reply-To: header munging section, set the Where are replies to list messages directed? option to This list.
> Scroll down and click the Submit Your Changes button.

2: Subscription / Advertising Options:

From the Configuration Categories list at the top, click on Privacy Option. The Subscription rules options will display below.
> In the Advertise this list when people ask what lists are on this machine? choose No.
> In the What steps are required for subscription? section, choose Require approval.
> Set the Who can view subscription list? option to List admin only.
> Click the Submit Your Changes button.

3: Moderation Options:

From the Configuration Categories list at the top, click on Privacy Option.

> Click on Sender filters.
> In the By default, should new list member postings be moderated? section, choose Yes.
> Change the Action to take when a moderated member posts to the list option to Discard.
> Scroll down and set the Action to take for postings from non-members for which no explicit action is defined to Discard.
> Set the Should messages from nonmembers, which are automatically discarded, be forwarded to the list moderator? to No.
> Click the Submit Your Changes button.

4: Adjust Moderaton Options for Specific Members:

You'll need to turn off Moderation for anyone who will be generating email announcements for the list, as well as make sure Moderation is turned on for everyone else:

> First, set any existing subscribers (if there are any) so they're moderated:
> From the Configuration Categories list at the top, click on Membership Management. Your current list of subscribers will be displayed.
> At the bottom of the page, in the Additional Member Tasks, set the Set everyone's moderation bit, including those members not currently visible option to On.
> Click the Set button.
> Scroll down the list of subscribers and uncheck the box in the Mod (first) column for anyone who will be sending announcements to the list. (If they're not already subscribers, add them)
> Click the Submit Your Changes button.

That's It! Your list is now setup so:
>> The sender of announcements is hidden.
>> Replies go to the list (and are later discarded.)
>> Your list is not displayed on https://www.lists.pdx.edu.
>> People cannot subscribe themselves automatically.
>> Only list Admins can view the subscriber list.
>> All non-subscriber postings are discarded.
>> All subscribers, present or future, are moderated EXCEPT for the subscribers sending announcements.
>> All moderated mail is discarded.
