Option | Key | Roles | Definition |
|---|
Closed | closed | Moderator: no
Owner: no

Moderated | editorkey | Moderator: yes
Owner: yes, moderator approved
Subscriber: yes, moderator approved
Non-subscriber: yes, moderator approved | Anyone may send to the list, and their messages get flagged for moderation. List moderators may send straight to the list. |

Owner: yes, moderator approved
Subscriber: yes, moderator approved

Restricted to local domain | intranet | calpoly.edu only | Anyone whose address ends in calpoly.edu may send messages to the list. |
Restricted to local domain and subscribers | intranetorprivate | calpoly.edu & subscribers | Anyone whose address ends in calpoly.edu or anyone who's subscribed to the list may send messages. This can be useful for when you want a more open list without opening it up too widely for spammers. |
Newsletter, restricted to moderators and owners | newsletter | Moderator: yes
Owner: yes
Subscriber: no
Non-subscriber: no | Only list owners or moderators may send messages to the list. This is most useful for announcement-style lists, where you want a select group to be able to broadcast messages out to all the list members, without anyone else being able to contact the list. |
Newsletter, restriced to moderators after confirmation | newsletterkeyonly | Moderator: yes, verified
Owner: yes, verified
Subscriber: no
Non-subscriber: no | Similar to the newsletter send scenario, this one only allows owners or moderators to address the list, and it sends them back a confirmation message asking them to make sure they want to send that message to the list. It also prevents people from being able to falsify messages to the list by setting their mail client up to claim to be one of the moderators. |
Restricted to subscribers | private | Moderator: yes
Owner: yes
Subscriber: yes
Non-subscriber: no | Only list owners, moderators, and subscribers may send messages to the list. This is the standard default for non-public lists as it prevents spammers from sending messages out to the list. |

Owner: yes, RD5 required
Subscriber: yes, RD5 required
Non-subscriber: no | Only list owners, moderators, and subscribers may send to the list, and they all require valid S/MIME signatures. S/MIME signatures are specialized attachments that verify, through the use of a trusted third party, the sender's identity as being authentic and the message as being unaltered. This is the most secure setting for your list, but all the users on the list must have valid S/MIME signatures |
Moderated, restricted to subscribers | privateandeditorkey | Moderator: yes

Owner: yes, moderator approved
Subscriber: yes
Non-subscriber: yes, moderator approved | Subscribers and moderators may send messages straight out to the list. Non-subscribers' messages will be flagged for moderation.

Owner: yes, verified
Subscriber: yes
Non-subscriber: yes, verified | Subscribers may send messages to the list, as may users whose S/MIME signatures can be verified.
