Change how people may subscribe to an IU List mailing list

1. Log into the campus IU List website for your list:

   Campus	IU List web interface
   IU Bloomington	https://list.indiana.edu/
   IUPUI	https://list.iupui.edu/
   IU East	https://list.iue.edu/
   IU Kokomo	https://list.iuk.edu/
   IU Northwest	https://list.iun.edu/
   IU South Bend	https://list.iusb.edu/
   IU Southeast	https://list.ius.edu/
   IUPUC	https://list.iupuc.edu/
   University-wide	https://list.iu.edu/

Select My lists, and choose the name of a list.

2. Under "List Configuration", click Change who can (un)subscribe and view list information.
3. If you want people to be able to subscribe themselves to the list using the web interface, under "Who can view list information", you'll need to select for anyone. (You will also need to change the visibility settings of your list to allow non-subscribers to find the list; see Manage your IU List's visibility in the list index.)
4. Under "Who can subscribe to the list", select from the following:
   • subscription request confirmed: Anyone can subscribe, but must first reply to a confirmation message from IU List. This is standard anti-spam procedure for a list.
   • need authentication (notification is sent to owners): As above, but the owner is notified on every successful subscription. This setting is not recommended for large lists.
   • requires authentication then owner approval: After the subscriber confirming as above, the owner must then approve each subscription.
   • subscription is impossible: Subscribing is not possible. This setting must be changed before new subscribers can join.
   • restricted to IU system users: Only users with IU system email addresses are allowed to join the list.
   • for anyone without authentication: Anyone can subscribe to the list without confirmation. This is not recommended, and in all likelihood spamming addresses will end up on your list with this configuration setting.
   • anyone, notification is sent to list owner: As above, but the owner is notified on every successful subscription.
   • anyone, no welcome message: As above, but the subscriber does not receive the welcome message.
   • owners approval: Only the owner can add users, and confirmation is required from the owner.
   • owner must subscribe users, no confirmation required: The owner can add users, but no confirmation is required. This is a weak security setting.
5. At the bottom of the page, click Apply modifications.
