Open Lists
The characteristics of an open list are:
- Anyone can post to the list by addressing mail in the form of listname@domain.com .
- If is turned on in the List Security page, all list posters must enter a password to post to the list.
- The option does not affect open lists. If this option is selected, anyone will still be able to post to the list whether they are in the posters list or not.
