This settings page is only available to Domain Administrators, Mailing List Administrators and System Admininstrators with the proper permissions.
Mailing Lists are a great way to allow users to communicate with a number of different individuals via a single email address. For a complete understanding of how mailing lists work, please see Mailing Lists Overview.
List Administrators, Domain Administrators and System Administrators (with the proper Manage Domains permissions) can restrict the posting privileges for a mailing list to Anyone, Subscribers Only or Moderators Only. In addition, they can use the Posters section to specify additional list subscribers who can post messages to the list -- these special subscribers are considered "Whitelisted" as they've been given special permission to post messages, in addition to, say, Moderators Only.
To add additional posters to a mailing list, log into SmarterMail as an Administrator (List, Domain or System) and go to the Settings area based on your role. Then click on Mailing Lists in the navigation pane and open a mailing list's configuration options. Then click on the Posters tab.
To add a new poster, click New. Enter the email address(es) of the people who can post messages to the mailing list.
In addition to manually adding new subscribers, it's possible to upload a text file that contains subscriber emails and any Custom Fields assigned to your subscribers. Text files should be in Comma Separated Value (.CSV) format.
Of course, since you can upload a subscriber list, you can also download one. This is especially convenient if the subscribers for one list -- or a subset of those subscribers -- is interested in another list you start up. Downloading your list subsribers, then editing it if needed, makes it simple to add subscribers to a new list.
It's also possible to keep a list of users who are banned from posting to your mailing list. You can import subscribers to this list as well as download that list to use in others you've created. For more information, see the section on Banned Users.
