2. Once logged in, navigate to List Management > List Configuration.

3. In the Select List drop-down menu to the right, then choose the list you would like to manage.

4. Click the Subscriptions button.

5. Scroll down to the Send section and locate the Special field.

7. In the Special field, enter the email addresses of non-member, non-owner senders you wish to allow.

• To allow another L-Soft list to send: enter (OTHERLIST)
