This procedure describes the nesting of a distribution list within a distribution list. It also describes how to prevent mailbox owners from nesting distribution lists.
To nest a list:
Specify the list as a member of the list being created or modified.
Make sure the number of a nested list is different from the number of the distribution list that contains it.
To prevent nesting, customize an FCOS to include feature bit 222 (deny nesting of distribution lists) and assign it to the required mailboxes.
