# Category 16: Master Distribution Lists Feature Bits

These feature bits allow the system administrator to create and use master distribution lists. They also allow a user to make messages for a Master List and to receive Master List messages. Master Distribution Lists are stored in the administrator’s mailbox and designate groups of mailboxes that a user can send a single message to. Master distribution lists are available to any mailbox with the appropriate feature bits, listed below. There are 99 master lists available. Master distribution list numbers use two leading zeros. To address a message to master list 1, enter 001. For master list 99, enter 0099.
