Using the ELA CoS, the administrator defines which users can use the enhanced list application (ELA) feature. Users can use the ELA feature to create distribution lists for delivering messages to a large number of recipients. ELA associates one mailbox to a list of members, so that when users want to send a message to the whole list, the users can send a message to the list mailbox instead. When a new message is delivered into the list mailbox, known as the shadow mailbox, ELA distributes the message to the members of the list. ELA members can be local or remote users.
