What is the difference between a User list and a Customer list?
A User list is a list which can only be used by the particular Xpedite user id which sent the list to the Xpedite Service. A Customer list is a list which can be used by any user id registered with a particular corporate customer of the Xpedite Service. Note that a change made to a Customer list will change that list for all of the users who could use it.
