No Default Subscription Properties

None means that a subscriber does not elect to use default transport delivery properties, so no packages are delivered by e-mail or queue. Reasons for selecting this are as follows:

• a subscriber might want to be notified by e-mail about the availability of a package but might not want to receive the contents of the package.

• a subscriber might not want packages delivered by personal subscription but might prefer package delivery only when subscribed to a group.
