Depots A depot is that portion of a TRANSFER database associated with a particular
correspondent. The depot is established when an application registers the
correspondent with the TRANSFER delivery system. Every correspondent has
precisely one depot and that depot has a network-unique identity, which an
application references implicitly through the correspondent name. A depot contains:
Distribution lists
A profile
Folders
Distribution Lists A distribution list simplifies the delivery of a package to multiple correspondents. The
list can contain the names of correspondents, interest groups, and other distribution
lists. By using distribution lists, an correspondent can send packages to multiple
destinations while referring to those destinations with one name. As long as a
correspondent knows a particular distribution list name, that correspondent can
remain unaware of the specific names on the list.
Before the TRANSFER delivery system delivers a package to the correspondents on a
distribution list, that list must be expanded. To expand the list, the TRANSFER
delivery system replaces the referenced distribution list name with the names of the
correspondents on the list. These correspondents are known as the members of the
distribution list.
Profiles A profile is a set of one or more records that describes the correspondent who owns
the depot. These records reside in a profile file, which contains the profiles for all
correspondents registered at the node. The records are managed by the TRANSFER
delivery system. There are two types of profiles:
A correspondent profile contains:
Identifying data, such as the password of the correspondent and operational
parameters applicable to the correspondent.
Privileges of the correspondent
The default values for package delivery parameters, such as delivery priority
and expiration time
An agent profile for a depot contains:
The name of the agent or agents that should be invoked when a package
arrives at the depot.
Selection criteria for invoking the agent
Other information, such as whether the agent is a SCREEN COBOL requester
program or a server.
The TRANSFER delivery system also manages profile records for Tandem mail clients
and any other applications requiring storage of data applicable to the depot.
