Client A GroupWise client is a full-featured client that can access a GroupWise user's mailbox at a post office.
ConsoleOne Is the primary administrative tool for many of Novell's products, GroupWise included.
Domain Database Every domain database has a name of WPDOMAIN.DB. The GroupWise snapins to ConsoleOne must connect to a WPDOMAIN.DB in order to allow an administrator to administer the GroupWise system. MTAs and gateways also require connectivity to the WPDOMAIN.DB. Updates to the WPDOMAIN.DB are made either by the MTA or the GroupWise snapins to ConsoleOne.
Gateway GroupWise supports a variety of gateways. The most popular gateways are the GroupWise Internet Agent (GWIA) and the GroupWise WebAccess gateway. The GWIA allows for SMTP messaging across the Internet. The GWIA also supports other protocols such as IMAP and POP3. The GroupWise WebAccess gateway allows browser and wireless device access to GroupWise.
GDS GroupWise Directory Store. The GDS is contained within domain databases (WPDOMAIN.DB) and post office databases (WPHOST.DB). Changes to the GDS are made by the GroupWise snapins to ConsoleOne, with the snapins connected to a WPDOMAIN.DB. When changes are made, they are replicated to the rest of the GDS by the MTAs and the POAs in the GroupWise system.
Mailbox The GroupWise environment and messages that are accessible via GroupWise clients, or other standards-based clients such as POP3 or IMAP4 clients.
MTA Message Transfer Agent. Every GroupWise domain has an MTA associated with it. An MTA routes messages and processes administrative updates to a domain's WPDOMAIN.DB database.
POA Post Office Agent. Every GroupWise post office has a POA associated with it. The POA routes messages in and out of a post office.
The POA also processes updates to a post office's WPHOST.DB database. GroupWise clients or processes that access a GroupWise mailbox do so by getting a connection to the POA.
Post Office All GroupWise user's mailboxes are associated with a post office. Many other objects must also be anchored to a post office object, e.g., resources and distribution lists. In a GroupWise system most of the action and data retained is at the post office level.
Post Office Database Every post office database has a name of WPHOST.DB. Changes to the WPHOST.DB are only made by the post office's POA. The POA requires connectivity to the WPHOST.DB. The WPHOST.DB acts as the authentication database for a post office and the address book for GroupWise clients.
Primary Domain The primary domain is the main administrative replication hub for changes in the GroupWise system. Every GroupWise system has one primary domain. All administrative changes to the GroupWise Directory Store (GDS) are replicated to and through the primary domain. The primary domain cannot relegate it's function to any other domain in a GroupWise system, but it can perform all the functions that a secondary domain can.
Secondary Domain Since there is only one primary domain in a GroupWise system, all other domains are considered secondary domains. Technically, there are other domain types, but that's beyond the scope of this discussion. As a GroupWise system expands and grows, particularly across wide area networks, it is necessary to create secondary domains. All domains are serviced by an MTA that routes messages in and out of the domain.
SMTP Simple Message Transfer Protocol. This is the Internet-based protocol that allows for exchanging electronic messages in a standard manner.
Snapin The primary administrative tool for many Novell products is ConsoleOne. GroupWise is administered through ConsoleOne with the help of GroupWise-specific snapins. These snapins are designed to display and administer GroupWise objects correctly.
