Post Office Agent

The Post Office Agent (POA) is the GroupWise program that delivers messages to users'
mailboxes in each post office. In addition, the POA detects and repairs damaged databases,
replicates shared folders between post offices, performs the indexing tasks of document
management, and responds to requests from Remote client users.

Message Transfer Agent

The Message Transfer Agent (MTA) is the GroupWise program that routes messages between post
offices, domains, and gateways. In addition, an optional message logging module of the MTA can
provide logging and statistics data about GroupWise message traffic.

Async Gateway

The Async Gateway is the GroupWise program that enables asynchronous communication
(through modems and telephone lines) between domains on the same GroupWise system or
between domains in separate GroupWise systems. It also allows remote GroupWise users to access
their Master Mailboxes through modem communication.

Process 1: User Sends Message

The user sends a message from the GroupWise client, then the POA delivers the message to the
MTA.

Process 2: MTA Queues Message

The MTA queues the message to the Async Gateway.

Process 3: Async Gateway Transfers Message

The Async Gateway in the sender's domain transfers the message through a configured modem
and phone line connection to the receiving Async Gateway located in the recipient's domain.

Process 4: Async Gateway Queues Message

The Async Gateway in the recipient's domain queues the message to the MTA in the recipient's
domain.

Process 5: MTA Queues Message

The MTA queues the message to the POA.

Process 6: POA Updates Message

The POA updates the message database and the recipient's user database.

Process 7: POA Generates Message Status

The POA generates a Delivered status message and queues it to the MTA.
