PostOffice Relay

The PostOffice Relay is an email transport method in which email is registered in the IBM® Rational® ClearQuest® database, which prevents loss of email messages.

This transport type is implemented by using the ClearQuest EmailRelay service. With the PostOffice Relay, email messages are stored in the ClearQuest database. Therefore, they cannot be lost even if the relay service goes offline. When the relay service restarts, the service resumes where it stopped, and delivers all the outstanding emails.

This illustration depicts how EmailRelay in PostOffice Relay mode is architected.

The ClearQuest Web server communicate with the ClearQuest EmailRelay server using PostOffice Relay. The ClearQuest Web client communicates to the ClearQuest Web server through a browser. The ClearQuest EmailRelay sever communicates through the optional firewall to the email server.
