Three Folders with Seven Messages
The message retention application reads the existing time stamp (May 7, 2007 12:00:00) and selects
a time between that time and the current time. For example, suppose the current time is May 9, 2007
14:00:00. The message retention application could choose May 8, 2007 12:00:00 as the new time
stamp. It would then retain any messages delivered between the existing time stamp (May 7, 2007
12:00:00) and the new time stamp (May 8, 2007, 12:00:00).
In the above example, messages 1, 4, and 6 are older than the existing time stamp (May 7, 2007
12:00:00). The message retention application would not retain these messages again, assuming that
they had already been safely retained. Messages 2 and 5 have dates that fall between the existing
time stamp (May 7, 2007 12:00:00) and the new time stamp (May 8, 2007, 12:00:00) so they would
be retained. Messages 3 and 7 have dates that fall after the new time stamp (May 8, 2007, 12:00:00)
so they would not be retained until the next time the message retention application ran against the
mailbox.
33.2 Acquiring a Message Retention Application
If you do not already have a message retention application to use with GroupWise, you have two
options: 1) you can purchase an application from a GroupWise partner or 2) you can develop your
own application.
For information about GroupWise partners that provide message (e-mail) retention applications, see
the
Partner Product Guide (http://www.novell.com/partnerguide) .
For information about developing a message retention application, see the GroupWise Object API
and GroupWise Trusted Application API documentation at the Novell Developer Kit Web site (http:/
/developer.novell.com/wiki/index.php/Category:Novell_Developer_Kit) .
33.3 Enabling Message Retention
This section assumes that you’ve installed a message retention application as a GroupWise trusted
application and that it is configured to provide a message retention service. If not, see
Section 4.12,
“Trusted Applications,” on page 69 .
