Monitoring e-mails in GroupWise 7.0

I am a district-level administrator with a school district in Arkansas
and we notify our employees that e-mails may be monitored for
inappropriate use. However, my Technology Director tells me that
GroupWise doesn't have this capability because e-mails aren't "retained"
in any way, such as in a server, etc. Prior to installing GroupWise a
few years ago, we used networking software from another company and we
did have that capability.

I'd like to know if there IS a way to monitor e-mails through GroupWise
and how we can obtain the ability to do so.

Thanks.
