I did not notice anything in the documentation about how Antivirus systems
work with GW Mobile. Since this is a valid conduit into the GroupWise
system, at what point do emails get scanned?

If you have a Real Time Antivirus (Like Symantec or Kapersky) on the GW
Mobile server, does it scan the message from the mobile device before
delivery to the POA and vice versa?

Or do you have to have an AV client on the mobile device? I know Symantec
has a client for the Microsoft Mobile Desktop 5.
