Stoopid mail client

Hi,

I’ve got a potentially huge issue with email that I need some help on. We’re using Netscape as our mail client, on NT4SP6a machines with a Netware 5.1 server. The problem is that Netscape picks up the time and date from the client pc when sending emails. So you could have a situation where someone sets their date to some date in the past and claims to have sent a mail at a time when they didn’t. (if you know what I mean).

So far, the users and managers are unaware, but when they do find out, there’ll be hell to pay.

Is there a way to lock down the time and date so that users can’t change them? Will this interfere with sync’ing from the Novell server?
Is there another option I haven’t considered?

Thanks in advance,
Gary
