automatic mail scanning software

I was just cleaning up my office, throwing out a bunch of vendor literature from a recent unixexpo, when a flyer for a product called "MpScan" from an outfit called "CyberSoft" caught my eye. This product, as advertised, "automatically searches outgoing email for company classified material". Aside from being configurable to do stuff like block mail to certain addresses, it also " ...uses the powerful, user-tested CVDL scanning language..." and can generate "...reports which can be used to look for unusual changes in Email usage...". A "version 2" promises "many more feaures using an AI engine". All this can be yours for only $49,000 per mail server, or $200,000 per site license. You get free upgrades until the end of 1997. -matt
