We have a network mail server provided by our internet provider. 25 Win98/NT machines send POP3 mail directly to the providers server. We need to be able to snoop and monitor all emails leaving the office. We have 2 Linux Boxes, A Samba server and a router box. We also have 2 NT Servers... I need to setup some sort of system where the 98/NT machines can connect to the POP3 server where the mail will be carbon copied to a email moderator before being sent to the ISPs server...
How can this be accomplished?
I have heard of smart servers but I don't fully understand, nor do I know where to start.
