It's possible too, I was misslead when you use the word redirection. It could be your router (provided it is based on a Unix box (or Windows box :)) or any place where all your internet traffic is going through. A nice location is where one would usually install an IDC. The "tee" functionality beiong done with a simple hub. Then the box silently listen at every packets and does this or that with the packets. If the box is sitting between X and Z (like a router) it can then decide to abort the connection. >Let's just imagine for example that this thing is a little black box >with no storage, maybe just a few meg of RAM.

Whether it is SMTP or POP/IMAP traffic makes little difference (only difference is to tell the box what to listen to), but how would you install the box at a place where you can be sure the user will have to run it's internet connection through it (except if the user is you)? And also if the box is close to the user, it means that to check the mail, it has already transited through Internet (sometime through dial-up lines) so the network bandwidth is already wasted. And also consider the way SA works (you are supposed to know better than I do :) if I understand well, it needs to read all the message, then process it, then send the result, right, there is no way SA is working in a pipe-line, on a partial message (say 1024 bytes at a time). Now your magic box could even be your Linux box, running your POP/IMAP client in fact.
