how so, Is it not just a couple of entries in IpTables to redirect all
outgoing destination port 25 messages to the proxy like many people do with
squid on port 80. If all you need to log is source and destination anything
you log out the header is an extra.

The only problem I can foresee is the fact that there are going to end up
being so many blocked ports that you will not actually be able to do
anything new on the Internet again. Hence everything will end up being http
based when http is inapprate because everything else has been blocked.
