I want to use FC3 to setup a mail relay/spam filter using sendmail so that my Exchange server doesn't talk to the world anymore! In essence I want sendmail to talk to the outside world, run a spam and virus check on the incoming mail and then relay it to the Exchange server; and then do the same for outbound mail. Can someone point me to a FC3/Sendmail HOWTO on getting this done? It's been a while since I've messed with sendmail stuff like this? Thanks! :b! Brian D.
