I had a client (this was a long time ago) who'd first installed Exchange 4.x or 5.0 as part of one of those Small Business Server suites. They wanted to upgrade to a full Exchange 5.5 (IIRC) stand alone server. I quoted 4 hours to do the job (chiefly because I never quoted anything less than 4 hours and all my work then was always NTE). The client balked. I told him that if he was going to have his help desk tech do it, make sure he's careful because, for instance, the default for the upgrade is to set the server up as an open relay and they had their exchange server outside the firewall. I was told it wouldn't be a problem because "we're just a little company. No one will know we're on the Internet." Then, two weeks later, the same guy called me in a panic. He said he'd been "interviewed by FBI agents who were interested in all the child porn that was arriving in Australia or somewhere" that had bounced off their exchange server. That mess took me *and* my partner a while to clean up.
