Stopping Spam E-Mail:
SPAM is a world-famous canned luncheon meat from Hormel Food. Internet spam isn't—it's junk e-mail. Spam e-mails are the unsolicited advertisements you receive that try to sell you a college diploma, pheromones that women can't resist, or pornography if those pheromones don't work. I'm sure you know what I mean because everyone attached to the Internet gets tons of this stuff.
One of your tasks as the administrator of a mail server is to reduce the amount of junk mail moving through the network. The techniques used for that task are the topic of this section.
