narramissic writes "In a recent article, security guru Brent Huston writes about research he did to get inside the minds of spammers and expose some of the processes they use to identify potential targets. Huston says that among the four common ways that spam is spread, the most common method that spammers use is via open relays. Huston's research also revealed that 'they were doing much more server analysis' than he had expected and that they take a multi-step approach: 'They scan the server for proper RFC compliance, and then they send a test message to a disposable address. Only after these are complete did they adopt the tool to dump their spam.'"
