Anti-spam service provider Postini has added sender behavior to its techniques for stopping junk mail. The company is identifying spam sources by tracking in real time the spammer's IP address—the one part of an e-mail message that cannot be spoofed.

Earlier this month, Postini reported that tracking sender behavior had enabled its service to block 53 percent of e-mail connections without having to read the message to determine that it was unwanted.
