Captchas apparently help quite a bit to stem this kind of problem because they install a technical barrier that, while not impossible to break through programatically, at least delays things a bit and reduces the ROI for the spammer.

Captchas are all fine and dandy but they are not ADA compliant and certainly a no-no for government or public agencies. Don't believe me? Accessibility issues (Section 508) will be the next Y2K obstacle for IT folks because all of our future software purchases require that the software is accessible. Within the next 18 months we'll have to provide a VPAT [example: http://www.section508.nasa.gov/vpat3.htm] for all software purchases. If your company doesn't know about these yet kiss goodbye to all your government customers. As for catching spam and viruses we gave up on open-source solutions a long time ago in favor of IronPort appliances. These products negate almost 100% of your effort in maintaining greylists or rulesets. You have plenty of choices out there with very different approaches and you can bet the top-tier companies like MailChannels, IronPort, and Mirapoint (among others) have something to make your life easier. matthew black network services california state university, long beach 1250 bellflower boulevard long beach, ca 90840-0101
