> No. It would be trivial to cause an innocent system to be listed. Hmmm, true. Would limit its usefulness on a large scale. Still, the idea is to not depend solely on this list but weight it against other factors, like within spamassassin... I'd put in a somewhat short expiry period. I have a theory that many of the machines doing the rumpelstiltskin spamming are hacked zombie windurrr machines. A useful list of confirmed email addresses would be rather large and not lend itself well to packing inside a trojan/worm, a list of common names and some domains would be much smaller... _______________________________________________ TCLUG Mailing List - Minneapolis/St. Paul, Minnesota Help beta test TCLUG's potential new home: http://plone.mn-linux.org Got pictures for TCLUG?
