...which brings up something I have noticed in discussions about spam: How many people consider "cut down on spam" or "reduce spam" from the POV of spam sent vs. the POV of spam received? In other words, Mr. Anderson seems to be saying "hasn't reduced the amount being sent", and Mr. Rudd is saying "has reduced the amount being delivered to my inbox". Reducing the amount of spam delivered to the user's inbox is good for the user, and is what SA is good at. Reducing the amount of spam actually sent in the first place is good for the entire network community, and a more important long-term goal because it reduces the overall load on the network infrastructure; but it is something that SA and DNSBLs and greylisting and such are NOT (directly at least) achieving. In fact, SA and related tools may be having a detrimental effect overall because they cause the spammers to send that much *more* spam in an attempt to bypass the filters and TMPFAILs and so forth. Reducing volume of spam *sent* probably requires fundamental redesign of the protocols, or some other major change in the cost/benefit analysis. -- John Hardin KA7OHZ ICQ#15735746 http://www.impsec.org/~jhardin/ [EMAIL PROTECTED] FALaholic #11174 pgpk -a [EMAIL PROTECTED] key: 0xB8732E79 - 2D8C 34F4 6411 F507 136C AF76 D822 E6E6 B873 2E79 ----------------------------------------------------------------------- Look at the people at the top of both efforts. Linus Torvalds is a university graduate with a CS degree. Bill Gates is a university dropout who bragged about dumpster-diving and using other peoples' garbage code as the basis for his code. Maybe that has something to do with the difference in quality/security between Linux and Windows. -- anytwofiveelevenis on Y!
