All we can tell for sure is that quite a lot of spam currently comes direct from consumer Internet feed address space. Possible sources include: - People who manage to configure open relays or open proxies, either through poorly designed software, or user incompetence. These people get relay-raped. - Spammers who buy Internet feeds, use them until they get caught, and then fade back into the woodwork. - Users who unintentionally run spam-relay software. These include Trojan software (the game that also sends spam or whatever), "click me" worms that depend on the user, and self-propagating software that attacks vulnerable software. - Users who intentionally run spam-relay software, because the spammers claim (truthfully or not) they will pay the users for doing so. > The SPF approach seems to have the goal on making DNS-based blacklists > reasonable, not addressing the spam-from-a-virus problem. SPF prevents spammers from spoofing a domain that does not want to be spoofed. That has value by itself, as it means you can now whitelist on selected "From" addresses reliably. It is unlikely SPF will actually stop spam. -- Ben Scott <[EMAIL PROTECTED]> | The opinions expressed in this message are those of the author and do | | not represent the views or policy of any other person or organization. | | All information is provided without warranty of any kind. | _______________________________________________ gnhlug-discuss mailing list [EMAIL PROTECTED] http://mail.gnhlug.org/mailman/listinfo/gnhlug-discuss
