I recently wrote a script to automate spam complaints to the contact address(es) of the previous hop before my mail servers, using both a Whois lookup by IP address (see Net-Whois-IP-0.35 Perl module, available at CPAN) and a DNS SOA lookup. It's quite effective, except for sites within RIPE, which doesn't list "abuse" contacts in any easily automatically parsable way, as far as I can tell. > ...

Caching would definitely be a requirement, both to reduce the impact on the Whois servers, and to limit the performance impact on the receiving mail servers. My own systems have already been slowed down enough by all the filtering that users are complaining. > Anybody care to offer suggestions? I would prefer to see something like this not tied to the Bayesian filter, for selfish reasons: I'm not in a position where I could effectively perform Bayesian filtering, given the amount of mail my systems handle, for the number of users they handle mail for. Realistically, I could use Bayesian filtering for a subset of these users, and I may still resort to that (with the expectation that the subset in question would grow to become a majority), but at the moment I prefer not to "privilege" those users more than others. -- ---------------------------------------------------------------------- Sylvain Robitaille [EMAIL PROTECTED] Systems analyst Concordia University Instructional & Information Technology Montreal, Quebec, Canada ---------------------------------------------------------------------- ------------------------------------------------------- The SF.Net email is sponsored by EclipseCon 2004 Premiere Conference on Open Tools Development and Integration See the breadth of Eclipse activity.
