Probably an appropriate time for me to mention that one of the activities that the InternetNZ Spam Taskforce is looking at is an easy to access website where ISPs and others can list what spam technologies they use and have available (both at server level and for clients to use).

So the spammers can see what systems that have to beat to get their crap through, no thanks.

I'd happily list on a page that said "These guys do spam/anti virus filtering" so long as I didn't have to say in detail what we did.

People can give as much detail as they want. I would agree you would not want to list for example the exact filters in place (however noting that at http://www.mirror.ac.uk/sites/spamassassin.taint.org/spamassassin.org/tests.... they do list the exact filters and SA works pretty damn well IMO), but detail such as "Use Brightmail", "Use Bayesian Filtering", "Use Spews blacklist" may be useful for consumer choice. Other details I would see as useful if whether the ISP actually filters or just labels so users can filter on the labels. Is the spam filter compulsory or opt-in. Does it cost extra. If they filter is there a spam recovery folder you can check for false positives etc. I actually think it is highly unlikely that with the way spammers work they would try to tailor spam individually for each ISP to get past what they think are its filters. We are not big enough for that. They just throw out 100 million of them and hope say 10 million of them get through and are not too worried if it is 10.0 million or 10.05 million. DPF
