Thanks for the explanation Eric & Michael, I would like to use SpamDyke, but only very ver conservatively. E.g. if I could block people that I block now (cbl.abuseat.org) during SMTP, that would be great. The other features like greylisting etc., I would not like to use. My own policy (as long as my mail server has the bandwidth to handle it) is to let anything in that *might* be legit. I know that people with wrong DNS setup should not send out mail into the world like that, but I prefer this to just add to their spam score in spamassassin instead of blocking people who just don't know better. (They need educating, not blocking) and it IS hard to explain false positives to endusers... As I explained in a different post, my setup does not throw stuff away, but puts spam into a 'dubious looking' folder and users have to decide what to do with it - which is what they got for complaining about said false positives too often ;-)
Anyway, Is it possible to use SpamDyke for just that? a very conservative DNSBL like abuseat and nothing else??
