i have gotten qpsmtpd polished to the point that i get very little spam, without using any content-level filtering or any externally sourced DNSBLs. I am very happy.
what spam i do get falls into two categories, from recently created free webmail accounts (hotmail/yahoo) or from recently created domains, which have reasonable reverse dns names, real retrying mail servers and spf records. almost universally, when i do a whois on the sender's domain, the registration is only for one year, and was within the last week. whois seems really slow, and the 'license' on the data seems to prohibit it, but has anyone found a way to use that info to block mails until the domain has been around for awhile? i guess there must be a DNSBL for that somewhere? btw, the registrar for these is usually enom.com. allan -- "The truth is an offense, but not a sin"
