> Currently I am blocking all mails from = *.nl *.br *.ch etc.. That's fun, we're blocking each other! Most spam here in the Netherlands comes from the US.. We block almost everything from China, Korea and Taiwan in postfix based on domain-name and on ip-range (mostly complete B-classes). But also a lot of other domains/ips are blocked like comcast, rr, verizon, brasialian ips, dynamic*, dialup*, indeed some .jp domains, etcetera. And all dynamic/dialup addresses in dynablock.njabl.org and dul.dnsbl.sorbs.net are blocked. The spamstats from spamcop.net shows the popular spam ip-ranges: http://www.spamcop.net/w3m?action=map;net=bmaxcnt;mask=16777215;sort=spamcnt
