Oops... sorry, forgot to mention that we're running 2.6.1 (19007) but I believe that this has been a problem with version 2 for a while.
---------- My messages don't seem to be making it to the list so I'm trying again after refreshing my list settings. My apologies if this is a duplicate. We're noticing some emails which are pretty obviously spam and are listed on DNSBLs like Spamhaus Zen but are making it through anyway. Looking at the log, RBL checks are not being done on these emails. We're using a local caching recursive DNS resolver (unbound) and it's working fine, but what seems to be happening is the messages pass some sort of check like DKIM or SPF, and then they seem to get the all clear without doing the RBL checks. If they fail the DKIM check or there's something else that scores against them, then DNSBL/URIBL checks are done. So it seems that all a spammer really has to do is properly sign their spam emails coming from wespamyou.com and the Jedi mind trick is complete. "There's no spam to see here, move along." I'm not seeing any settings relevant to this that would seem to change this behavior, is there something I'm missing? Also, on a semi-related note, is there a setting that allows you to cache DNSBL misses like URIBLCacheIntervalMiss does for URIBLs, or does that setting also apply to DNSBLs as well? Being able to cache misses for just 5 or 10 minutes could significantly reduce query traffic for sites with lots of mail traffic without a huge or lasting impact on accuracy. Thanks!
