Hi all, Looking for some help on troubleshooting postscreen…
I was recently reworking the list of rbls that I use with postscreen and realized that quite a bit of spam that was getting through was in fact on enough blacklists to hit my postscreen threshold. I’m not seeing anything obvious in the logs (checking the dnsblog entries), and I’m not sure where to start. I’d really like to get full logging of postscreen and all dnsblog activity for a few minutes - is it possible to see all queries and their results? I’m not seeing a way to increase verbosity while perusing the dnsblog or postscreen manpages. If I’m hitting some odd resource limit (I have like 18 rbls setup), will some piece of postfix complain about that? Maybe some internal caching is why I’m seeing things pass (I’m very specifically looking at very fresh spamhosts). More generally, anyone have any tips/advice on troubleshooting beyond Postfix? I’m pointing all my rbl queries at an instance of dnscache (which is admittedly quite old, probably abandoned)… Recs on a lightweight dnscache replacement? Thanks, Charles
