Hi! "The minimum amount of time that postscreen(8) will use the result from a successful DNS-based reputation test before a client IP address is required to pass that test again."
By "successful" ... 1 - Do you mean that postscreen was able to successfully get any data from a dnsbl query - whatever the result was (good or bad reputation)? 2 - Or do you mean that postscreen did get a positive result with (only) good reputation from dnsbl? If 2, is there a way to prevent postscreen from asking dnsbl lists again within an amount of time, means cache (or ttl) for some time the result or the decided blacklist action for the connecting host, whatever the result was (good or bad)? We would like to cache the result - whatever it was - for an hour, because some hosts seem to try again every few minutes or even seconds. Would "postscreen_dnsbl_min_ttl" be the right way? If not, what would be the right way? Only Fail2ban? Thanks, -lutzn _______________________________________________ Postfix-users mailing list -- postfix-users@postfix.org To unsubscribe send an email to postfix-users-le...@postfix.org
