Hi,Does postscreen_dnsbl_ttl apply to nxdomain responses as well? For example, lets assume an IP lookup on zen.spamhaus.org returns nxdomain and postscreen_dnsbl_ttl is set to an hour - postscreen won't check again for another hour? Or does that caching only apply to non-nxdomain responses.
I do not have access to the recursive resolver so can't really say for sure. Anyone know offhand?
