SpamFilter does not cache any DNS queries. We make the DNS queries via the operating system, and leave the caching up to the DNS resolver on the server running SpamFilter and on the DNS servers themselves.]]> Mon, 25 Feb 2008 21:10:48 +0000 https://www.logsat.com/spamfilter/forums/forum_posts.asp?TID=6399&PID=11749&title=how-long-caches-sf-nameserver-lookups#11749 <![CDATA[How long caches SF nameserver lookups? : Hi, is there any setting to...]]> https://www.logsat.com/spamfilter/forums/forum_posts.asp?TID=6399&PID=11748&title=how-long-caches-sf-nameserver-lookups#11748 Author: kp4711

Hi,
 
is there any setting to tell SF how long it should cache a nameserver-lookup?
It seemed to me, that SF cache a lookup for a while, it is possible to disable this behaviour?
regards
