It has been a long time since I had last used SpamAssassin but the level of spam I was receiving had taken a decided uptick.
So I decided to reinvest some time in that tool a week or so ago.
Pleased that that local SpamAssassin installation has been having great success in weeding out the ever more clever spammers since I decided to go into full geek mode and add caching name server support to my local network too so that SpamAssassin can make use of its network tests.
An hour later and bind is configured and the DNS lookups are humming.
