I've been getting more spam recently so I did sa-update for the first time in a year (I thought it was automatic :-()).
I restarted the spamassassin service (Ubuntu). $ /var/lib/spamassassin$ ll total 16 drwxr-xr-x 4 root root 4096 Oct 15 2011 ./ drwxr-xr-x 45 root root 4096 Jun 12 06:40 ../ drwxr-xr-x 3 root root 4096 Aug 27 2011 3.003001/ drwxr-xr-x 3 root root 4096 Sep 21 23:59 3.003002/ Will it use the latest rules or do I need to delete the older ones? Where in a mail header does it say what version of the rules it used?
