POST-INSTALL: Rules are no longer included with SpamAssassin "out of the box". You will need to immediately run "sa-update", or download the additional rules .tgz package and run "sa-update --install" with it, to get a ruleset. Be careful to run sa-update before calling /etc/rc.d/spamassassin. Otherwise you may receive this error: child process [1101] exited or timed out without signaling production of a PID file: exit 255 at /usr/bin/spamd line 2588. in this case remove the /tmp/spamd-*-init directories, run sa-update and only after that start spamassassin.
