> 
> Firstly disable RulesDuJour
>     chmod -x /etc/cron/daily/rules_du_jour_wrapper
> Now it won't run every night.
> 
> Next, delete all the rulesets downloaded by RulesDuJour, as 
> we're going 
> to use sa-update to get them instead. We don't want 2 copies of the 
> rulesets.
>     rm -f /etc/mail/spamassassin/*sare*cf
>     rm -rf /etc/mail/spamassassin/RulesDuJour
> 
> Create a file for your list of SpamAssassin 'channels' including the 
> default set. Attached is a file to drop into 
> /etc/mail/spamassassin/jkf-channel-list.txt. Note that this is my 
> *personal* set of SARE rules that I use on my servers. I 
> strongly advise 
> you go to www.rulesemporium.com and read the descriptions of all the 
> rulesets and adapt the file to your own personal requirements.

>     wget http://daryl.dostech.ca/sa-update/sare/GPG.KEY
>     sa-update --import GPG.KEY
> 
> Next we need to add some command-line arguments to the call

> SAUPDATEARGS to say
> SAUPDATEARGS="-D --channelfile 
> /etc/mail/spamassassin/jkf-channel-list.txt --gpgkey 856AA88A"
> (That should all be on one line of course)
> Once you are happy everything is working, remove the "-D" and it will 
> run a lot more quietly.

> If you are using MailScanner 4.62.1 or earlier, then edit 
> /etc/cron.daily/sa-update and/or /etc/cron.daily/update_spamassassin 
> and/or /usr/sbin/update_spamassassin to make sure the call to

> /etc/cron.daily/KAM.cf.sh and make it executable:
>     chmod +x /etc/cron.daily/KAM.cf.sh
> Run it once to get the initial copy of the ruleset file. It 
> will keep a 
> backup copy of the KAM.cf ruleset in KAM.cf.backup, which it 
> will use if 
> it can't download KAM.cf correctly later.
> 
> That's about it.
> I hope this improves the effectiveness of your spam checking.
