I have SA running with Postfix running with Amavisd and Razor. In the short time (a little over a day) that we have had this running, we have noticed a dramatic reduction in spam with the default settings specified in the Scott Henderson setup document we used. Are there any other databases/addons that would be suggested to use ? I don't want to over engineer it but want to do the best job possible at blocking spam.
These are the "optional" features for SA that I like and use (not in any order)
razor 2.61 or higher
http://razor.sourceforge.netdcc
get package from http://www.rhyolite.com/anti-spam/dcc/surbl, using the Mail::SpamCopURI addon in SA 2.6x, or the default support in 3.0
If you need spamcopURI, get it from http://sourceforge.net/projects/spamcopuri/
DNSBL support, using the Net::DNS module
Just install the perl module with CPAN or packages.Antidrug.cf
cd /etc/mail/spamassassin
wget http://mywebpages.comcast.net/mkettler/sa/antidrug.cf
spamassassin --lint (to check for errors)
restart spamd
Disclaimer: I wrote antidrug.cf, so I am biased. Also note that versions of these rules are built into 3.0, so delete it when you upgrade.
