I have been running qmail + vpopmail + qmailscanner + spamassassin + clamav for a while now. While some spam is caught our detection rate is not great.
My qmail uses ordb and spamhaus and dsbl for rbl checking. I am using pretty much stock spamassassin rules. The only thing that is changed is it uses mysql for per user preferences. How can I improve our detection? What recommendations does the list have? Thanks, _ /-\ ndrew
