SpamAssassin with Postfix

[JimmyJ]

Hello All,

I have Plesk 9.0.1 on CentOS 5 as a Virtuozzo VPS. This plesk does not come with psa-spamassassin so I wanted to install spamassassin myself. I followed the instructions on http://netweblogic.com/linux/mail/qmail-scanner-linux-plesk/ and everything went successfully. But I am still getting tons of spam. Checking the logs I don't see where spamd is being called at all. What I want is to rewrite the Subject of every incoming email with ****SPAM**** if spamassassin gets 5.0 hits on it. I guess the problem is that postfix is the actual mail agent that is getting the email so how do I get postfix integrated with SA on this VPS? I played around with /etc/postfix/master.cf to call "spamc -e" as per http://wiki.apache.org/spamassassin/IntegratedSpamdInPostfix. I could see that SA was evaluating emails but no emails were getting delivered at all. My master.cf has this in it:

smtps inet n - - - - smtpd -o smtpd_proxy_filter=127.0.0.1:10025 -o smtpd_tls_wrappermode=yes

Can anyone help me get this working?? Thank you.
