Sorry, not a direct CentOS question, but I know there's a lot of experienced users on this list...I'm using CentOS with sendmail and spamassassin. I've got it configured with spamass-milter and it is working correctly. However, I was expecting to be able to reject mail that is marked as spam, not just deliver it as usual. Anyone know if it can be done and how? I know a milter can reject mail, because I've used milter-grelist in the past to give temporary fail messages.
Following is my sendmail.m4 directive for spamass-milter:
INPUT_MAIL_FILTER(`spamassassin', `S=unix:/var/run/spamass-milter/spamass-milter.sock, F=, T=C:15m;S:4m;R:4m;E:10m')dnl define(`confMILTER_MACROS_CONNECT',`t, b, j, _, {daemon_name}, {if_name}, {if_addr}')dnl define(`confMILTER_MACROS_HELO',`s, {tls_version}, {cipher}, {cipher_bits}, {cert_subject}, {cert_issuer}')dnl
