you have to study its parameters ( they may differ by version and distro ) http://linux.die.net/man/1/spamass-milter i use it like /usr/sbin/spamass-milter -P /var/spool/postfix/spamass-milter/spamass.pid -f -p /var/spool/postfix/spamass/spamass.sock -f -e -x -I -u vmail -r 15 -i 127.0.0.1 i have my spamassassin setup with mysql for users self settings use i.e.e webmail horde with sam module, or something equal with i.e squirrelmail or roundcube but i managed it before ,also in using local files with maildrop as i said ,its not ideal cause of pre queue design, but reality shows good enough for big isp setup and it may be combined > > I am using clamav-milter.
