Here is what I have in mine (each line separated by a newline for clarity):

dnl Milter-Greylist
INPUT_MAIL_FILTER(`greylist',`S=local:/var/milter-greylist/milter-greylist.sock')dnl
define(`confMILTER_MACROS_HELO', `{verify}, {cert_subject}')dnl
define(`confMILTER_MACROS_ENVFROM', `i, {auth_authen}')dnl

dnl Clam AntiVirus milter
INPUT_MAIL_FILTER(`clmilter',`S=local:/var/run/clamav/clmilter.sock,F=, 
T=S:4m;R:4m')dnl

dnl Spam Assassin milter
INPUT_MAIL_FILTER(`spamassassin', `S=local:/var/run/spamass.sock, F=, 
T=C:15m;S:4m;R:4m;E:10m')dnl
define(`confMILTER_MACROS_CONNECT',`b, j, _, {daemon_name}, {if_name}, 
{if_addr}')dnl

It seems to work perfectly.
