This is a thread from the same question I asked on the spamassassin mail list.
Has anyone gotten the 3 fore mentioned milters working together?
SA and clam work but greylist does nothing. no errors, no added
headers just nothing.
if i take out clamav from the mc then greylisting works and SA works
but not all three together.
parts of sendmail.mc in question. (in order)
greylist:
INPUT_MAIL_FILTER(`greylist',
`S=local:/var/lib/milter-greylist/run/milter-greylist.sock')dnl
define(`confMILTER_MACROS_CONNECT', `j, {if_addr}')dnl
define(`confMILTER_MACROS_HELO', `{verify}, {cert_subject}')dnl
define(`confMILTER_MACROS_ENVFROM', `i, {auth_authen}')dnl
clam-milter:
INPUT_MAIL_FILTER(`clmilter',
`S=local:/var/run/clamav-milter/clamav.sock, F=, T=S:4m;R:4m')dnl
define(`confINPUT_MAIL_FILTERS', `clmilter')
SA:
INPUT_MAIL_FILTER(`spamassassin',
`S=local:/var/run/spamass-milter/spamass-milter.sock, F=,
T=C:15m;S:4m;R:4m;E:10m')dnl
sry if this is too much of a sendmail centric question - I thought i
would w/ the server admins here first.
thx

Why would you expect headers from greylist? Here's the evidence that
shows up that the greylisting did it's thing:
Aug 3 00:37:56 mailgate sendmail[29267]: k730bkG7029267: Milter:
to=<myuser at example.com>, reject=451 4.7.1 Please try again later
(TEMPFAIL)
Here are the relevant lines from my .mc
INPUT_MAIL_FILTER(`relaydelay', `S=local:/var/run/relaydelay.sock,
F=,T=S:1m;R:2m;E:3m')
INPUT_MAIL_FILTER(`clmilter', `S=local:/var/run/clamav/clmilter.socket,
F=,T=S:4m;R:4m')
INPUT_MAIL_FILTER(`spamassassin', `S=unix:/var/run/spamass.sock,
F=T,T=C:15m;S:4m;R:4m;E:10m')
You might need to check your maillog file to really get to the bottom of
why it doesn't seem to be working.

Thanks, I think I got it - i noticed you didn't have the clamav line
define(`confINPUT_MAIL_FILTERS', `clmilter')
so i took it out and clamav-milter seems to be working fine w/ out it.
re: headers - milter-greylist writes a new header line "Sender IP
whitelisted, not delayed by milter-greylist-1.6..." or whatever.
what do you use for the delay or wait time and auto whitelist time?
thx

Huh! I don't think I've ever noticed that-- I'll have to go see if I can
find that, maybe it will serve some additional purpose in a spamassassin
rule.

Unfortunately, I had to disable the default "delay all triplets that
you've never seen before", because we had too many (misconfigured, IMO)
other sites with extremely abnormal queue retry periods (12 hours? give
me a break!), and that created a lack of faith in our email system
despite the huge spam reduction that resulted.
While it was set up to delay, I found that 5 minutes was very
sufficient.
