Milter-greylist

Hello,

I'm using milter-greylist for some time now. It runs on 3 FreeBSD 9.x servers with Amavisd-new as a before queue content filter (ie. Postfix in Proxy).
This setting prevent milter-greylist from accessing headers and content of email messages. Hence, it can't add the X-Greylist header when the message is passing through.

I need to get some info about the way milter-greylist is delaying messages. Unfortunately I'm unable to retrieve this info.

My configuration is looking like this:

-------------------
pidfile "/var/run/milter-greylist.pid"
socket "/var/milter-greylist/milter-greylist.sock" 660 
dumpfile "/var/milter-greylist/greylist.db" 600
dumpfreq 1
user "mailnull:mail"
geoipdb "/usr/local/share/GeoIP/GeoIP.dat"
stat ">>/var/milter-greylist/greylist.log" \
     "%T{%Y/%m/%d %T} %d [%i] %r -> %f %S (ACL %A) %Xc %Xe %Xm %Xh\n"

verbose
quiet

list "my network" addr { ... }
list "broken mta" addr { ... }
list "whitelist domain" domain { ... }
list "grey users" rcpt { ... }

racl whitelist list "my network"
racl whitelist list "broken mta"
racl whitelist list "whitelist domain"

racl greylist default delay 2m autowhite 15d
-------------------

First time a new message comes in, I have proper notification in logs (postfix logs, milter-greylist logs, debug.log thanks to "verbose", and special "stat" log file):
"bypassing greylist", "autowhitelisted for another 360:00:00", "delayed for 00:02:00", and so on.

But when the message comes back later and is accepted, milter-greylist fails logging any info. It's just mute, and I don't know how long the message was really delayed.

Any idea?
thanks,
