compromised on for minimum user impact but are still quite effective.

peer <other server>
peer <other server>
peer <other server>
peer <other server>
peer <other server>
syncaddr * port 7689

acl whitelist addr 127.0.0.0/8
acl whitelist addr <our netblock>/16

report all
delayedreject
Lazyaw
dumpfreq 10m
timeout 2d
greylist 10m
autowhite 32d (keepps monthly newsletters etc. in the list)
subnetmatch /24
pidfile "/var/run/milter-greylist.pid"
socket "/var/milter-greylist/milter-greylist.sock"
dumpfile "/var/milter-greylist/greylist.db"
user "milter"
