Hi all,
I've been running pf+obspamd on FBSD 6.2-RELEASE.
I appear to be blocking some addresses that appear in my spamd-mywhite file
and I don't understand why that would be the case here. I'm guessing I've
screwed up my pf.conf file.
Here's my config file:
# pfctl -vvnf /etc/pf.conf
ext_if = "rl0"
int_if = "xl0"
internal_net = "192.168.1.1/24"
external_addr = "216.70.250.4"
vpn_net = "10.8.0.0/24"
NoRouteIPs = "{ 127.0.0.0/8 192.168.0.0/16 172.16.0.0/12 10.0.0.0/8 }"
webserver1 = "192.168.1.4"
set skip on { lo0 }
set skip on { gif0 }

spamdb doesn't show any entries for 205.188.159.7.
These entries are for AOL mail. I've received complaints from AOL users of
mail bouncing back to them.
What am I doing wrong? Are CIDR records accepted by pf+obspamd? I can't
trace the block back to the proper rules- i.e. rule 3/0 as shown in pflog0
matches up with which rule in pf.conf?
Any suggestions are appreciated!
