Hi,
I am trying to protect my mailserver from spam with pf and spamd and have
run into some problems. My mailserver sits on my LAN protected by my
3.3-current firewall. The firewall redirects smtp, web, and so on to the
appropriate machine on the lan, my smtp rdr is as follows:
rdr on $ext_if proto tcp from any to $external_addr/32 port 25 -> $mailserver port 25
Now this works, but I wanted to implement spamd on the firewall as well. I
set up the following rules (I've tried having them both before and after
the afformentioned rule):
table <spamd> persist
no rdr on { lo0, lo1 } from any to any
rdr on $ext_if inet proto tcp from <spamd> to any port smtp -> 127.0.0.1 port 8025
and I've poppulated <spamd> with addresses from relays that have spamed me,
however none seem to have ever gotten caught in my trap. (and I know that
I've recieved spam from the same relay more than once). Am I missing something
obvious, or is this just not possible?
