but unfortunately the two/four lookups with
host ${RECEIVIP2REV}.zen.spamhaus.org
host ${RECEIVIP2REV}.list.dsbl.org
are very slow...
My idea was already if I do not direct filtering, I could catch the IPs,
put it into a cache file, sort and unify it and use an independant
process which fetch the status and write out a file, which I can easyly
import into my own DNS server (bind9) @home and then do the final
filtering
On my <samba3> I have with the Quad-Xeon enough resources to install
some instances of bind9 as VHosts which could be setup as
<zen.spamhaus.org> and <list.dsbl.org> which then would be deactivated
if <samba3> get an internet connection...
Question: Is it possibel to get (FTP) the lists from the two servers for
private non-public use? If yes, how big are they?
dsbl was rsync-able but is now gone. for spamhaus, you would have to pay
a fee (too expensive if you don't receive a lot of mail).
Since I am only 2-3 times per week On-Line, it would be nice
if I could fetch the whole list. (I asume this takes less
resources as making several 1000 lookups on the DNS)
It will reduce the latency of your "real time" checks, but will
certainly increase the overall bandwidth usage (if you add up the sizes
of the dns packets, the result will be much smaller than that of the list).
