Hallo list
Has any one read this:

It sounds very interesting. Without DNS lookups getting most of the dialups.
I have changed on one of my test servers the newest policyd-weight edition
(beta-5) to use that for dynamic host detection:
# http://gabacho.reto.jp/en/anti-spam/anti-spam-system.html
$revhost =~
/^[^\.]*[0-9][^0-9\.]+[0-9]|^[^\.]*[0-9]{5}|^([^\.]+\.)?[0-9][^\.]*\.[^\.]+\..+\.[a-z]|^[^\.]*[0-9]\.[^\.]*[0-9]-[0-9]|^[^\.]*[0-9]\.[^\.]*[0-9]\.[^\.]+\..+\./i
||
The catch rate is very good.
I would as well suggest to add this into policyd-weight to catch even more
dynamic hosts:
$revhost =~
/^(dhcp|dialup|cable|isdn|ppp|adsl|dsl|dial|dynamic|host|pool|port|ippool|static|user|pc|pop|client)[^\.]*[0-9]|^[^0-9]+[0-9]+\.[^\.]+\.adsl/i
||
The above regex catches on my setup by far more dynamic systems then the
original policyd-weight regex.
Maybe adding "^unknown$" and flag them as dynamic would as well not be such a
bad idea. But I don't know.
Has any one else modified his policyd-weight to catch more of the dynamic
systems?
