So for a white list i just put in main.cf like this

smtpd_client_restrictions = permit_mynetworks, shadelist.pl -w
nlwhitelist.dnsbl.bit.nl , reject_rbl_client virbl.dnsbl.bit.nl,
reject_rbl_client bl.spamcop.net, reject_rbl_client relays.ordb.org,re$
reject_rbl_client sbl-xbl.spamhaus.org, reject_rbl_client
cbl.abuseat.org, permit

Onderwerp: [ANN] ShadeList: DNS-based white/blacklist policy server

    Some time ago I wrote a simple Postfix policy server to access
DNS-based whitelists. I just put it online at:

     http://www.skopos.be/downloads/postfix/shadelist.html

    It lets you specify any number of whitelists and blacklists. The
latter is useful if you want to apply the whitelist(s) only to selected
blacklists (e.g. the more agressive ones).

    The policy server's reply in case of a hit is configurable. You can
set it to be any Postfix restriction. This can be used, for example, to
apply greylisting to dynamic IP addresses.

    As said, this has been running for some time on a low-volume mail
server. I had meant to make it available to others but ... well, you
know. Since the topic came up recently, I rushed it out and the docs may

be lacking in clarity or contain typo's etc. I intend to do some
polishing in the next few days, but feedback is appreciated.

    Feedback is also appreciated on the functionality of this program,
its implementation etc.

    However, please avoid turning this tread into YAGDARMOx (Yet Another

Discussion About Relative Merits Of X), with X being DNS-whitelists,
mail servers on dynamic IP's, third-party blacklists, operating systems,

programming languages, political parties, hair color/colour, ...

    If this program is useful to you, use it. If not, don't.
