Never ever would I do that! I would suggest you to look for something like policyd-weight and/or postfwd and combine a bunch of RBL/RHBL/WHL and other mechanism to mitigate the failure of one single lookup list.
For postfix users, I would second, without any reservation whatsoever, the use of policyd-weight. No one RBL will cause a block; you can add others to the default configuration as you desire. You'll find that you are blocking a huge amount of spam *before it hits your mail queue*, which means a massive reduction in server resources used (less work for dspam) not to mention more or less eliminating problems like rejection notice bounce back and the like. A single perl script and one configuration file - nothing could be easier. Is in FreeBSD ports if you are a user of that OS or direct from the web site. I've customized the script somewhat; I don't allow certain conditions to pass as readily, and I've integrated a patch which allows Geo IP lookups. As our users do not do much business with certain spam producing haven countries (notably VN, BR, CN), I set the bar high for mail senders in that country - guilty until proven innocent, as opposed to the default, innocent until proven guilty. All in all policyd-weight is a simple and hugely effective tool. So effective that I can shut off dspam if need be and for the most part, many users would not even notice. In fact for our purposes, the only thing dspam is used for is tagging (and integrated clamav scanning). That in no way diminishes dspam's value to us... the tagging feature (with delivery) is important to us. What little spam makes its way through the postfix / policyd-weight gauntlet I do want tagged, but delivered (dovecot sieve places this potential spam in a junk dir), and that's dspam's mission for us. ------------------------------------------------------------------------------ Let Crystal Reports handle the reporting - Free Crystal Reports 2008 30-Day trial.
