I use both a blacklist file and DNSRBL's. Domain names are a pretty easy list to collect, since they are basically static. IP addresses are continually changing. It's much easier to use one of the many DNS based blacklists than it is to try to keep an up-to-date list of your own. Spammers will continue using the same domain names for months, or even years. IP addresses are basically fleeting, disposable commodities. You would think that spammers would just use a domain name once or twice, then dispose of it, since domains are relatively cheap to purchase nowadays. My own logfiles prove otherwise. I wouldn't be using this domain list unless it was catching a significant amount of spam each day, and it does. Combined with the use of DNS based blacklists and some well-written iMail rules, you can easily block 90%+ of spam. If you add Bayesian filtering, such as ASSP provides (I have never had good luck with iMail's internal Bayesian filtering), you should be able to stop at least 98% of spam. Of course, it's that last 1-2% that is the toughest to catch, which is where a product like Declude or IMGATE really helps out. William Van Hefner Vantek Communications, Inc.
