* This is the modus mailing list * If you've been on this list very long you know that one of my pet peeves are the RBL's that are run by people who think that they are the net police. They do stupid things and blacklist entire networks or domains for bizarre reasons. There are blacklists that will blacklist a domain just because they have x number of complaints about them, problem is, a lot of those domains are being spoofed and the spam is not originating from them. An rbl has to be careful to insure that its blacklistings are reasonable, reliable and are actually blacklisting the right network and not spoofed domains etc.
One of the real great things about a dynamic blacklist is that it blacklists the originating ip of the spam, regardless of the domain name or anything else. And the even nicer thing is that it also dynamically releases that ip from the blacklist without intervention from anyone after a set amount of time. It is reasonable because a mail server will not be blacklisted unless spam is actually, and currently, being sent from that server, it is reasonable because it will release the server from the blacklist once the spam run is over or keep it there if it continues. Even if the originating network were to complain, the defense is that you will stop the blacklist once they stop the spam. We have used it for about 8 months now and I can attest to the accuracy and effectiveness. If you want to see the results from one of our servers showing the banned ip's and their release times you can view it at: http://icarus.access-one.com/cgi-bin/ip_ban_check.cgi.

More specifically, they list Covad DSL customers. Although Covad sells business packages with static IPs and subnets for the purpose of running servers, it makes it rough as those ranges are listed and blocked with a bad assumption about their network. ** To unsubscribe, send an Email to: [EMAIL PROTECTED] with the word "UNSUBSCRIBE" in the body or subject line.
