How the spammers find youHow the spammers find youPosted Apr 28, 2003 15:42 UTC (Mon) by Klavs (subscriber, #10563)Parent article: How the spammers find you Instead of just blacklisting mailservers that send SPAM - they should be reported to SPAM-Cop or some other spam-stopping initiative - so they will be warned that they are blacklisted and perhaps do something about it. Another way that I believe will work to stop spam (If enough people do it) would be to have the mailserver scan the spam while the DATA is being written - and if it seems to be spam - don't acknowledge it was received - disconnect the sending client (so it'll try again) and drop a iptables rule rewriting connections from that IP to port 25 to your local tarpit (a program that keeps mailserver connections open forever - thus wasting their capacity. This would be great if enough users did it - because then the mail-servers would much more easily be maxed out in their memory capacity - and the owners would notice their servers not sending their own mail - and be (I should think) be much more interested in dealing with the problem. What do you think?
