I've been subscribed to the list for about 4 months, and I searched through my locally saved messages for topics of this nature, but couldnt find any.. So forgive me if someone has publicly announced this revelation.. Also forgive the cross-posting; I want to get a bunch of input.
I am working on a program that will scan mail with "X-Spam-Status: Yes" in the header, and determine the last host who sent it to me was. I am then going to insert that IP into my mail system's denied host list (to give some permanent error to the sending host). A cron is going to run to dymajically determine when my mail server should start accepting mail from that server again. While coding, I had a thought... Would it be a good idea to Auto-White list/Auto-Black list Mail Servers themselves? While most of us don't have access to MAPS, it might be a good idea. So if SA has gotten -- i dont know -- 20 legitimate emails from a certain host, then that host is white-listed for ~30 days (with each additional day getting a good email extending the expiration a day) if SA gets a few SPAMs, it is auto-black listed (with some expiration) And, not to clutter your minds, but what if we substituted the Host-Based AWL/ABL with Ratings? If an email came from a host in the "Good Servers" list, give it a score of -2; if the host is in the "Spammer Servers" list, give it +2. The only downside I can see is that the allow/deny database could get quite big and rather quickly for bigger mail servers. But if a bigger mail server is using SA in the first place, they've probably got the CPU to spare.
