Great idea! I also had some problems with attacks from other networks and the sysad there did not seem to be intersted in that his servers are being abused for attacking other systems. But instead of a mailinglist I'd propose some kind of a public index of those networks (like those openrelaydatabases). How about thta??
Negative. If people/network admins really use this database, then it can be easily used as a DoS against someone an attacker doesn't like. In addition, it violates the victim's right for privacy (would you like to be listed there if someone broke into your mailserver and started hacking from it?). Another problem: Even if you don't relay spam through the world, you might end up on the ORBS blacklist, just because you might happen to not meet all criteria that they impose (happened to me several times). In this case, the problem might even get out of control: "Message suppression" is a serious crime in Germany, and with methods like this you're walking along a very thin line...
