The same thing happened to us (for the first time) a few weeks ago.
No warning of any kind we just suddenly notice that some of our outgoing mail is getting rejected. So I go to the spamcop website to look up our mailserver to see whats going on, and find there is NO information on why we've been blacklisted, just a list of "possible reasons" why spamcop blacklist servers.
If you're interested in being warned when an address in your netblock appears on a DNSBL, try talking to Rick about the service he's running at Alice, as described here: http://www.nanog.org/mtg-0510/wesson.html Also, if can get yourself onto nsp-sec, you'll find there are other similar tools available to you: https://puck.nether.net/mailman/listinfo/nsp-security Neither of these things help you get off lists once you're on them, but at least they give you advanced warning that the problem exists before your customers start telling you about it.
