get yourself registered on feedback loops.  aol, comcast, earthlink, 
usa.net, and maybe some others offer this.  then you'll get copies of 
email they consider to be spam.  by using them as early warning systems, 
you can avoid getting on the blacklist in the first place.  also, make 
sure you have a valid email address set on your ip whois info so that 
abuse messages can get to you.  get registered with abuse.net.  
basically do as much as you can so that you're aware of what complaints 
are being generated and can shut off abusers more quickly.

robtex.com is a good site to use to check for blacklist entries.  you 
might be able to run a wget via cron to watch things daily.
