You want to look at Email Invalid Cause or Hard Bounced data. Not every bounced record will have helpful information here, but some will tell you if your shared IP was blacklisted or if you were marked as spam at that firm. It might just say blocked though.
I would focus on automating the blocking of anyone who hard bounces x2 and soft bounces x3 in 30 day period. Don't worry about the reasons.
Josh (sorry to hikack), but how would I find if someone has blacklisted our IP address? Can this be done as a Bounced smart list?
