A known spammer had a box co-located at my providers network. Within 48 hours of their colocation the whole ISP was blacklisted by spam filters around the world that follow spammers. The guy didnt spam anyone yet, but the groups who do the monitoring and spam filters for the blacklists (relay) cought wind of his move.
So when checking for a host, its wise to check the hosting companies IP address with the spam relay blacklists. Now most every message I send out gets bounced back saying that the block of IPs is blacklisted.
The hosting co. took the guy off the network and is trying to resolve this. But this has made business truly hard for communication when all you do is e-mail the people.
I just had a similar issue with a client blocking incoming email spam. They ended up including their info@ email addresses in the spam filter and were wondering why they were not getting any contact requests from their sites!

Most of the people just have you put in the IP address to see if its been tagged. Open Relay Database (ORDB) and OsiruSoft Open Relay Spam seems to be the lists that have effected us.
I saw a stat recently that 11% or so of e-mail gets lost, mostly due to crude spam filtering. If you are a company doing online billing or similar mission-critical activities, that has to be a huge headache.
I've checked out web hosts in USENET abuse discussions, but is there any central place to check to see if your potential new host could be blacklisted?
