As an example, if Spamhaus doesn't have nice things to say about the block, it's time to start asking questions.... http://www.anti-abuse.org/multi-rbl-check/ has a fairly good list of places that could give your customer a bad time (whether or not the listing is deserved - the point is that being listed anywhere there will probably mean problems that have to be cleaned up) You may all now begin the religious war over where else to check.
