Absolutely correct. Andrew, as much as I can disagree with you on some things, I would stick to your guns on this one and tell the client that the recipient mail server has to be fixed, as it is extremely poor to reject an e-mail based on a single blacklist, and worse to reject based on a minor black list at that.
