That is going to happen a lot to some degree. If you're consistently running into it however, you will need to learn how to remove blocks. Some ISP's will help you as long as you do all of the leg work, such as giving you an email account on their domain, or access to their abuse@ email and such. Otherwise, will simply swap them out if they have replacements available or refund you. Keep in mind however, 99% of the ISP's out there do not pro-actively check their IP space nor do they know how to in bulk. We know this as we test IP's for both ISP's as well as direct competitors. Most are completely clueless when it comes to the ip game and matching up unblocked ip space to qualified buyers. A lot of ISP's are making the assumption that ip's become good again and somehow "age off" the BL'gs. While this is true for SOME of the BL's out there, it obviously is not the case with Cloudmark, AOL, etc.. Make no mistake, the ip business whether through an ISP or broker is a thankless business. There is a lot of work and relationships needed to be able to get access to the space in the first place, and then make sure it is 100% clean for whatever it is you need, and more importantly you do not get ripped off by Romanians or alike that just tell you "tough shit" or blame you for burning them up in 2 hours. Understanding this game on the whole will help you make better buying decisions.
In the future try to avoid ISPs that make misleading claims about quality of their IPs. I've seen a lot worse.
While I agree with DKPMO, many times I have bitched to them and as the Mad Hatter said they were unaware of the listings, or trying to pass them on to someone quick, whatever the case and they actually either swap them out giving me a "cleaner" range or did the menial task of removing many of the listings for me, like barracuda, crap like that. Squeaky wheel... The different types of listings are the key, and to what domains your mailing also important. Many minor listings don't even effect delivery, others kill you right out the box.
I do not think dirty ranges are bad per se, it is just whether the seller is upfront about what they are providing and willing to fix things when they are not right, instead of making up obviously false or incompetent excuses. I am sure anyone who has been in this business for awhile has seen the full spectrum of The Good, The Bad and The Ugly. You just have to make you own determination of whether you believe your vendors are competent and trustworthy. Just to be clear I am not familiar with details of this particular case, nor do I want to insert myself into a dispute of 3rd parties. This is just my general advice on paying close attention to who you are doing business with.
