My employer and I went through a miserable series of similar events when a third-party reseller for BellSouth suggested that we upgrade our DSL service. Upon installing a higher-speed DSL line into the building (which had the effect of frying our DSL router since the new connection was in reverse polarity to what we'd had earlier), we were told that we'd need a new series of static IP addresses because the existing ones were, for some reason, not compatible with the new service.
We consented to the change, knowing that we'd lose email and some other services for a few days while the new IP addresses became recognized across the net, but were stunned when our email started getting bounced by most of the large ISPs. It turned out that the new range of static IPs they'd allocated for us was actually in a group that was reserved for residential customers, so the blacklist managers assumed that there shouldn't be servers running on them. After much arguing with the blacklist managers, the ISPs and BellSouth, none of whom had any interest in speaking to each other about the situation, BellSouth finally changed our IP range again - right back to the range we'd had originally, without explanation or recourse for the thousands of dollars in lost manhours and business we absorbed over the issue. The resellers who started this, of course, stopped returning phone calls the day after our old IP range had been restored. My best advice would be twofold: if you can find out from where Insight's getting its blacklist service (there are two or three primary sources out there, I'll try to dig up their locations from my old notes), see if you can find out from them why UofL got on the list; you might also check with UofL's IT and see if there have been any changes to the IP locations of the mail servers, since most blacklisting is done by IP address rather than by domain (at least in my experience).
