Colleagues- Has anyone seen a large up tick in the past 24hrs of residential ISP's handing out IP addresses that are blacklisted? We're in Northern NJ so the popular ISP's are Verizon FiOS, Comcast, and CableVision and we've received at least 20-30 calls to our help desk this morning regarding email submission errors due to IP blacklisting. I've seen this happen now and again for a user or two, but never such a large group of users at the same time. Thanks, Jeff Giacobbe Associate Vice President Enterprise Technology Montclair State University
