If a part of the ISP's network is on a spam list, and the mailop mail server is on the same IP block, there are two issues here, 1) the issue of the difficulties in reaching out the filter (in this case Microsoft) and other filters still unknown, and the lengthy process, if at all responsive, of rectifying the false record. This is not easy. 2) How does one ask for an IP address or a small block, as a new block that is not a part of, nor in the vicinity of, a contaminated block? Or if it is a reassigned IP address, how does one ask the RIR / NIR to check the past history of the IP address block that is being reassigned (like how to verify the service history of a used car) ?
