Hi Folks, For PTR records out there that are pointing to domains other than those that you control, I’m looking to understand common practice around their setup. Two questions:
1. In general, can I trust PTR records? Is ownership of the target domain validated at setup time by ISPs, and if yes, how is this done? 2. If ownership of PTR targets is not routinely validated, is there a risk that the target domain could be blacklisted by anti-spam providers? Thanks, Stephen Malone Microsoft ________________________________ About Microsoft Ireland: www.microsoft.com/ireland Microsoft Ireland Operations Limited.
