I am seeing a lot of email bouncing from my server... the bounce messages indicate that the IP does not have reverse DNS set up, but I can see valid rDNS records when I query it on my local machine. I know I set the rDNS records at least four days ago, so I am sure any TTLs would have expired. What could be causing this and how can I troubleshoot?
The server's IP is: 184.108.40.206
Here is a sample bounce message, with email addresses removed:
