My guess is that it's not the HN page itself but their MTA that is configured probably to restrictive. It's probably something in your domain config (SPF, DomainKeys set right?). If this would be your own mailserver you could easily check if an attempt is made but fails out of some other reason. Now, the only thing to check is someone from HN in the mail relay log files or someone from google in their logs ;) In the end, i would bet that you missed some step in setting up your domain that needs to be done for Google Apps :)
