Since you didn't provide your domain name, I can't troubleshoot for you.

I recommend reading my comment https://news.ycombinator.com/item?id=14720344 and following the troubleshooting steps I outlined.

We use the news.pariyatti.org domain for these emails. If you're willing to help troubleshoot, that would be much appreciated. Otherwise I'll try to work through your recommendations, although a lot of it is very new to me so I'm not sure how far I'll be able to get. You can reach me via email at my HN username @pariyatti.org if you wish to discuss further.
