What an ordeal. I have a security camera system that sends email alerts. I used to send via Google, but they tightened up their security and I cannot use that any more. I figured I'd just set up a simple mail server on an RPi and do it myself. My ISP provides a static IP I can set up pretty much anything I want. I bought a domain name through hover.com for the purpose, and set up A and MX records in their DNS.
I finally got my mail server figured out and working and try to send email to my normal account, which is promptly rejected by my email provider (IONOS) for a bad PTR record. (Mail does go to my gmail account without complaint.) I go into the dashboard for my domain to set the PTR record, and there is no option. I contacted tech support and get "Sorry, we do not support PTR records. You will need to host your DNS with a 3rd party." What he heck kind of domain registrar who provides DNS services does not support PTR records? Been browsing the Internet for DNS providers, and can't find anything that tells me what they support. The few who I contacted said basically, "Sign up for our service to see what records we support." Seriously? It's been like 15 years or more since I did this kind of stuff. Got to learn it all over again. Anybody have suggestions on a free or cheap DNS provider that I can set PTR and any other needed records? Thanks, Michael
