Selfhosted
A place to share alternatives to popular online services that can be self-hosted without giving up privacy or locking you into a service you don't control.
Rules:
-
Be civil: we're here to support and learn from one another. Insults won't be tolerated. Flame wars are frowned upon.
-
No spam posting.
-
Posts have to be centered around self-hosting. There are other communities for discussing hardware or home computing. If it's not obvious why your post topic revolves around selfhosting, please include details to make it clear.
-
Don't duplicate the full text of your blog or github here. Just post the link for folks to click.
-
Submission headline should match the article title (don’t cherry-pick information from the title to fit your agenda).
-
No trolling.

I don't know what to tell you. I'm literally looking at my DNS records at cloudflare that point to my home IP and there is no PTR entry and yet I have dozens of emails in my gmail account about scheduled process and Prometheus alerts etc. The last undeliveryable I got from Gmail was 2 month ago when I was setting up the email server. Maybe because I'm on Google Fiber it's not enforcing it but I have no PTR record.
PTR records are NOT on the domain side.
https://www.cloudflare.com/learning/dns/dns-records/dns-ptr-record/
An example record lookup would be
8.8.8.8.in-addr.arpa. Like I've said twice now. YOU don't control google's PTRs (since you linked to google workspaces). They DO have PTRs setups.IP of 142.251.2.109 resolved for my DNS.
https://easydmarc.com/tools/ptr-record-lookup?domain=142.251.2.109&dns_server=1.1.1.1&dns_type=PTR
Resolves to a record name of
dl-in-f109.1e100.netEdit: Another name for a PTR record is rDNS. Or Reverse DNS. and that name is a bit more descriptive in that it's IP -> Name rather than DNSes normal job of Name -> IP address
I don't use Google Workspaces that's just the first article I found.
Maybe I misunderstood then. I though PTR records had to resolve to your email domain, not just match the IP address with an A record that resolves to the same IP. There is a PTR record that resolves to ip.googlefiber.net but it does not match my email domain.
