markmnl It seems very few providers reject for reverse PTR, is it worth setting up?
If you want to send emails reliably, then yes, absolutely. You can’t always choose where to send emails, nor can you choose which email provider a recipient uses. Also, it may work with a provider today but won’t necessarily work tomorrow if they change things and become more restrictive.
markmnl Would having a reverse PTR setup help my spam score - mail-tester results below:
Yes, the overall score in the testing tool will improve. However, I’m not sure if it affects the SpamAssassin score on this specific test site. If I’m interpreting your screenshot correctly, the issue seems to have something to do with the DMARC policy.
That said, the absence of a PTR record can affect the spam score depending on the ruleset used by the recipient’s mail server. Once again, this is beyond your control, so if you want reliable email delivery, I’d highly recommend following email best practices.
