PTR problem with email server
-
I decided I would play around with Cloudron's built in email server, so I enabled it and let it configure the DNS in Digital Ocean. However, there's a problem with the PTR record:
Hostname: <IP>
Record type: PTR
Expected value: my.domain.com
Current value: domain.comI installed Cloudron to the root of my domain, domain.com. Obviously the control panel is available at my.domain.com. How do I configure the r-DNS entry for this? I can't change the r-DNS entry as it's pointing to the root of my domain, which hosts the webmail client.
Thanks

Thanks. I know how to change the r-DNS entry for the VPS. Perhaps my question wasn't the right one.
Is the r-DNS (PTR) only used for email? Ignoring Cloudron, will it cause any problems for any other reason, if I change the r-DNS from domain.com to my.domain.com?

yes PTR are is mainly use, in the case of Cloudron, to validate the mail server
most of mail server will reject your email if they directly come from your cloudron server, if you use a smtp relay you could ignore this -
@YurkshireLad you should rectify your PTR your email will have a better change of being receive.
