I was wondering if anyone with a VPS and properly configured DKIM and SPF records has successfully managed to avoid getting the Reverse DNS (PTR) error messages similar to the following within Cpanel's Email Deliverability:
The system uses an alternate HELO of “s111-111-111-111.secureserver.net” when sending mail from the “mydomain.com” domain.
The system sends this domain’s outgoing mail from a private IP address, “99.999.99.99”. Reverse DNS does not work with private IP addresses because DNS does not store PTR records for them.
The server may be misconfigured.For more information, contact your system administrator.
