The 'Resolved Fail' issue is not a concern. It simply means that a reverse lookup could not be performed on the client IP due to its status as a private IP address. This has no impact on the mail flow whatsoever.
This is an expected behavior for private IPs, unless the local DNS server is configured to include PTR records for the clients' IP addresses.
