The PTR and IP address do not match, but I don't know how to fix it.
Email on smtpsvc sporadic and I think from all I read that this is the reason.
I used nslookup to get the PTR and it's 10.10.1.1.
How do I set the PTR to the IP address?
What else will that affect? I don't want to lose connectivity.
This is on Windows 2008 server running Windows Firewall through a router.
I understand ISP has to give me a smart host and that may fix this, but they will not cooperate.
Would it cause this error:
Message delivery to the host '18.104.22.168' failed while delivering to the remote domain 'email.uscc.net' for the following reason: An SMTP protocol error occurred.
