Ip is not a public IP
FAIL All WWW IPs public Error: At least one of your WWW IPs is not a public IP. The problem IP(s) are:
72.36.140.10 is not a public IP
That means that some or all people trying to get to your web site will not be able to get there.
What this mean ?
FAIL Acceptance of postmaster address ERROR: One or more of your mailservers does not accept mail to postmaster@tinhbuonthienthu.com. Mailservers are required (RFC822 6.3, RFC1123 5.2.7, and RFC2821 4.5.1) to accept mail to postmaster.
tinhbuonthienthu.com's postmaster response: >>> RCPT TO:<postmaster@tinhbuonthienthu.com> <<< 550-test.dnsstuff.com (test.DNSreport.com) [69.2.200.182] is currently not 550-permitted to relay through this server. Perhaps you have not logged into 550-the pop/imap server in the last 30 minutes or do not have SMTP 550 Authentication turned on in your email client.
How to fix its?
