Dear experts, Our Imail server can't send email to a few large corporates' recipients. At last, with the help of Scott, I find the root of the problem, our mail server's IP don't have a PTR record. That means that you can't use our mail server's IP to do a reverse DNS search. Some recipients' mail server will reject the mail if they can't do that to verify the sender's identity. Now, our new problem is that we can't create a PTR record for our mail server's IP. I have try my best to do it. But failed. Our ISP create a PTR record on their DNS server. It does work, but ONLY on their DNS server. We don't know why our PTR record can't spread to other DNS servers in the world. I also try to apply for a new domain name, then create a PTR record for it. I buy one at www.domainbank.com at the cost of $35.-. Then we pay $10 for creating DNS record on their DNS servers. But, at last they told us they can create MX and A record for us, and they can't create a PTR record for us. I am in despair. I have no idea about what I should do next.
Maybe somebody know where we can create PTR records. Anybody, who can give me some suggestions, would be greatly appreciated! Thanks in advance!
