| TECHNICAL REQUIREMENTS FOR E-MAIL DELIVERY
Reverse DNS
The reverse DNS is a resource that allow others servers to verify the authenticity of your sever, verifying if the actual IP address matches with the IP address informed by de DNS server. This avoid that someone uses a domain that doesn’t belong to him for spam mailing.
Anyone can send e-mails by putting in the sender field the server of your domain, but one server configured to verify the reverse DNS will find out the and classify the forged e-mails as spam.
Servers configured to verify the reverse DNS will refuse e-mails, or classify them as spam in case of the DNS server isn’t correctly configured to answer to the reverse DNS verifications.
Actually we arrived to a point that the spam problem is so severe, that almost all the servers do this checking, making that, without the configuration, approximately half of your e-mails don’t be delivered.
You must request to your provider to configure the reverse DNS of your domain.
