SPF, which is short for Sender Policy Framework, is an email security system, which is designed to verify whether an e-mail message is sent by an authorized server. Employing SPF protection for a given domain name will prevent the forging of emails made with the domain. In layman's terms: enabling this attribute for a domain name creates a particular record in the Domain Name System (DNS) which includes the IP addresses of the servers that are allowed to send emails from mail boxes using the domain. As soon as this record propagates globally, it exists on all the DNS servers that direct the Internet traffic. Whenever some e-mail message is sent, the first DNS server it goes through checks whether it comes from an approved server. When it does, it is forwarded to the destination address, but when it doesn't come from a server indexed in the SPF record for the particular domain, it's rejected. Thus nobody can mask an e-mail address then make it appear as if you're e-mailing spam messages. This technique is also known as email spoofing.

SPF Protection in Cloud Hosting

The SPF protection feature is provided as standard with each cloud hosting package that we offer and you're able to use it without difficulty to protect the e-mail addresses for any domain name hosted as part of your account. The service is handled through the Emails section of our cutting-edge, yet easy-to-use Hepsia Control Panel. What is needed to activate the protection is to type the IP address of the email server in addition to its hostname - mail.server.com, for example. The moment the protection is activated, only this server will be able to send out messages from email addresses made under the domain name that you've selected. Your emails can be handled by some other provider, but if we handle them together with your web site, you may also enable the option for your messages to be sent only when the domain uses our MX records. This selection will provide you with greater protection as just our server will be approved to send e-mails from your mailboxes and you'll have improved control. When you have any questions or in case you have any troubles with this particular service, you can contact our technical support team at any time and they'll assist you without delay.
