SPF, which is short for Sender Policy Framework, is an e-mail security system, which is designed to validate if an e-mail message was sent by a certified server. Using SPF protection for a given domain name will prevent the forging of email addresses generated with the domain. In layman's terms: activating this feature for a domain name makes a specific record in the Domain Name System (DNS) containing the IP of the servers that are permitted to send email messages from mailboxes under the domain. The moment this record propagates globally, it exists on all DNS servers that direct the Internet traffic. Any time some email message is sent, the first DNS server it uses checks whether it originates from an approved server. When it does, it is sent to the destination address, yet when it does not originate from a server indexed in the SPF record for the particular domain, it is discarded. In this way nobody will mask an email address then make it look as if you're distributing spam messages. This technique is also called email spoofing.

SPF Protection in Shared Website Hosting

The SPF protection feature is provided as standard with each shared website hosting package that we offer and you can use it without difficulty to secure the e-mail addresses for any domain name hosted as part of your account. The service is controlled from the Emails section of the outstanding, and easy-to-navigate Hepsia Control Panel. All you need to activate the protection is to type the IP address of the mail server as well as its hostname - mail.server.com, for example. Once the protection is activated, only this server will be able to send e-mail messages from e-mails made under the domain that you've selected. Your email addresses may be handled by another supplier, but when we handle them in addition to your web site, you can enable an option for email messages to be sent only if the domain uses our MX records. This option provides you with even better protection as just our server will be certified to send messages from your mailboxes and you will have better control. When you have any kind of questions or in case you have any troubles with this particular service, you can contact our tech support team anytime and they'll give you a hand right away.
