SPF, which stands for Sender Policy Framework, is an email protection system, which is employed to validate if an e-mail message was sent by an official server. Employing SPF protection for a particular domain name will prevent the forging of email addresses made with the domain. In simple words: enabling this feature for a domain generates a specific record in the Domain Name System (DNS) which includes the IP of the servers that are allowed to send e-mail messages from mail boxes under the domain. When this record propagates worldwide, it exists on all of the DNS servers that direct the Internet traffic. Whenever a new e-mail message is sent, the initial DNS server it goes through checks if it originates from an official server. When it does, it's sent to the destination address, yet when it does not come from a server part of the SPF record for the domain, it is rejected. Thus nobody can mask an email address then make it look as if you're distributing spam messages. This method is also referred to as email spoofing.
SPF Protection in Shared Hosting
The SPF protection feature is available by default with each shared hosting package that we supply and you will be able to use it with ease so as to protect the e-mails for any domain name hosted as part of your account. The service is controlled from the Emails section of the innovative, yet easy-to-navigate Hepsia Control Panel. All you need to activate the protection is to type the IP of the mail server as well as its hostname - mail.server.com, for instance. When the protection is active, only this server will be able to send e-mails from email addresses created under the domain name that you have picked. Your e-mail addresses may be handled by another supplier, but when we handle them together with your website, you can activate the option for messages to be sent only when the domain features our MX records. This feature will provide you with better protection as only our server will be certified to send out e-mail messages from your mailboxes and you will have better control. If you have any kind of questions or if you have any sort of troubles with this particular service, you'll be able to contact our technical support team anytime and they will give you a hand in a timely manner.
