SPF, which means Sender Policy Framework, is an email safety system, that is designed to validate whether an e-mail message was sent by an official server. Using SPF protection for a particular domain name will prevent the forging of emails created with the domain. In layman's terms: enabling this feature for a domain makes a special record in the Domain Name System (DNS) which contains the IP addresses of the servers which are allowed to send email messages from mailboxes under the domain. As soon as this record propagates worldwide, it will exist on all of the DNS servers that direct the Internet traffic. Any time a new e-mail message is sent, the initial DNS server it uses tests whether it comes from an accredited server. If it does, it's forwarded to the destination address, however when it does not come from a server listed in the SPF record for the particular domain, it's discarded. In this way nobody will mask an e-mail address and make it appear as if you are sending spam. This technique is also referred to as email spoofing.
SPF Protection in Website Hosting
The SPF protection option is provided by default with each and every website hosting
package that we supply and you can use it with ease in order to protect the emails for any domain hosted as part of your account. The service is operated through the Emails section of our revolutionary, and intuitive Hepsia Control Panel. All you need to enable the protection is to type the IP of the e-mail server and its hostname - mail.server.com, for example. As soon as the protection is activated, only this server will be able to send messages from emails created under the domain name that you have picked. Your e-mails may be taken care of by some other company, but when we handle them in addition to your website, you can enable an option for your messages to be sent only if the domain uses our MX records. This solution gives you better security as just our server will be approved to send messages from your mailboxes and you will have superior control. If you have any kind of questions or if you have any sort of troubles with this service, you'll be able to contact our tech support crew anytime and they'll assist you right away.
