SPF, which stands for Sender Policy Framework, is an email protection system, which is employed to verify whether an e-mail message is sent by an official server. Using SPF protection for a particular domain will prevent the faking of emails made with the domain. In layman's terms: activating this function for a domain name makes a particular record in the Domain Name System (DNS) which includes the IP addresses of the servers which are permitted to send email messages from mail boxes using the domain. Once this record propagates globally, it will exist on all DNS servers that direct the Internet traffic. Every time some e-mail message is sent, the first DNS server it uses verifies if it comes from an approved server. When it does, it's forwarded to the destination address, however if it doesn't originate from a server listed in the SPF record for the domain, it is discarded. In this way nobody will be able to mask an email address and make it appear as if you're sending spam messages. This approach is also identified as email spoofing.
SPF Protection in Web Hosting
The SPF protection function is provided as standard with every single web hosting
package that we supply and you can use it without any difficulty in order to protect the e-mails for any domain hosted as part of your account. The service is operated through the Emails section of our outstanding, and easy to work with Hepsia Control Panel. All it takes to enable the protection is to type in the IP address of the e-mail server and its hostname - mail.server.com, for instance. The moment the protection is active, only this server will be able to send out e-mail messages from e-mails created under the domain that you have selected. Your e-mails may be taken care of by a different supplier, but in case that we handle them together with your web site, you can activate an option for e-mail messages to be sent only if the domain uses our MX records. This solution provides you with even better protection as exclusively our server will be permitted to send out e-mails from your mailboxes and you'll have better control. If you have any questions or in case you experience any kind of issues with this service, you can contact our tech support team at any time and they will give you a hand without delay.
