SPF, which stands for Sender Policy Framework, is an email protection system, that is designed to validate whether an email message was sent by a certified server. Using SPF protection for a given domain will stop the counterfeiting of email addresses generated with the domain. In simple words: enabling this function for a domain creates a specific record in the Domain Name System (DNS) which includes the IP addresses of the servers that are allowed to send email messages from mail boxes under the domain. As soon as this record propagates worldwide, it will exist on all the DNS servers that route the Internet traffic. Every time an e-mail message is sent, the initial DNS server it uses verifies whether it originates from an authorized server. If it does, it is sent to the destination address, however when it doesn't come from a server indexed in the SPF record for the domain, it's rejected. Thus nobody will mask an email address and make it look as if you're sending spam messages. This technique is also identified as email spoofing.

SPF Protection in Web Hosting

You can enable the SPF protection service for your domains with just a couple of clicks from the Hepsia Control Panel, which comes with all our Linux web hosting. This is performed through the section with an identical name and you'll be able to allow the protection for each and every domain hosted on our revolutionary cloud hosting platform. Using a really intuitive interface, all you have to submit is the hostname of the mail server that will be permitted to send messages from your e-mails and its IPv4 or IPv6 address. Of course, it is possible to include several servers as well, if needed. When your email addresses are taken care of on our end, you may also take advantage of an even more risk-free option by putting a restriction that emails can be sent only when your domains have our MX records. This solution cannot be used if your website is hosted with us, while the email addresses are with some third-party provider. Either way, the SPF protection solution will vastly improve your online safety and prevent others from spoofing your email addresses.

SPF Protection in Semi-dedicated Hosting

When you have a semi-dedicated server account from our company, you'll be able to protect your email addresses by activating the SPF security service for any domain hosted in your account with just a couple of clicks. This is done in the Emails section of the Hepsia Control Panel that is included with the semi-dedicated accounts and even in case you have no previous experience with these kinds of matters, you won't have any difficulties to enable the security. Everything that you'll need to do will be to select a domain name from a drop-down list and then type the mail server hostname and IPv4 or IPv6 address. The moment the new record propagates, messages from your email addresses will be mailed globally only if they're sent from that specific server. When your emails are handled by our company and not by some third-party supplier, you'll also be able to take advantage of an option for emails to be sent only when the domain includes our MX records and the latter would be the safest option.
