SPF, which is short for Sender Policy Framework, is an email security system, that is designed to verify whether an email message was sent by an authorized server. Employing SPF protection for a given domain name will stop the forging of email addresses created with the domain. In simple words: enabling this feature for a domain creates a special record in the Domain Name System (DNS) which includes the IP addresses of the servers which are allowed to send emails from mailboxes using the domain. The moment this record propagates worldwide, it will exist on all of the DNS servers that direct the Internet traffic. Any time some email message is sent, the first DNS server it uses verifies whether it originates from an accredited server. When it does, it's sent to the destination address, but when it does not come from a server indexed in the SPF record for the domain, it is rejected. In this way nobody will be able to mask an email address and make it look as if you are distributing spam. This technique is also called email spoofing.

SPF Protection in Cloud Web Hosting

SPF protection can be enabled for any domain name hosted in a cloud web hosting account on our cloud platform with no more than a couple of clicks. The feature is accessible in the Emails section of our state-of-the-art Hepsia Control Panel and what is needed to use it is to select one of your domain names from the drop-down menu and enter the hostnames plus the IPv4 or IPv6 addresses of the email servers which will be certified to send email messages from your emails. As an additional option you may also restrict the messages to be sent from your domain only if it has our MX records, in other words when our servers handle the emails for it, not some third-party supplier. This solution will provide you with the best degree of safety, but it is not applicable in case only your site is on our servers while the email addresses for the domain name are managed somewhere else. In either case, the SPF protection service will keep your email addresses secure from being used for spam and scam purposes.

SPF Protection in Semi-dedicated Servers

When you host your domain names in a semi-dedicated server account with our company, you'll be able to employ the SPF protection feature as a part of the regular collection of services that you will receive with this type of hosting. Starting the protection involves just a few easy steps inside the Hepsia Control Panel, therefore even in case you've never employed this kind of feature before, you will not have any kind of problems. Through an exceptionally time and effort saving interface, you will just have to insert the info of the mail server that will be permitted to send messages from your email addresses - its hostname (mail.server.com) and IP address (IPv4 or IPv6). As soon as the recently created record propagates, no one will be able to forge any e-mail address for that particular domain and send email messages from a server different from the one you've entered. This doesn't specifically have to be our mail server, still when we manage your e-mails, you will be able to enable one more level of protection by choosing an option that e-mail messages can be send out from addresses @your-domain.com only in case the domain uses our MX records. Our tech support staff can help you 24/7 in case you have any questions related to this service.
