SPF, which is an acronym for Sender Policy Framework, is an e-mail protection system, which is is intended to validate if an e-mail message is sent by an authorized server. Employing SPF protection for a particular domain will prevent the faking of emails created with the domain. In layman's terms: enabling this function for a domain name generates a particular record in the Domain Name System (DNS) which includes the IP addresses of the servers that are permitted to send e-mails from mailboxes under the domain. As soon as this record propagates worldwide, it will exist on all DNS servers that direct the Internet traffic. Whenever a new e-mail message is sent, the first DNS server it uses verifies if it originates from an approved server. When it does, it is forwarded to the destination address, yet if it does not come from a server part of the SPF record for the domain, it's discarded. In this way nobody will mask an email address to make it look as if you are sending spam messages. This method is also known as email spoofing.

SPF Protection in Shared Hosting

SPF protection can be activated for each domain name hosted in a shared hosting account on our cloud platform with only a couple of clicks. The option is accessible in the Emails section of our cutting-edge Hepsia Control Panel and all you need to use it is to select one of your domains from a drop-down list and type in the hostnames together with the IPv4 or IPv6 addresses of the mail servers that will be approved to send messages from your email addresses. As an added option you can even restrict the email messages to be sent from your domain only if it includes our MX records, i.e. when our servers manage the email addresses for it, not some third-party supplier. This solution will provide you with the top degree of safety, but it is not applicable if only your web site is on our servers while your email addresses for the domain are handled somewhere else. Either way, our SPF protection service will keep your email addresses protected from being used for spam or scam purposes.

SPF Protection in Semi-dedicated Hosting

When you host your domains in a semi-dedicated server account with us, you can use the SPF protection feature as a part of the regular group of services that you'll get with this kind of web hosting. Enabling the protection will require only a few easy steps within the Hepsia Control Panel, thus even if you haven't used this kind of function before, you will not have any kind of troubles. Through a very time and effort saving interface, you will just have to insert the details of the mail server which will be certified to send out messages from your addresses - its hostname (mail.server.com) and IP address (IPv4 or IPv6). Once the newly made record propagates, nobody will be able to fake any e-mail for that particular domain and send out e-mails from a server other than the one you've typed in. This does not necessarily have to be our mail server, however if we manage your e-mails, you are able to enable one more level of protection by picking an option that emails can be send out from addresses @your-domain.com only in case the domain employs our MX records. Our tech support staff can assist you 24/7 if you have any kind of questions related to this service.
